This patch moves to use the new clock framework and also moves away from the hardcoded address offsets for DMA getting the dma-address directly from the device tree. Note that the optimal bclk_ratio selection to avoid jitter due to the use of fractional dividers, which is in the current version has been removed, because not all devices support these non power of 2 sized transfers, which resulted in lots of (downstream) modules that use: snd_soc_dai_set_bclk_ratio(cpu_dai, sample_bits * 2); Signed-off-by: Martin Sperl Signed-off-by: Mark Brown --- sound/soc/bcm/bcm2835-i2s.c | 284 ++++++++---------------------------- 1 file changed, 64 insertions(+), 220 deletions(-) diff --git a/sound/soc/bcm/bcm2835-i2s.c b/sound/soc/bcm/bcm2835-i2s.c index 3303d5f58082..1c1f2210387b 100644 --- a/sound/soc/bcm/bcm2835-i2s.c +++ b/sound/soc/bcm/bcm2835-i2s.c @@ -37,6 +37,7 @@ #include #include #include +#include #include #include @@ -46,55 +47,6 @@ #include #include -/* Clock registers */ -#define BCM2835_CLK_PCMCTL_REG 0x00 -#define BCM2835_CLK_PCMDIV_REG 0x04 - -/* Clock register settings */ -#define BCM2835_CLK_PASSWD (0x5a000000) -#define BCM2835_CLK_PASSWD_MASK (0xff000000) -#define BCM2835_CLK_MASH(v) ((v) << 9) -#define BCM2835_CLK_FLIP BIT(8) -#define BCM2835_CLK_BUSY BIT(7) -#define BCM2835_CLK_KILL BIT(5) -#define BCM2835_CLK_ENAB BIT(4) -#define BCM2835_CLK_SRC(v) (v) - -#define BCM2835_CLK_SHIFT (12) -#define BCM2835_CLK_DIVI(v) ((v) << BCM2835_CLK_SHIFT) -#define BCM2835_CLK_DIVF(v) (v) -#define BCM2835_CLK_DIVF_MASK (0xFFF) - -enum { - BCM2835_CLK_MASH_0 = 0, - BCM2835_CLK_MASH_1, - BCM2835_CLK_MASH_2, - BCM2835_CLK_MASH_3, -}; - -enum { - BCM2835_CLK_SRC_GND = 0, - BCM2835_CLK_SRC_OSC, - BCM2835_CLK_SRC_DBG0, - BCM2835_CLK_SRC_DBG1, - BCM2835_CLK_SRC_PLLA, - BCM2835_CLK_SRC_PLLC, - BCM2835_CLK_SRC_PLLD, - BCM2835_CLK_SRC_HDMI, -}; - -/* Most clocks are not useable (freq = 0) */ -static const unsigned int bcm2835_clk_freq[BCM2835_CLK_SRC_HDMI+1] = { - [BCM2835_CLK_SRC_GND] = 0, - [BCM2835_CLK_SRC_OSC] = 19200000, - [BCM2835_CLK_SRC_DBG0] = 0, - [BCM2835_CLK_SRC_DBG1] = 0, - [BCM2835_CLK_SRC_PLLA] = 0, - [BCM2835_CLK_SRC_PLLC] = 0, - [BCM2835_CLK_SRC_PLLD] = 500000000, - [BCM2835_CLK_SRC_HDMI] = 0, -}; - /* I2S registers */ #define BCM2835_I2S_CS_A_REG 0x00 #define BCM2835_I2S_FIFO_A_REG 0x04 @@ -158,10 +110,6 @@ static const unsigned int bcm2835_clk_freq[BCM2835_CLK_SRC_HDMI+1] = { #define BCM2835_I2S_INT_RXR BIT(1) #define BCM2835_I2S_INT_TXW BIT(0) -/* I2S DMA interface */ -/* FIXME: Needs IOMMU support */ -#define BCM2835_VCMMU_SHIFT (0x7E000000 - 0x20000000) - /* General device struct */ struct bcm2835_i2s_dev { struct device *dev; @@ -169,21 +117,23 @@ struct bcm2835_i2s_dev { unsigned int fmt; unsigned int bclk_ratio; - struct regmap *i2s_regmap; - struct regmap *clk_regmap; + struct regmap *i2s_regmap; + struct clk *clk; + bool clk_prepared; }; static void bcm2835_i2s_start_clock(struct bcm2835_i2s_dev *dev) { - /* Start the clock if in master mode */ unsigned int master = dev->fmt & SND_SOC_DAIFMT_MASTER_MASK; + if (dev->clk_prepared) + return; + switch (master) { case SND_SOC_DAIFMT_CBS_CFS: case SND_SOC_DAIFMT_CBS_CFM: - regmap_update_bits(dev->clk_regmap, BCM2835_CLK_PCMCTL_REG, - BCM2835_CLK_PASSWD_MASK | BCM2835_CLK_ENAB, - BCM2835_CLK_PASSWD | BCM2835_CLK_ENAB); + clk_prepare_enable(dev->clk); + dev->clk_prepared = true; break; default: break; @@ -192,28 +142,9 @@ static void bcm2835_i2s_start_clock(struct bcm2835_i2s_dev *dev) static void bcm2835_i2s_stop_clock(struct bcm2835_i2s_dev *dev) { - uint32_t clkreg; - int timeout = 1000; - - /* Stop clock */ - regmap_update_bits(dev->clk_regmap, BCM2835_CLK_PCMCTL_REG, - BCM2835_CLK_PASSWD_MASK | BCM2835_CLK_ENAB, - BCM2835_CLK_PASSWD); - - /* Wait for the BUSY flag going down */ - while (--timeout) { - regmap_read(dev->clk_regmap, BCM2835_CLK_PCMCTL_REG, &clkreg); - if (!(clkreg & BCM2835_CLK_BUSY)) - break; - } - - if (!timeout) { - /* KILL the clock */ - dev_err(dev->dev, "I2S clock didn't stop.

