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.

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.

2024-04-15drm/vmwgfx: Implement virtual crc generationZack Rusin8-35/+553
crc checksums are used to validate the output. Normally they're part of the actual display hardware but on virtual stack there's nothing to automatically generate them. Implement crc generation for the vmwgfx stack. This works only on screen targets, where it's possibly to easily make sure that the guest side contents of the surface matches the host sides output. Just like the vblank support, crc generation can only be enabled via: guestinfo.vmwgfx.vkms_enable = "TRUE" option in the vmx file. Makes IGT's kms_pipe_crc_basic pass and allows a huge number of other IGT tests which require CRC generation of the output to actually run on vmwgfx. Makes it possible to actually validate a lof of the kms and drm functionality with vmwgfx.

2024-04-15drm/vmwgfx: Implement virtual kmsZack Rusin10-64/+302
By default vmwgfx doesn't support vblanking or crc generation which makes it impossible to use various IGT tests to validate vmwgfx. Implement virtual kernel mode setting, which is mainly related to simulated vblank support. Code is very similar to amd's vkms and the vkms module itself, except that it's integrated with vmwgfx three different output technologies - legacy, screen object and screen targets. Make IGT's kms_vblank pass on vmwgfx and allows a lot of other IGT tests to run with vmwgfx. Support for vkms needs to be manually enabled by adding: guestinfo.vmwgfx.vkms_enable = "TRUE" somewhere in the vmx file, otherwise it's off by default.

2024-04-15dma-buf: Do not build debugfs related code when !CONFIG_DEBUG_FSTvrtko Ursulin2-22/+36
There is no point in compiling in the list and mutex operations which are only used from the dma-buf debugfs code, if debugfs is not compiled in. Put the code in questions behind some kconfig guards and so save some text and maybe even a pointer per object at runtime when not enabled.

2024-04-15drm/fb_dma: s/drm_panic_gem_get_scanout_buffer/drm_fb_dma_get_scanout_bufferMaíra Canal1-2/+3
On version 11 of the "drm/panic: Add a drm panic handler" series [1], Thomas suggested to change the name of the function `drm_panic_gem_get_scanout_buffer` to `drm_fb_dma_get_scanout_buffer` and this request was applied on version 12, which is the version that landed [2]. Although the name of the function changed on the C file, it didn't changed on the header file, leading to a compilation error as such: drivers/gpu/drm/imx/ipuv3/ipuv3-plane.c:780:24: error: use of undeclared identifier 'drm_fb_dma_get_scanout_buffer'; did you mean 'drm_panic_gem_get_scanout_buffer'? 780 | .get_scanout_buffer = drm_fb_dma_get_scanout_buffer, | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | drm_panic_gem_get_scanout_buffer ./include/drm/drm_fb_dma_helper.h:23:5: note: 'drm_panic_gem_get_scanout_buffer' declared here 23 | int drm_panic_gem_get_scanout_buffer(struct drm_plane *plane, | ^ 1 error generated. Fix the compilation error by changing `drm_panic_gem_get_scanout_buffer` to `drm_fb_dma_get_scanout_buffer` on the header file.
