2024-04-23drm/v3d: Fix race-condition between sysfs/fdinfo and interrupt handlerMaíra Canal4-4/+25
In V3D, the conclusion of a job is indicated by a IRQ. When a job finishes, then we update the local and the global GPU stats of that queue. But, while the GPU stats are being updated, a user might be reading the stats from sysfs or fdinfo. For example, on `gpu_stats_show()`, we could think about a scenario where `v3d->queue[queue].start_ns != 0`, then an interrupt happens, we update the value of `v3d->queue[queue].start_ns` to 0, we come back to `gpu_stats_show()` to calculate `active_runtime` and now, `active_runtime = timestamp`. In this simple example, the user would see a spike in the queue usage, that didn't match reality. In order to address this issue properly, use a seqcount to protect read and write sections of the code.

This will make it easier to instantiate the GPU stats variables and it will create a structure where we can store all the variables that refer to GPU stats.

Currently, we manually perform all operations to update the GPU stats variables. Apart from the code repetition, this is very prone to errors, as we can see on commit 35f4f8c9fc97 ("drm/v3d: Don't increment `enabled_ns` twice"). Therefore, create two functions to manage updating all GPU stats variables. Now, the jobs only need to call for `v3d_job_update_stats()` when the job is done and `v3d_job_start_stats()` when starting the job.

The tc358775 bridge is pin compatible with earlier tc358765 according to the tc358774xbg_datasheet_en_20190118.pdf documentation. Compared to the tc358765, the tc358775 supports a STBY GPIO and higher data rates. The tc358765 has a register bit for video event mode vs video pulse mode. We must set it to video event mode for the LCD output to work, and on the tc358775, this bit no longer exists. Looks like the registers seem to match otherwise based on a quick glance comparing the defines to the earlier Android kernel tc358765 driver.

2024-04-23drm/bridge: tc358775: fix support for jeida-18 and jeida-24Michael Walle1-12/+9
The bridge always uses 24bpp internally. Therefore, for jeida-18 mapping we need to discard the lowest two bits for each channel and thus starting with LV_[RGB]2. jeida-24 has the same mapping but uses four lanes instead of three, with the forth pair transmitting the lowest two bits of each channel. Thus, the mapping between jeida-18 and jeida-24 is actually the same, except that one channel is turned off (by selecting the RGB666 format in VPCTRL). While at it, remove the bogus comment about the hardware default because the default is overwritten in any case. Tested with a jeida-18 display (Evervision VGG644804).

2024-04-22drm/edid: Parse topology block for all DispID structure v1.xVille Syrjälä2-2/+1
DisplayID spec v1.3 revision history notes do claim that the toplogy block was added in v1.3 so requiring structure v1.2 would seem correct, but there is at least one EDID in edid.tv with a topology block and structure v1.0. And there are also EDIDs with DisplayID structure v1.3 which seems to be totally incorrect as DisplayID spec v1.3 lists structure v1.2 as the only legal value. Unfortunately I couldn't find copies of DisplayID spec v1.0-v1.2 anywhere (even on vesa.org), so I'll have to go on empirical evidence alone. We used to parse the topology block on all v1.x structures until the check for structure v2.0 was added. Let's go back to doing that as the evidence does suggest that there are DisplayIDs in the wild that would miss out on the topology stuff otherwise. Also toss out DISPLAY_ID_STRUCTURE_VER_12 entirely as it doesn't appear we can really use it for anything. I *think* we could technically skip all the structure version checks as the block tags shouldn't conflict between v2.0 and v1.x. But no harm in having a bit of extra sanity checks I guess. So far I'm not aware of any user reported regressions from overly strict check, but I do know that it broke igt/kms_tiled_display's fake DisplayID as that one gets generated with structure v1.0.

2024-04-22drm/panthor: clean up some types in panthor_sched_suspend()Dan Carpenter1-1/+1
These variables should be u32 instead of u64 because they're only storing u32 values. Also static checkers complain when we do: suspended_slots &= ~upd_ctx.timedout_mask; In this code "suspended_slots" is a u64 and "upd_ctx.timedout_mask". The mask clears out the top 32 bits which would likely be a bug if anything were stored there.