Therefor, rsnd driver wants to control SSI and parent SSI separately. Otherwise it can't use Playback/Capture in the same time. And it has been done by c2dc47d5cf("ASoC: rsnd: rsnd_dai_stream has each mod's status insted of rsnd_mod") before. OTOH, rsnd driver doesn't want to control CTU/MUX/DVC/SSIU/SSI in separately. Otherwise, these will be re-initialized during playing if MUX merges 2 sounds. Because of these picky reasons, this patch re-defines status on each mod, and add new parent_ssi_status on rsnd_dai_stream.

If this is done, the pll and mclk divider are configured to produce the required 256x fs clock when the sample rate is set by hw_params(). These additions make the codec work with the simple-card driver. Card drivers calling set_pll() and set_clkdiv() directly are unaffected.

This includes the system controllers on these systems which are controlled via syscon which uses the regmap API which used readl() and writel() to interact with the hardware, meaning that all writes are converted to little endian when writing to the hardware. This caused a bad interaction with the regmap core in big endian mode since it was not aware of the byte swapping and so ended up performing little endian writes. Unfortunately when this issue was noticed it was addressed by updating the DT for the affected devices to specify them as little endian. This happened to work since it resulted in two endianness swaps which cancelled each other out and gave little endian behaviour but meant that the DT was clearly not accurately describing the hardware. The intention of commit 29bb45f25ff305 (regmap-mmio: Use native endianness for read/write) was to fix this by making regmap default to native endianness but this breaks most other MMIO users where the hardware has a fixed endianness and the implementation uses the __raw accessors which are not intended to be used outside of architecture code. Instead use the newly added native-endian DT property to say exactly what we want for these systems.

This is not safe as these interact poorly with spinlocks and are not guaranteed to generate emulated instructions on at least ARM where regmap is commonly used. The APIs that are provided all provide some byte swapping so this is difficult to do with the current regmap-mmio implementation which attempts to use the regmap core byte swapping. We can fix this by modernising the MMIO implementation to use reg_read() and reg_write() operations which were added after the API was implemented and pass simple unsigned integers through to the bus, making use of the formatting provided by the I/O accessors using a similar pattern to that used by the core. This will be less efficient for block I/O operations since we now enable and disable any required clocks per register but it is not clear that any users of regmap-mmio actually use block I/O and there is room to optimise later. This removes support for big endian I/O on 64 bit registers since no I/O accessors are provided, no current users were found and support can be added easily once they are available. In addition make the default endianness little endian. This was the behaviour prior to 29bb45f25ff305 (regmap-mmio: Use native endianness for read/write) and is the behaviour desired by most existing users, the users have been audited and those that need native endianness converted to request it explicitly. Previously native was documented as the default but due to the byte swapping in the accessors this was not correctly implemented.

