drm/r128: make ATI PCI GART part of its only user, r128

2019-11-20T09:09:05+00:00

The ATI Rage 128 driver has been the only user of ATI PCI GART code since Radeon dropped UMS support in commit 8333f607a631 ("drm/radeon: remove UMS support"). Clean up the drm top level directory, Kconfig and Makefile by making ati_pcigart.[ch] part of r128. Drop the CONFIG_DRM_ATI_PCIGART config option made redundant by the change. This reduces drm.ko module size slightly when legacy drivers are enabled, and moves the baggage to r128.ko instead.

drm/ati_pcigart: drop dependency on drm_os_linux.h

drm: drop use of drmP.h in drm/*

2019-05-27T16:07:03+00:00

The use of the drmP.h header file is deprecated. Remove use from all files in drm/* so people do not look there and follow a bad example. Build tested allyesconfig,allmodconfig on x86, arm etc. Including alpha that is as always more challenging than the rest.

drm/ati_pcigart: Fix error code in drm_ati_pcigart_init()

2018-12-17T09:47:17+00:00

The drm_ati_pcigart_init() function was originally suppose to return one on success and zero on failure, but these days it returns a mix of zero, one and -ENOMEM on failure. This patch cleans it up and modifies the caller so now the function returns zero on success and negative error codes on failure.

drm: remove address mask param for drm_pci_alloc()

2010-01-07T03:15:50+00:00

drm_pci_alloc() has input of address mask for setting pci dma mask on the device, which should be properly setup by drm driver. And leave it as a param for drm_pci_alloc() would cause confusion or mistake would corrupt the correct dma mask setting, as seen on intel hw which set wrong dma mask for hw status page. So remove it from drm_pci_alloc() function. Signed-off-by: Zhenyu Wang Signed-off-by: Dave Airlie
