Symptom is random switching of speakers when using multichannel. Repeatedly running speakertest -c8 occasionally starts with channels jumbled. This is fixed with HD_CTL_WHOLSMP. The other bit looks beneficial and apears harmless in testing so I'd suggest adding it too. Documentation says: HD_CTL_WHILSMP_SET Wait for whole sample. When this bit is set MAI transmit will start only when there is at least one whole sample available in the fifo. Documentation says: HD_CTL_CHALIGN_SET Channel Align When Overflow. This bit is used to realign the audio channels in case of an overflow. If this bit is set, after the detection of an overflow, equal amount of dummy words to the missing words will be written to fifo, filling up the broken sample and maintaining alignment.

The drm_connector detect, drm_dp_aux transfer and mipi_dsi_host operations typically require to access their underlying device to perform what is expected of them. However, there's no guarantee on the fact that the device has been enabled through atomic_enable or similar that will usually power the device. The access to an unpowered device is then an undefined behaviour ranging from the access being ignored to a hard CPU hang. Let's document that expectation to avoid as much as possible those consequences. Signed-off-by:

Default list_limit and size_limit_mb are not big enough to cover all possible use cases. For example, list_limit could be well over its default, 1024 if only one or several pages are chained in all individual list entries when creating dmabuf backed by >4MB buffer. list_limit and size_limit_mb are now defined as module parameters so that those can be optionally configured by root with proper values to remove these constraints.

Christian and me realized we have a pretty massive disconnect about different interpretations of what dma_resv is used for by different drivers. The discussion is much, much bigger than this change here, but this is an important one: Non-dynamic exporters must guarantee that the memory they return is ready for use. They cannot expect importers to wait for the exclusive fence. Only dynamic importers are required to obey the dma_resv fences strictly (and more patches are needed to define exactly what this means). Christian has patches to update nouvea, radeon and amdgpu. The only other driver using both ttm and supporting dma-buf export is qxl, which only uses synchronous ttm_bo_move. v2: To hammer this in document that dynamic importers _must_ wait for the exclusive fence after having called dma_buf_map_attachment.

Drop the workaround and instead implement a better solution. Basically we are now chaining all submissions using a dma_fence_chain container and adding them as exclusive fence to the dma_resv object. This way other drivers can still sync to the single exclusive fence while amdgpu only sync to fences from different processes. v3: add the shared fence first before the exclusive one Signed-off-by:

The driver currently iterates over all connectors to get the bus format, used to configure the LVDS output format. This causes several issues: - If other connectors than the LVDS output are present, the format used by the driver may end up belonging to an entirely different output. - The code can crash if some connectors are not connected, as bus_format may then be NULL. - There's no guarantee that the bus format on the connector at the output of the pipeline matches the output of the sn65dsi83, as there may be other bridges in the pipeline. Solve this by retrieving the format from the bridge state instead, which provides the format corresponding to the output of the bridge. The struct sn65dsi83 lvds_format_24bpp and lvds_format_jeida fields are moved to local variables in sn65dsi83_atomic_enable() as they're now used in that function only. Signed-off-by:

Patching the connector format is causing various problematic side effects. Implement .atomic_get_input_bus_fmts callback instead, which sets up the input (DSI-end) format, and that format can then be used in pipeline format negotiation between the DSI-end of this bridge and the other component closer to the scanout engine.

Currently a loop scans through the connector list checking for connectors that do not match a specific criteria. The use of the continue statement is a little unintuitive and can confuse static analysis checking. Invert the criteria matching logic and use a break to terminate the loop once the first suitable connector has been found.

Historically our device headers have been forked versions of the internal device headers, this has made maintaining them a bit of a burden. To fix the situation, going forward, the device headers will be verbatim copies of the internal headers. To do that the driver code has to be adapted to use pristine device headers. This will make future update to the device headers trivial and automatic. Signed-off-by:

Overview ======== The patch adds DMA-BUF statistics to /sys/kernel/dmabuf/buffers. It allows statistics to be enabled for each DMA-BUF in sysfs by enabling the config CONFIG_DMABUF_SYSFS_STATS. The following stats will be exposed by the interface: /sys/kernel/dmabuf/buffers/<inode_number>/exporter_name /sys/kernel/dmabuf/buffers/<inode_number>/size /sys/kernel/dmabuf/buffers/<inode_number>/attachments/<attach_uid>/device /sys/kernel/dmabuf/buffers/<inode_number>/attachments/<attach_uid>/map_counter The inode_number is unique for each DMA-BUF and was added earlier [1] in order to allow userspace to track DMA-BUF usage across different processes. Use Cases ========= The interface provides a way to gather DMA-BUF per-buffer statistics from production devices. These statistics will be used to derive DMA-BUF per-exporter stats and per-device usage stats for Android Bug reports. The corresponding userspace changes can be found at [2]. Telemetry tools will also capture this information(along with other memory metrics) periodically as well as on important events like a foreground app kill (which might have been triggered by Low Memory Killer). It will also contribute to provide a snapshot of the system memory usage on other events such as OOM kills and Application Not Responding events. Background ========== Currently, there are two existing interfaces that provide information about DMA-BUFs. 1) /sys/kernel/debug/dma_buf/bufinfo debugfs is however unsuitable to be mounted in production systems and cannot be considered as an alternative to the sysfs interface being proposed. 2) proc/<pid>/fdinfo/<fd> The proc/<pid>/fdinfo/<fd> files expose information about DMA-BUF fds. However, the existing procfs interfaces can only provide information about the buffers for which processes hold fds or have the buffers mmapped into their address space. Since the procfs interfaces alone cannot provide a full picture of all DMA-BUFs in the system, there is the need for an alternate interface to provide this information on production systems. The patch contains the following major improvements over v1: 1) Each attachment is represented by its own directory to allow creating a symlink to the importing device and to also provide room for future expansion. 2) The number of distinct mappings of each attachment is exposed in a separate file. 3) The per-buffer statistics are now in /sys/kernel/dmabuf/buffers inorder to make the interface expandable in future. All of the improvements above are based on suggestions/feedback from Daniel Vetter and Christian König. A shell script that can be run on a classic Linux environment to read out the DMA-BUF statistics can be found at [3](suggested by John Stultz).
