drm/loongson: Use video aperture helpers

2024-10-14T13:28:47Z

DRM's aperture functions have long been implemented as helpers under drivers/video/ for use with fbdev. Avoid the DRM wrappers by calling the video functions directly.

drm/loongson: Run DRM default client setup

2024-09-26T07:31:28Z

Call drm_client_setup() to run the kernel's default client setup for DRM. Set fbdev_probe in struct drm_driver, so that the client setup can start the common fbdev client. The loongson driver specifies a preferred color mode of 32. As this is the default if no format has been given, leave it out entirely. v5: - select DRM_CLIENT_SELECTION Signed-off-by: Thomas Zimmermann Cc: Sui Jingfeng Acked-by: Sui Jingfeng Link: https://patchwork.freedesktop.org/patch/msgid/20240924071734.98201-68-tzimmermann@suse.de

drm/fbdev-generic: Convert to fbdev-ttm

2024-05-02T09:33:32Z

Only TTM-based drivers use fbdev-generic. Rename it to fbdev-ttm and change the symbol infix from _generic_ to _ttm_. Link the source file into TTM helpers, so that it is only build if TTM-based drivers have been selected. Select DRM_TTM_HELPER for loongson.

drm/gem: Acquire reservation lock in drm_gem_{pin/unpin}()

2024-03-11T12:33:50Z

Acquire the buffer object's reservation lock in drm_gem_pin() and remove locking the drivers' GEM callbacks where necessary. Same for unpin(). DRM drivers and memory managers modified by this patch will now have correct dma-buf locking semantics: the caller is responsible for holding the reservation lock when calling the pin or unpin callback. DRM drivers and memory managers that are not modified will now be protected against concurent invocation of their pin and unpin callbacks. PRIME does not implement struct dma_buf_ops.pin, which requires the caller to hold the reservation lock. It does implement struct dma_buf_ops.attach, which requires to callee to acquire the reservation lock. The PRIME code uses drm_gem_pin(), so locks are now taken as specified. Same for unpin and detach. The patch harmonizes GEM pin and unpin to have non-interruptible reservation locking across all drivers, as is already the case for vmap and vunmap. This affects gem-shmem, gem-vram, loongson, qxl and radeon.

drm/loongson: Error out if no VRAM detected

2024-01-28T11:06:46Z

When a Loongson laptop is equipped with a Radeon GPU, it can be true that there is no dedicated VRAM soldered on the motherboard. This is probably for cost reason, but drm/loongson driver is probed because the platform BIOS (either UEFI or PMON) forget to disable the integrated GPU. So in the lsdc_get_dedicated_vram() function, we error out if no dedicated VRAM detected. This fix nothing, but serve as a sanity check only.
