drm/nouveau: Remove support for legacy contexts/buffers

2023-01-13T08:22:02+00:00

Remove nouveau's support for legacy contexts and buffers. It was required by libdrm earlier than 2.4.33, released in March 2012. A previous attempt in 2013 to remove the functionality [1] had to be reverted [2] as there were still users left. Libdrm 2.4.33 is now almost 11 years old and it is time for userspace to move on. With the nouveau code gone, we can also remove the driver-feature bit DRIVER_KMS_LEGACY_CONTEXT.

After removing drm_pci_alloc/free, some instances where drm_pci_free() would have kfreed the dma handle were skipped. Ensure these handles are freed properly.

drm: Mark AGP implementation and ioctls as legacy

2021-05-10T13:46:58+00:00

Only UMs drivers use DRM's core AGP code and ioctls. Mark the icotls as legacy. Add the _legacy_ infix to all AGP functions. Move the declarations to the public and internal legacy header files. The agp field in struct drm_device is now located in the structure's legacy section. Adapt drivers to the changes. AGP code now depends on CONFIG_DRM_LEGACY.

drm: Upcast struct drm_device.dev to struct pci_device; replace pdev

2021-01-19T08:06:38+00:00

We have DRM drivers based on USB, SPI and platform devices. All of them are fine with storing their device reference in struct drm_device.dev. PCI devices should be no exception. Therefore struct drm_device.pdev is deprecated. Instead upcast from struct drm_device.dev with to_pci_dev(). PCI-specific code can use dev_is_pci() to test for a PCI device. This patch changes the DRM core code and documentation accordingly. v4: * split-off pdev deprecation into separate patch Signed-off-by: Thomas Zimmermann Reviewed-by: Daniel Vetter Acked-by: Sam Ravnborg Tested-by: Andy Lavr Link: https://patchwork.freedesktop.org/patch/msgid/20210118131420.15874-2-tzimmermann@suse.de