The codec includes a low power DSP for voice wake up. The register address is incremental by 4 in the DSP memory map. In order to recover the codec settings in the codec mode and manipulate the DSP mode for voice wake up, we use the multi-level register map. One is for ALSA API in codec mode that can be recovered by cache before recording. Another is for DSP related settings that can be accessed with 32bit address of the DSP in the application of voice wake up.

ASRC if it doesn't exist There are a pair of warnings when ASRC is absent in the DTB: fsl-asoc-card sound: ASoC: no source widget found for ASRC-Playback fsl-asoc-card sound: ASoC: Failed to add route ASRC-Playback -> direct -> CPU-Playback fsl-asoc-card sound: ASoC: no sink widget found for ASRC-Capture fsl-asoc-card sound: ASoC: Failed to add route CPU-Capture -> direct -> ASRC-Capture This is because the driver is still trying to add DAPM routes for ASRC even if it doesn't exist on that platform. The warnings are harmless but it might be annoying. So this patch drops the DAPM routes of ASRC when it's absent in the DAI link.

This patch adds support for SNDRV_PCM_RATE_KNOT so that users can open stream at these rates. As part of this we should always set constraints in arizona_startup, currently we only set the constraints if we already have a clock to limit rates to that family of sample rates. This patch updates this to set a constraint of all rates supported by the chip if we do not already know which family of rates to limit to. Finally we also reduce the list of rates supported in the constraints to only include those that are supported on current parts.

charset=UTF-8 Content-Transfer-Encoding: 8bit In some configurations, the dai registers get written before the bias level is changed in the codec driver. This leads to a situation where an initial write to the serial port register gets ignored, and future writes may as well, since regmap thinks that the codec already holds the value. More specifically, configuring the codec as i2s master would in fact result in the codec running as slave, a situation where no i2s clocks are generated and hence no data is transferred. This change makes sure that regmap only caches writes when the core clock is disabled, and syncs regmap whenever enabling the core clock again.

I have investigated the issue further and found multiple problems that all appeared with the same commit that originally introduced HDIO_GET_32BIT handling in libata back in linux-2.6.8 and presumably also linux-2.4, as the code uses "copy_to_user(arg, &val, 1)" to copy a 'long' variable containing either 0 or 1 to user space. The problems with this are: * On big-endian machines, this will always write a zero because it stores the wrong byte into user space. * In compat mode, the upper three bytes of the variable are updated by the compat_hdio_ioctl() function, but they now contain uninitialized stack data. * The hdparm tool calling this ioctl uses a 'static long' variable to store the result. This means at least the upper bytes are initialized to zero, but calling another ioctl like HDIO_GET_MULTCOUNT would fill them with data that remains stale when the low byte is overwritten. Fortunately libata doesn't implement any of the affected ioctl commands, so this would only happen when we query both an IDE and an ATA device in the same command such as "hdparm -N -c /dev/hda /dev/sda" * The libata code for unknown reasons started using ATA_IOC_GET_IO32 and ATA_IOC_SET_IO32 as aliases for HDIO_GET_32BIT and HDIO_SET_32BIT, while the ioctl commands that were added later use the normal HDIO_* names. This is harmless but rather confusing. This addresses all four issues by changing the code to use put_user() on an 'unsigned long' variable in HDIO_GET_32BIT, like the IDE subsystem does, and by clarifying the names of the ioctl commands.

To enable playback on DP port, enable all pin and converter widget by sending a vendor VERB for a vendor widget to set required bits.

Prusty" Date: Fri, 12 Feb 2016 07:46:05 +0530 Subject: [PATCH 088/351] ASoC: hdac_hdmi: Create widget/route based on nodes enumerated In skylake, HDMI codec enumerates 3 pins and 3 cvts. Stream can be routed from any cvt to any pin based on the connection list queried from the pin. This patch removes the static modelling of widget/route and creates it dynamically based on the codec widgets enumerated. Mux widgets are added to represent the map between a cvt and pin. Ideally the mux widgets should be created based on the connection list queried from the pin widget. But due to HW behavior, if an external display is not connected on a port, querying the connection list returns zero. So create mux widgets to map all the cvt to all pins. At runtime, playback support on a pin can be verified based on the connection list query. Few function in driver have additional arguments now to support this. Signed-off-by: Subhransu S.

