drm/amdgpu: rewrite convert_tiling_flags_to_modifier_gfx12

2024-07-01T20:10:47+00:00

There were multiple bugs, like checking SWIZZLE_MODE before checking GFX12_SWIZZLE_MODE, which has undefined behavior. The function had no effect before (it always returned -EINVAL). Signed-off-by: Marek Olšák Acked-by: Alex Deucher Reviewed-by: Aurabindo Pillai Signed-off-by: Alex Deucher

drm/amdgpu: add amdgpu_framebuffer::gfx12_dcc

2024-07-01T20:10:47+00:00

amdgpu_framebuffer doesn't have tiling_flags, so we need this. amdgpu_display_get_fb_info never gets NULL parameters, so checking for NULL was useless. Signed-off-by: Marek Olšák Acked-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: handle gfx12 in amdgpu_display_verify_sizes

2024-07-01T20:10:47+00:00

It verified GFX9-11 swizzle modes on GFX12, which has undefined behavior. Signed-off-by: Marek Olšák Acked-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: don't use amdgpu_lookup_format_info on gfx12

2024-07-01T20:10:46+00:00

It only uses fields for GFX9-11 related to the separate DCC buffer, which doesn't exist in GFX12. Signed-off-by: Marek Olšák Acked-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: check for LINEAR_ALIGNED correctly in check_tiling_flags_gfx6

drm/amd: GFX12 changes for converting tiling flags to modifiers

2024-04-26T21:22:58+00:00

GFX12 swizzle mode and GCC formats changed and is much simpler. Use a seperate function for the same. Changes: * Swizzle mode is now 3 bits only * DCC enablement doesn't come from tiling_flags, it is always set in modifiers * DCC max compressed block size of 128B Signed-off-by: Aurabindo Pillai Acked-by: Rodrigo Siqueira Signed-off-by: Alex Deucher

drm/amd: Drop abm_level property

2024-02-27T15:46:59+00:00

This vendor specific property has never been used by userspace software and conflicts with the panel_power_savings sysfs file. That is a compositor and user could fight over the same data.

drm/amdgpu: Use function for IP version check

drm/amdgpu: register a dirty framebuffer callback for fbcon

2023-08-30T19:25:34+00:00

fbcon requires that we implement &drm_framebuffer_funcs.dirty. Otherwise, the framebuffer might take a while to flush (which would manifest as noticeable lag). However, we can't enable this callback for non-fbcon cases since it may cause too many atomic commits to be made at once. So, implement amdgpu_dirtyfb() and only enable it for fbcon framebuffers (we can use the "struct drm_file file" parameter in the callback to check for this since it is only NULL when called by fbcon, at least in the mainline kernel) on devices that support atomic KMS.
