5db3d78f - drm/ast: Run DRM default client setup

Tue, 24 Sep 2024 07:12:48 +0000

drm/ast: Run DRM default client setupCall drm_client_setup() to run the kernel's default client setupfor DRM. Set fbdev_probe in struct drm_driver, so that the clientsetup can start the common fbdev client.The ast driver specifies a preferred color mode of 32. As thisis the default if no format has been given, leave it out entirely.v5:- select DRM_CLIENT_SELECTIONSigned-off-by: Thomas Zimmermann Cc: Dave Airlie Cc: Thomas Zimmermann Cc: Jocelyn Falempe Reviewed-by: Jocelyn Falempe Link: https://patchwork.freedesktop.org/patch/msgid/20240924071734.98201-51-tzimmermann@suse.de List of files: /linux-6.15/drivers/gpu/drm/ast/Kconfig

000458b5 - drm: Only select I2C_ALGOBIT for drivers that actually need it

Mon, 19 Dec 2022 08:36:27 +0000

drm: Only select I2C_ALGOBIT for drivers that actually need itWhile working on a drm driver that doesn't need the i2c algobit stuff Inoticed that DRM selects this code even though only 8 drivers actually useit. While also only some drivers use i2c, keep the select for I2C for thenext cleanup patch. Still prepare this already by also selecting I2C forthe individual drivers.Signed-off-by: Uwe Kleine-König Reviewed-by: Javier Martinez Canillas Signed-off-by: Javier Martinez Canillas Link: https://patchwork.freedesktop.org/patch/msgid/20221219083627.1401627-1-u.kleine-koenig@pengutronix.de List of files: /linux-6.15/drivers/gpu/drm/ast/Kconfig

f2fa5a99 - drm/ast: Convert ast to SHMEM

Thu, 13 Oct 2022 11:29:22 +0000

drm/ast: Convert ast to SHMEMReplace GEM VRAM helpers with GEM SHMEM helpers in ast. Avoids OOMerrors when allocating video memory. Also adds support for dma-buffunctionality.Aspeed display hardware supports display resolutions of FullHD andhigher at 32-bit pixel depth. But the amount of video memory is inthe range of 8 MiB to 32 MiB, which adds constraints to the actuallyavailable resolutions. As atomic modesetting with VRAM helpersrequires double buffering in video memory, ast fails to pageflipin some configurations. For example, FullHD with an active cursorplane does not work on devices with 16 MiB of video memory.Resolve this problem by converting the ast driver to GEM SHMEM helpers.Keep the buffer objects in system memory and copy to video memoryon pageflips via shadow-plane helpers. Userspace used to require shadowplanes for decent performance, but that's now provided by the driver.To replace the memory management, the patch also implements damagehandling for the primary plane.With GEM SHMEM helpers, dma-buf import and export is now supportedby ast. This allows easier screen mirroring across devices or withan Aspeed-based BMC.

92b6f89f - drm: Add separate Kconfig option for fbdev helpers

Tue, 08 Oct 2013 15:44:47 +0000

drm: Add separate Kconfig option for fbdev helpersFor drivers which might want to disable fbdev legacy support.Select the new option in all drivers for now, so this shouldn't resultin any change. Drivers need some work anyway to make fbdev supportoptional (if they have it implemented, that is), so the recommendedway to expose this is by adding per-driver options. At least as longas most drivers don't support disabling the fbdev support.v2: Update for new drm drivers msm and rcar-du. Note that Rob's msmdriver can already take advantage of this, which allows us to buildmsm without any fbdev depencies in the kernel!v3: Move the MODULE_* stuff from the fbdev helper file todrm_crtc_helper.c.Cc: David Herrmann Cc: Rob Clark Reviewed-by: Rob Clark Acked-by: Dave Airlie Reviewed-by: Chon Ming Lee Signed-off-by: Daniel Vetter List of files: /linux-6.15/drivers/gpu/drm/ast/Kconfig

312fec14 - drm: Initial KMS driver for AST (ASpeed Technologies) 2000 series (v2)

Wed, 29 Feb 2012 13:40:04 +0000

drm: Initial KMS driver for AST (ASpeed Technologies) 2000 series (v2)This is the initial driver for the Aspeed Technologies chips found inservers. This driver supports the AST 2000, 2100, 2200, 2150 and 2300. Itdoesn't support the AST11xx due to lack of hw to test it on, and them requiringdifferent codepaths.This driver is intended to be used with xf86-video-modesetting in userspace.This driver has a slightly different design than other KMS drivers, butfuture server chips will probably share similiar setup. As these GPUs commonlyhave low video RAM, it doesn't make sense to put the kms console in VRAMalways. This driver places the kms console into system RAM, and does dirtyupdates to a copy in video RAM. When userspace sets a new scanout buffer,it forcefully evicts the video RAM console, and X can create a framebufferthat can use all of of video RAM.This driver uses TTM but in a very simple fashion to control the evictionto system RAM of the console, and multiple servers.v2: add s/r support, fix Kconfig.Signed-off-by: Dave Airlie List of files: /linux-6.15/drivers/gpu/drm/ast/Kconfig
