Jobs can be in-flight when the file descriptor is closed (either because the process did not terminate properly, or because it didn't wait for all GPU jobs to be finished), and apparently panfrost_job_close() does not cancel already running jobs. Let's refcount the MMU context object so it's lifetime is no longer bound to the FD lifetime and running jobs can finish properly without generating spurious page faults. Reported-by:

Currently this has no practial relevance I think because there's not many who can pull off a setup with panfrost and another gpu in the same system. But the rules are that if you're setting an exclusive fence, indicating a gpu write access in the implicit fencing system, then you need to wait for all fences, not just the previous exclusive fence. panfrost against itself has no problem, because it always sets the exclusive fence (but that's probably something that will need to be fixed for vulkan and/or multi-engine gpus, or you'll suffer badly). Also no problem with that against display. With the prep work done to switch over to the dependency helpers this is now a oneliner. Reviewed-by:

More consistency and prep work for the next patch. Aside: I wonder whether we shouldn't just move this entire xarray business into the scheduler so that not everyone has to reinvent the same wheels. Cc'ing some scheduler people for this too. v2: Correctly handle sched_lock since Lucas pointed out it's needed. v3: Rebase, dma_resv_get_excl_unlocked got renamed v4: Don't leak job references on failure (Steven).

Lang Yu authored
Currently, we have a limitted GTT memory size and need a bounce buffer when doing buffer migration between VRAM and SYSTEM domain. The problem is under GTT memory pressure we can't do buffer migration between VRAM and SYSTEM domain. But in some cases we really need that. Eespecially when validating a VRAM backing store BO which resides in SYSTEM domain. v2: still account temporary GTT allocations v3 (chk): revert to the simpler change for now Signed-off-by:

Sometimes drivers need to use bounce buffers to evict BOs. While those reside in some domain they are not necessarily suitable for CS.

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.

Christian König authored
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.
