The function ttm_bo_put releases a reference to a TTM buffer object. The function's name is more aligned to the Linux kernel convention of naming ref-counting function _get and _put. A call to ttm_bo_unref takes the address of the TTM BO object's pointer and clears the pointer's value to NULL. This is not necessary in most cases and sometimes even worked around by the calling code. A call to ttm_bo_put only releases the reference without clearing the pointer. The current behaviour of cleaning the pointer is kept in the calling code, but should be removed if not required in a later patch. Signed-off-by:

usb_write_port_complete() in usb_ops_linux.c is a completion handler function for the USB driver. So it should not sleep, but it is can sleep according to the function call paths (from bottom to top) in Linux-4.16: [FUNC] kzalloc(GFP_KERNEL) drivers/staging/rtl8188eu/core/rtw_cmd.c, 1081: kzalloc in rtw_chk_hi_queue_cmd drivers/staging/rtl8188eu/os_dep/usb_ops_linux.c, 604: rtw_chk_hi_queue_cmd in usb_write_port_complete [FUNC] kzalloc(GFP_KERNEL) drivers/staging/rtl8188eu/core/rtw_cmd.c, 1075: kzalloc in rtw_chk_hi_queue_cmd drivers/staging/rtl8188eu/os_dep/usb_ops_linux.c, 604: rtw_chk_hi_queue_cmd in usb_write_port_complete To fix these bugs, GFP_KERNEL is replaced with GFP_ATOMIC.

Currently we have structrues comp (which is empty) and comp_info being used to register and deregister the component. This mismatch in naming occurred from a previous commit that renamed aim_info to comp. Fix this to use consistent component naming in line with most/net, most/sound etc. This fixes the message two issues, one with a null empty name when loading the module: [ 1485.269515] most_core: registered new core component (null) and an Oops when removing the module: [ 1485.277971] BUG: unable to handle kernel NULL pointer dereference at 0000000000000008 [ 1485.278648] PGD 0 P4D 0 [ 1485.279253] Oops: 0002 [#2] SMP PTI [ 1485.279847] CPU: 1 PID: 32629 Comm: modprobe Tainted: P D WC OE 4.18.0-8-generic #9 [ 1485.280442] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 0.0.0 02/06/2015 [ 1485.281040] RIP: 0010:most_deregister_component+0x3c/0x70 [most_core] .. etc Fixes: 1b10a031 ("staging: most: video: remove aim designators") Signed-off-by:

Instead of creating a dummy child device to manage the card object, just use devm stuff directly for releasing with snd_card_free(). This results in a lot of code reduction. Since the dummy child devices are gone, the device object to be passed to the memory allocator needs to be adjusted as well. Signed-off-by:

The recent ALSA PCM core supports the SNDRV_PCM_INFO_SYNC_APPLPTR flag indicating that the driver needs the ack call at each appl_ptr update. This is requirement for the indirect PCM implementations like bcm2835-audio driver, too. Signed-off-by:

The memory access to the pages allocated with SNDRV_DMA_TYPE_CONTINUOUS are basically non-coherent, and it becomes a problem when a process accesses via mmap. For the more consistent access, use the device coherent memory, just by replacing the call pattern in the allocator helpers. The only point we need to be careful for is the device object passed there; since bcm2835-audio driver creates fake devices and each card is created on top of that, we need to pass its parent device as the real device object.

This is the most significant part in the patch series. The bcm2835-audio driver used to queue the commands to vc04 core via workqueue, but basically the whole accesses to vc04 core are done in the sleepable context, including the callback calls. In such a case, rewriting the code using non-atomic PCM ops will simplify the logic a lot. This patch does it: all workqueue are gone and each former-work implementation is now directly called from PCM ops like trigger and write transfer. Along with it, the DMA position updater, bcm2835_playback_fifo(), was also rewritten to use a simpler logic. Now it handles the XRUN and draining properly by calling snd_pcm_stop() conditionally. The current position is kept in atomic_t value so that it can be read concurrently from the pointer callback. Also, the bcm2835_audio_instance object is allocated at the beginning of bcm2835_audio_open(). This makes the resource management clearer. Signed-off-by:

This is a cleanup and code refactoring in bcm2835-vchiq.c. The major code changes are to provide local helpers for easier use of lock / unlock, and message passing with/without response wait. This allows us to reduce lots of open codes. Also, the max packet is set at opening the stream, not at each time when the write gets called. Signed-off-by:

The bcm2835_audio_instance object contains the array of VCHI_SERVICE_HANDLE_T, while the code assumes and uses only the first element explicitly. Let's reduce to a single vchi handle for simplifying the code. Signed-off-by:
