The functions mipi_dsi_compression_mode() and mipi_dsi_picture_parameter_set() return 0-or-error rather than a buffer size.

G121XCE-L01 is a Color Active Matrix Liquid Crystal Display composed of a TFT LCD panel, a driver circuit, and LED backlight system. The screen format is intended to support the 4:3, 1024(H) x 768(V) screen and either 262k/16.7M colors (RGB 6-bits or 8-bits) with LED backlight driver circuit. All input signals are LVDS interface compatible. Documentation [1] and [2] indicate that G121X1-L03 and G121XCE-L01 are effectively identical panels, use the former as RGB 6-bits variant and add the later as RGB 8-bits variant.

Use display_timing instead of drm_display_mode to define a range of possible display timings supported by this panel. This makes the panel support more flexible and improves compatibility. No functional change is expected. The settings are picked from documentation [1] section 6.1 INPUT SIGNAL TIMING SPECIFICATIONS.

The .bpc = 6 implies .bus_format = MEDIA_BUS_FMT_RGB666_1X7X3_SPWG , add the missing bus_format. Add missing connector type and bus_flags as well. Documentation [1] 1.4 GENERAL SPECIFICATI0NS indicates this panel is capable of both RGB 18bit/24bit panel, the current configuration uses 18bit mode, .bus_format = MEDIA_BUS_FMT_RGB666_1X7X3_SPWG , .bpc = 6. Support for the 24bit mode would require another entry in panel-simple with .bus_format = MEDIA_BUS_FMT_RGB666_1X7X4_SPWG and .bpc = 8, which is out of scope of this fix.

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. Signed-off-by:

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. Signed-off-by:

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.
