Tue, 24 Sep 2024 07:12:59 +0000

drm/virtgpu: 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 virtgpu 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: David Airlie Cc: Gerd Hoffmann Cc: Gurchetan Singh Cc: Chia-I Wu Acked-by: Javier Martinez Canillas Link: https://patchwork.freedesktop.org/patch/msgid/20240924071734.98201-62-tzimmermann@suse.de List of files: /linux-6.15/drivers/gpu/drm/virtio/Kconfig

72122c69 - drm/virtio: Add option to disable KMS support

Thu, 02 Mar 2023 23:35:06 +0000

drm/virtio: Add option to disable KMS supportAdd a build option to disable modesetting support. This is useful incases where the guest only needs to use the GPU in a headless mode, or(such as in the CrOS usage) window surfaces are proxied to a hostcompositor.As the modesetting ioctls are a big surface area for potential securitybugs to be found (it's happened in the past, we should assume it willagain in the future), it makes sense to have a build option to disablethose ioctls in cases where they serve no legitimate purpose.v2: Use more if (IS_ENABLED(...))v3: Also permit the host to advertise no scanoutsv4: Spiff out commit msgv5: Make num_scanouts==0 and DRM_VIRTIO_GPU_KMS=n behave the samev6: Drop conditionally building virtgpu_display.c and early-out of it's init/fini fxns insteadSigned-off-by: Rob Clark Reviewed-by: Dmitry Osipenko Reviewed-by: Javier Martinez Canillas Reviewed-by: Gerd Hoffmann Signed-off-by: Dmitry Osipenko Link: https://patchwork.freedesktop.org/patch/msgid/20230302233506.3146290-1-robdclark@gmail.com List of files: /linux-6.15/drivers/gpu/drm/virtio/Kconfig

2077ec34 - drivers: gpu: drm: virtio: fix dependency of DRM_VIRTIO_GPU on VIRTIO

Fri, 04 Dec 2020 13:12:21 +0000

drivers: gpu: drm: virtio: fix dependency of DRM_VIRTIO_GPU on VIRTIOVIRTIO itself has no dependencies and therefore can easily be justselect'ed, instead of depending on it. The current depends on causesany others trying to select VIRTIO to fail like this: drivers/gpu/drm/Kconfig:74:error: recursive dependency detected! drivers/gpu/drm/Kconfig:74: symbol DRM_KMS_HELPER is selected by DRM_VIRTIO_GPU drivers/gpu/drm/virtio/Kconfig:2: symbol DRM_VIRTIO_GPU depends on VIRTIO drivers/virtio/Kconfig:2: symbol VIRTIO is selected by GPIO_VIRTIO drivers/gpio/Kconfig:1618: symbol GPIO_VIRTIO depends on GPIOLIB drivers/gpio/Kconfig:14: symbol GPIOLIB is selected by I2C_MUX_LTC4306 drivers/i2c/muxes/Kconfig:47: symbol I2C_MUX_LTC4306 depends on I2C drivers/i2c/Kconfig:8: symbol I2C is selected by FB_DDC drivers/video/fbdev/Kconfig:63: symbol FB_DDC depends on FB drivers/video/fbdev/Kconfig:12: symbol FB is selected by DRM_KMS_FB_HELPER drivers/gpu/drm/Kconfig:80: symbol DRM_KMS_FB_HELPER depends on DRM_KMS_HELPERIt seems that having both 'depends on' as well as 'select' on the same symbolsends us into big trouble, and Kconfig can't break up the circular dependency(note that in the tested configuration, neither I2C, FB or DRM are enabled atall). Perhaps we could consider this a bug in Kconfig, but the trouble caneasily be circumvented by changing 'depends on' into 'select'.DRM_VIRTIO_GPU also depends on VIRTIO_MENU, so even after this change, thatoption will only show up if the user already enabled virtio in the config.This change didn't cause any changes in the .config after menuconfig run,so we should be completely safe here.Signed-off-by: Enrico Weigelt, metux IT consult Reviewed-by: Anthoine Bourgeois Link: http://patchwork.freedesktop.org/patch/msgid/20201204131221.2827-1-info@metux.netSigned-off-by: Gerd Hoffmann List of files: /linux-6.15/drivers/gpu/drm/virtio/Kconfig

c66df701 - drm/virtio: switch from ttm to gem shmem helpers

Thu, 29 Aug 2019 10:32:57 +0000

drm/virtio: switch from ttm to gem shmem helpersvirtio-gpu basically needs a sg_table for the bo, to tell the host wherethe backing pages for the object are. So the gem shmem helpers are aperfect fit. Some drm_gem_object_funcs need thin wrappers to update thehost state, but otherwise the helpers handle everything just fine.Once the fencing was sorted the switch was surprisingly easy and for themost part just removing the ttm code.v4: fix drm_gem_object_funcs name.Signed-off-by: Gerd Hoffmann Acked-by: Daniel Vetter Reviewed-by: Chia-I Wu Link: http://patchwork.freedesktop.org/patch/msgid/20190829103301.3539-15-kraxel@redhat.com List of files: /linux-6.15/drivers/gpu/drm/virtio/Kconfig

dc5698e8 - Add virtio gpu driver.

Mon, 09 Sep 2013 00:02:56 +0000

Add virtio gpu driver.This patch adds a kms driver for the virtio gpu. The xorg modesettingdriver can handle the device just fine, the framebuffer for fbcon isthere too.Qemu patches for the host side are under review currently.The pci version of the device comes in two variants: with and withoutvga compatibility. The former has a extra memory bar for the vgaframebuffer, the later is a pure virtio device. The only concern forthis driver is that in the virtio-vga case we have to kick out thefirmware framebuffer.Initial revision has only 2d support, 3d (virgl) support requiressome more work on the qemu side and will be added later.Signed-off-by: Dave Airlie Signed-off-by: Gerd Hoffmann Acked-by: Michael S.