This style is expected by current usermode like PulseAudio and CRAS. This patch exports an API which can be used to register Jack based on PCM. This API also establishes the map between PCM and cvt. Further cvt to pin mapping is established with the help of usermode selection based on the board topology. During device probe as the PCMs may not be registered, initial pin sense don't report jack events. So, first time jack reporting is done during user selection of mux control.

But we still have restriction of playback on the default port alone, so remove that. This patch removes the hardcoding of cvt<->pin map from the dai. Cvt and pin for a dai are now derived from the already stored pcm list of device opened. We query connection list of a pin from codec to validate the cvt<->pin map. If connection list returns zero, then monitor is not connected so fail playback. Signed-off-by: Subhransu S.

Charles Keepax Date: Fri, 19 Feb 2016 14:44:41 +0000 Subject: [PATCH 148/351] ASoC: wm_adsp: Avoid narrow race condition on compr pointer There is a very small window between then wm_adsp_compr_free gets call and when the DSP is actually powered down. If we get an IRQ from the DSP in this window then the wm_adsp_compr pointer will be NULL. This patch adds a check for this into the IRQ handler to avoid any issues when this happens.

In fact, if the driver is reloaded the values in registers will be whatever they were set to previously. However, the cache needs to be fully populated at probe time to avoid non-atomic allocations during register access. Special case here is imx21-class SSI, since according to datasheet it don't have SACC{ST,EN,DIS} regs. This fixes hard lockup on fsl_ssi module reload, at least in AC'97 mode.

Values were printed in hex without indicating this by a leading 0x, and despite these normally being required in decimal. Also where the register value isn't the actual value (it s a power-of-two or 0 means 1, 1 means 2, ...) it was unclear whether the actual or register value was shown. This patch changes the log print so that all mathematical values are shown in decimal, all register values are shown in hex with a 0x prefix, and where the register value isn't the actual integer value the decimal integer value is shown in () after the hex register value.

The root cause for this problem is: the workqueue ci_otg may try to remove hcd before the driver resume has finished, and hcd will disconnect the device on it, then, it will call device_release_driver, and holds the device lock "dev->mutex", but it is never unlocked since it waits workqueue writeback to run to flush the block information, but the workqueue writeback is freezable, it is not thawed before driver resume has finished. When the driver (device: sd 0:0:0:0:) resume goes to dpm_complete, it tries to get its device lock "dev->mutex", but it can't get it forever, then the deadlock occurs. Below call stacks show the situation. So, in order to fix this problem, we need to change workqueue ci_otg as freezable, then the work item in this workqueue will be run after driver's resume, this workqueue will not be blocked forever like above case since the workqueue writeback has been thawed too.

157078f64b8a9cd7011b6b900b2f2498df850748 Mon Sep 17 00:00:00 2001 From: Thomas Betker Date: Tue, 10 Nov 2015 22:18:15 +0100 Subject: [PATCH 184/351] Revert "jffs2: Fix lock acquisition order bug in jffs2_write_begin" This reverts commit 5ffd3412ae55 ("jffs2: Fix lock acquisition order bug in jffs2_write_begin"). The commit modified jffs2_write_begin() to remove a deadlock with jffs2_garbage_collect_live(), but this introduced new deadlocks found by multiple users. page_lock() actually has to be called before mutex_lock(&c->alloc_sem) or mutex_lock(&f->sem) because jffs2_write_end() and jffs2_readpage() are called with the page locked, and they acquire c->alloc_sem and f->sem, resp. In other words, the lock order in jffs2_write_begin() was correct, and it is the jffs2_garbage_collect_live() path that has to be changed. Revert the commit to get rid of the new deadlocks, and to clear the way for a better fix of the original deadlock.

This doesn't work though, when the deleted directory contained a child directory which was moved *out*. In the early stages of the fs build we can then end up with an apparent hard link, with the child directory appearing both in its true location, and as a child of the original directory which are this stage of the mount process we don't *yet* know is defunct. To resolve this, take out the early special-casing of the "directories shall not have hard links" rule in jffs2_build_inode_pass1(), and let the normal nlink processing happen for directories as well as other inodes. Then later in the build process we can set ic->pino_nlink to the parent inode#, as is required for directories during normal operaton, instead of the nlink. And complain only *then* about hard links which are still in evidence even after killing off all the unreachable paths.

