2021-10-28drm/amdkfd: Separate pinned BOs destruction from general routineLang Yu5-37/+118
Currently, all kfd BOs use same destruction routine. But pinned BOs are not unpinned properly. Separate them from general routine. v2 (Felix): Add safeguard to prevent user space from freeing signal BO. Kunmap signal BO in the event of setting event page error. Just kunmap signal BO to avoid duplicating the code. Signed-off-by: Lang Yu <[email protected]> Reviewed-by: Felix Kuehling <[email protected]> Signed-off-by: Alex Deucher <[email protected]>

2021-10-28drm/amdgpu: Add kernel parameter support for ignoring bad page thresholdKent Russell3-5/+13
When a GPU hits the bad_page_threshold, it will not be initialized by the amdgpu driver. This means that the table cannot be cleared, nor can information gathering be performed (getting serial number, BDF, etc). If the bad_page_threshold kernel parameter is set to -2, continue to initialize the GPU, while printing a warning to dmesg that this action has been done v2: squash in Luben's fix to restore RAS info reporting Cc: Luben Tuikov <[email protected]> Cc: Mukul Joshi <[email protected]> Signed-off-by: Kent Russell <[email protected]> Acked-by: Felix Kuehling <[email protected]> Reviewed-by: Luben Tuikov <[email protected]> Signed-off-by: Alex Deucher <[email protected]>

Add FourCCs for 10- and 12-bit red formats with padding to 16 bits. They correspond to the V4L2 10- and 12-bit greyscale (V4L2_PIX_FMT_Y10 and V4L2_PIX_FMT_Y12) formats, as well as the Bayer formats with the same bit depth (V4L2_PIX_FMT_SBGGR{10,12} and all other Bayer pattern permutations). These formats are not used by any kernel driver at this point, but need to be exposed to applications by libcamera, which uses DRM FourCCs for pixel formats.

[Why] A deadlock in the kernel occurs when we fallback from the V3 to V2 add_topology_to_display or remove_topology_to_display because they both try to acquire the dtm_mutex but recursive locking isn't supported on mutex_lock().

[WHY] On certain configs, SMU clock table voltages don't match which cause parser to behave incorrectly by leaving dcfclk and socclk table entries unpopulated. [HOW] Currently the function that finds the corresponding clock for a given voltage only checks for exact voltage level matches. In the case that no match gets found, parser now falls back to searching for the max clock which meets the requested voltage (i.e. its corresponding voltage is below requested).

Atm until the DPCD for a connector is read the max link rate and lane count params are invalid. If the connector is modeset, in intel_dp_compute_config(), intel_dp_common_len_rate_limit(max_link_rate) will return 0, leading to a intel_dp->common_rates[-1] access. Fix the above by making sure the max link params are always valid. The above access leads to an undefined behaviour by definition, though not causing a user visible problem to my best knowledge, see the previous patch why. Nevertheless it is an undefined behaviour and it triggers a BUG() in CONFIG_UBSAN builds, hence CC:stable.

2021-10-27drm/i915/dp: Ensure sink rate values are always validImre Deak1-0/+11
Atm, there are no sink rate values set for DP (vs. eDP) sinks until the DPCD capabilities are successfully read from the sink. During this time intel_dp->num_common_rates is 0 which can lead to a intel_dp->common_rates[-1] (*) access, which is an undefined behaviour, in the following cases: - In intel_dp_sync_state(), if the encoder is enabled without a sink connected to the encoder's connector (BIOS enabled a monitor, but the user unplugged the monitor until the driver loaded). - In intel_dp_sync_state() if the encoder is enabled with a sink connected, but for some reason the DPCD read has failed. - In intel_dp_compute_link_config() if modesetting a connector without a sink connected on it. - In intel_dp_compute_link_config() if modesetting a connector with a a sink connected on it, but before probing the connector first. To avoid the (*) access in all the above cases, make sure that the sink rate table - and hence the common rate table - is always valid, by setting a default minimum sink rate when registering the connector before anything could use it. I also considered setting all the DP link rates by default, so that modesetting with higher resolution modes also succeeds in the last two cases above. However in case a sink is not connected that would stop working after the first modeset, due to the LT fallback logic. So this would need more work, beyond the scope of this fix. As I mentioned in the previous patch, I don't think the issue this patch fixes is user visible, however it is an undefined behaviour by definition and triggers a BUG() in CONFIG_UBSAN builds, hence CC:stable. v2: Clear the default sink rates, before initializing these for eDP.

2021-10-26drm/i915/dp: Skip the HW readout of DPCD on disabled encodersImre Deak1-0/+3
Reading out the DP encoders' DPCD during booting or resume is only required for enabled encoders: such encoders may be modesetted during the initial commit and the link training this involves depends on an initialized DPCD. For DDI encoders reading out the DPCD is skipped, do the same on pre-DDI platforms. Atm, the first DPCD readout without a sink connected - which is a likely scneario if the encoder is disabled - leaves intel_dp->num_common_rates at 0, which resulted in intel_dp_sync_state()->intel_dp_max_common_rate() in a intel_dp->common_rates[-1] access. This by definition results in an undefined behaviour, though to my best knowledge in all HW/compiler configurations it actually results in accessing the array item type value preceding the array. In this case the preceding value happens to be intel_dp->num_common_rates, which is 0, so this issue - by luck - didn't cause a user visible problem. Nevertheless it's still an undefined behaviour and in CONFIG_UBSAN builds leads to a kernel BUG() (which revealed this problem for us), hence CC:stable. A related problem in case the encoder is enabled but the sink is not connected or the DPCD readout fails is fixed by the next patch. v2: Amend the commit message describing the root cause of the CONFIG_UBSAN BUG().
