drm: fix leaked dma handles after removing drm_pci_free

2021-05-26T19:18:13+00:00

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.

Added a "break" in the default case of a switch select statement. GCC complains, although this "break" is not strictly necessary for the code to work as expected. Signed-off-by: Fabio M.

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
