The commit feeb07d0 ("drm/hisilicon/hibmc: Make CONFIG_DRM_HISI_HIBMC depend on ARM64") made the driver Kconfig symbol to depend on ARM64 since it only supports that architecture and loading the module on others would lead to incorrect video modes being used. But it also prevented the driver to be built on other architectures which is useful to have compile test coverage when doing subsystem wide changes. Make the dependency instead to be (ARM64 || COMPILE_TEST), so the driver is buildable when the CONFIG_COMPILE_TEST option is enabled. Signed-off-by:

The sysfb_create_simplefb() function requests a IO memory resource for the simple-framebuffer platform device, but it also marks it as busy which can lead to drivers requesting the same memory resource to fail. Let's drop the IORESOURCE_BUSY flag and let drivers to request it as busy instead. Signed-off-by:

Hot-unplug all firmware-framebuffer devices as part of removing them via remove_conflicting_framebuffers() et al. Releases all memory regions to be acquired by native drivers. Firmware, such as EFI, install a framebuffer while posting the computer. After removing the firmware-framebuffer device from fbdev, a native driver takes over the hardware and the firmware framebuffer becomes invalid. Firmware-framebuffer drivers, specifically simplefb, don't release their device from Linux' device hierarchy. It still owns the firmware framebuffer and blocks the native drivers from loading. This has been observed in the vmwgfx driver. [1] Initiating a device removal (i.e., hot unplug) as part of remove_conflicting_framebuffers() removes the underlying device and returns the memory range to the system.

In nvkm_acr_hsfw_load_bl(), the return value of kmalloc() is directly passed to memcpy(), which could lead to undefined behavior on failure of kmalloc(). Fix this bug by using kmemdup() instead of kmalloc()+memcpy(). This bug was found by a static analyzer. Builds with 'make allyesconfig' show no new warnings, and our static analyzer no longer warns about this code.

In order to support the YUV output, we'll need the atomic state to know what is the state of the associated property in the CSC setup callback. Let's change the prototype of that callback to allow us to access it. Acked-by:

The current CSC setup code for the BCM2711 uses a sequence of register writes to configure the CSC depending on whether we output using a full or limited range. However, with the upcoming introduction of the YUV output, we're going to add new matrices to perform the conversions, so we should switch to something a bit more flexible that takes the matrix as an argument and programs the CSC accordingly.

The CSC callbacks takes a boolean as an argument to tell whether we're using the full range or limited range RGB. However, with the upcoming YUV support, the logic will be a bit more complex. In order to address this, let's make the callbacks take the entire mode, and call our new helper to tell whether the full or limited range RGB should be used. Acked-by:

The current code assumes that the RGB444 and YUV444 formats are the same, but the HDMI 2.0 specification states that: The three DC_XXbit bits above only indicate support for RGB 4:4:4 at that pixel size. Support for YCBCR 4:4:4 in Deep Color modes is indicated with the DC_Y444 bit. If DC_Y444 is set, then YCBCR 4:4:4 is supported for all modes indicated by the DC_XXbit flags. So if we have YUV444 support and any DC_XXbit flag set but the DC_Y444 flag isn't, we'll assume that we support that deep colour mode for YUV444 which breaks the specification. In order to fix this, let's split the edid_hdmi_dc_modes field in struct drm_display_info into two fields, one for RGB444 and one for YUV444. Suggested-by:

The current code, when parsing the EDID Deep Color depths, that the YUV422 cannot be used, referring to the HDMI 1.3 Specification. This specification, in its section 6.2.4, indeed states: For each supported Deep Color mode, RGB 4:4:4 shall be supported and optionally YCBCR 4:4:4 may be supported. YCBCR 4:2:2 is not permitted for any Deep Color mode. This indeed can be interpreted like the code does, but the HDMI 1.4 specification further clarifies that statement in its section 6.2.4: For each supported Deep Color mode, RGB 4:4:4 shall be supported and optionally YCBCR 4:4:4 may be supported. YCBCR 4:2:2 is also 36-bit mode but does not require the further use of the Deep Color modes described in section 6.5.2 and 6.5.3. This means that, even though YUV422 can be used with 12 bit per color, it shouldn't be treated as a deep color mode. This is also broken with YUV444 if it's supported by the display, but DRM_EDID_HDMI_DC_Y444 isn't set. In such a case, the code will clear color_formats of the YUV444 support set previously in drm_parse_cea_ext(), but will not set it back. Since the formats supported are already setup properly in drm_parse_cea_ext(), let's just remove the code modifying the formats in drm_parse_hdmi_deep_color_info() Fixes: d0c94692 ("drm/edid: Parse and handle HDMI deep color modes.")

The drm_hdmi_avi_infoframe_colorspace() function actually sets the colorimetry and extended_colorimetry fields in the hdmi_avi_infoframe structure with DRM_MODE_COLORIMETRY_* values. To make things worse, the hdmi_avi_infoframe structure also has a colorspace field used to signal whether an RGB or YUV output is being used. Let's remove the inconsistency and allow for the colorspace usage by renaming the function. Reviewed-by:

Also add notes that for atomic drivers it's really somewhere else and no longer in struct drm_crtc. Maybe we should put a bigger warning here that this is confusing, since the pixel format is a plane property, but the GAMMA_LUT property is on the crtc. But I think we can fix this if/when someone finds a need for a per-plane CLUT, since I'm not sure such hw even exists. I'm also not sure whether even hardware with a CLUT and a full color correction pipeline with degamm/cgm/gamma exists. Motivated by comments from Geert that we have a gap here. v2: More names for color luts (Laurent). Reviewed-by:
