drm/ati_pcigart: Fix error code in drm_ati_pcigart_init()

2018-12-17T09:47:17Z

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.

Just move this into a separate header file, and make the two users use it. Reviewed-by: Daniel Vetter Reviewed-by: Alex Deucher Signed-off-by: Dave Airlie

drm/radeon: Fix pci_map_page() error checking

drm: remove address mask param for drm_pci_alloc()

2010-01-07T03:15:50Z

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

drm: ati_pcigart: Fix limit check in drm_ati_pcigart_init().

2009-03-13T04:24:03Z

The variable 'max_pages' is ambiguous. There are two concepts of "pages" being used in this function. First, we have ATI GART pages which are always 4096 bytes. Then, we have system pages which are of size PAGE_SIZE. Eliminate the confusion by creating max_ati_pages and max_real_pages. Calculate and use them as appropriate. Signed-off-by: David S.

drm: ati_pcigart: Need to use PCI_DMA_BIDIRECTIONAL.

2009-03-13T04:24:00Z

The buffers mapped by the PCI GART can be written to by the device, not just read. For example, this happens via the RB_RPTR writeback on Radeon. So we can't use PCI_DMA_TODEVICE else we'll get protection faults on IOMMU platforms. Signed-off-by: David S. Miller Signed-off-by: Dave Airlie