Without this setup the IOMMU L2 does not fully respect write permissions when handling an ATS translation request. The IOMMU L2 will set PTE dirty bit when handling an ATS translation with write permission request, even when PTE RW bit is clear. This may occur by direct translation (which would cause a PPR) or by prefetch request from the ATC. This is observed in practice when the IOMMU L2 modifies a PTE which maps a pagecache page. The ext4 filesystem driver BUGs when asked to writeback these (non-modified) pages. Enable ATS write permission check in the Kaveri IOMMU L2 if BIOS has not.

That function registers a timer to be triggered at "jiffies + fbcon_ops.cur_blink_jiffies". A new case had been encountered during initialisation of clcd-pl11x: fbcon_fb_registered do_fbcon_takeover -> do_register_con_driver fbcon_startup (A) add_cursor_timer (with cur_blink_jiffies = 0) -> do_bind_con_driver visual_init fbcon_init (B) cur_blink_jiffies = msecs_to_jiffies(vc->vc_cur_blink_ms); If we take an softirq anywhere between A and B (and we do), cursor_timer_handler executes indefinitely. Instead of patching all possible paths that lead to this case one at a time, fix the issue at the source and initialise cur_blink_jiffies to 200ms when allocating fbcon_ops. This was its default value before aforesaid commit. fbcon_cursor or fbcon_init will refine this value downstream.

However, Xiao Guangrong pointed out that the root cause must be that KVM_DEBUGREG_BP_ENABLED is not being set correctly. This can indeed happen due to the lazy debug exit mechanism, which does not call kvm_update_dr7. Fix it by replacing the existing loop (more or less equivalent to kvm_update_dr0123) with calls to all the kvm_update_dr* functions.

However, since the size of the vmemmap area is proportional to the size of the VA area, but it is populated relative to the physical space, we may end up with the struct page array being mapped outside of the vmemmap region. For instance, on my Seattle A0 box, I can see the following output in the dmesg log. vmemmap : 0xffffffbdc0000000 - 0xffffffbfc0000000 ( 8 GB maximum) 0xffffffbfc0000000 - 0xffffffbfd0000000 ( 256 MB actual) We can fix this by deciding that the vmemmap region is not a projection of the physical space, but of the virtual space above PAGE_OFFSET, i.e., the linear region. This way, we are guaranteed that the vmemmap region is of sufficient size, and we can even reduce the size by half.

THERMAL can be a loadable module, which in turn makes this driver impossible to build. It is nicer to make the cpufreq driver a module as well, so this patch turns the option in to a 'tristate' and adapts the dependency accordingly. The driver has no module_exit() function, so it will continue to not support unloading, but it can be built as a module and loaded at runtime now.

We don't want two drivers for the same chip even if mxu11x0 had gotten some much needed clean up before merge.

To modify a syscall number, we were missing to save the new syscall number to gr20 which is then picked up later in assembly again. The effect that the return value couldn't be changed is a side-effect of another bug in the assembly code. When a process is ptraced, userspace expects each syscall to report entrance and exit of a syscall. If a syscall number was given which doesn't exist, we jumped to the normal syscall exit code instead of informing userspace that the (non-existant) syscall exits. This unexpected behaviour confuses userspace and thus the bug was misinterpreted as if we can't change the return value. This patch fixes both problems and was tested on 64bit kernel with 32bit userspace.

That happens, for example, for robust futex state cleanup, but also if the parent has asked for a TID update when the process exits (we clear the child tid field in user space). However, at the time we do those final VM accesses, we've already stopped accepting signals, so the usual "stop waiting for userfaults on signal" code in fs/userfaultfd.c no longer works, and the process can become an unkillable zombie waiting for something that will never happen. To solve this, just make handle_userfault() abort any user fault handling if we're already in the exit path past the signal handling state being dead (marked by PF_EXITING). This VM special case is pretty ugly, and it is possible that we should look at finalizing signals later (or move the VM final accesses earlier). But in the meantime this is a fairly minimally intrusive fix.

This happens because the inlen accommodates ib_uverbs_cmd_hdr which is deducted from the in buffer. This is problematic since the vendor function could be called either from the legacy verb (where the input length mismatches the actual length) or by the extended verb (where the length matches). The vendor has no idea which function calls it and therefore has no way to know how the length variable should be treated. Fixing this by aligning the inlen to the correct length. All vendor drivers either assumed that inlen >= sizeof(vendor_uhw_cmd) or just failed wrongly (mlx5) and fixed in this patch.

It is up to the caller to ensure no active namespace scanning is occuring. To ensure no scan work occurs, the nvme pci driver adds a removing state to the controller device to avoid queueing scan work during removal. The work is flushed after setting the state, so no new scan work can be queued. The lockless removal allows the driver to cleanup a namespace request_queue if the controller fails during removal. Previously this could deadlock trying to acquire the namespace mutex in order to handle such events.

Before 5ff8eaac1636 ("writeback: keep superblock pinned during cgroup writeback association switches"), this could race with umount leading to super_block being destroyed while inodes are pinned for wb switching. 5ff8eaac1636 fixed it by bumping s_active while wb switches are in flight; however, this allowed in-flight wb switches to make umounts asynchronous when the userland expected synchronosity - e.g. fsck immediately following umount may fail because the device is still busy. This patch removes the problematic super_block pinning and instead makes generic_shutdown_super() flush in-flight wb switches. wb switches are now executed on a dedicated isw_wq so that they can be flushed and isw_nr_in_flight keeps track of the number of in-flight wb switches so that flushing can be avoided in most cases. v2: Move cgroup_writeback_umount() further below and add MS_ACTIVE check in inode_switch_wbs() as Jan an Al suggested.

But this now hides the ability to filter events that have a 'comm' field too. For example, sched_migrate_task trace event. That has a 'comm' field of the task to be migrated. echo 'comm == "bash"' > events/sched_migrate_task/filter will now filter all sched_migrate_task events for tasks named "bash" that migrates other tasks (in interrupt context), instead of seeing when "bash" itself gets migrated. This fix requires a couple of changes. 1) Change the look up order for filter predicates to look at the events fields before looking at the generic filters. 2) Instead of basing the filter function off of the "comm" name, have the generic "comm" filter have its own filter_type (FILTER_COMM). Test against the type instead of the name to assign the filter function. 3) Add a new "COMM" filter that works just like "comm" but will filter based on the current task, even if the trace event contains a "comm" field. Do the same for "cpu" field, adding a FILTER_CPU and a filter "CPU".

With the current code, all devices are reported by acpi_dev_present(), regardless of the _STA return values. This causes errors on probe with the wrong machine driver being loaded. This patch essentially reverts 'commit 6f08cbdaac5a ("ASoC: Intel: Use acpi_dev_present()")' and adds code to force the evaluation of the _STA method. A better solution might be to make sure the ACPI subsystem only reports devices with a _STA value of 0xf but apparently it's problematic so dealing with this in the audio subsystem directly.

This is not very smart but not illegal as long as only one device reports present with the _STA method. The ACPI subsystem tracks each device with an extension, e.g. 10EC5640:00 and 10EC5640:01 In the ASoC machine driver, the DAI codec name needs to refer to the ACPI device that reported present, e.g. "i2c-10EC5640:01". The extension will vary depending on how the BIOS is written and which ACPI device is activated. This patch adds a translation function that provides the codec name from the ACPI HID to avoid any hard-coded values in the machine driver.

This input channel might be converted by CTU, and SSI needs to be Multi SSI mode / TDM SSI mode if 6ch input EX) 6ch input, CTU for 2ch, playback 6ch 6ch 2ch 2ch 2ch 2ch -> SRC -> CTU -> MIX -> DVC -> SSIU -> SSI EX) 6ch input, no CTU, Multi SSI, playback 6ch 6ch 6ch 6ch 6ch 2ch -> SRC -> CTU -> MIX -> DVC -> SSIU -> SSI0/SSI1/SSI2 Current driver is using rsnd_get_adinr_chan() / rsnd_get_slot_width() for this purpose, but it is complicated enough without meaning. This patch adds new rsnd_runtime_channel_xxx() which is caring CTU/Multi SSI.
