drm/drivers: add support for using the arch wc mapping API.

2018-09-09T18:04:36+00:00

commit 7cf321d118a825c1541b43ca45294126fd474efa upstream. This fixes a regression in all these drivers since the cache mode tracking was fixed for mixed mappings. It uses the new arch API to add the VRAM range to the PAT mapping tracking tables. Fixes: 87744ab3832 (mm: fix cache mode tracking in vm_insert_mixed()) Reviewed-by: Christian König .

drm/cirrus: Don't grab dev->struct_mutex for in mmap offset ioctl

2015-08-10T11:37:27+00:00

Since David Herrmann's mmap vma manager rework we don't need to grab dev->struct_mutex any more to prevent races when looking up the mmap offset. Drop it and instead don't forget to use the unref_unlocked variant (since the drm core still cares). Reviewed-by: Thierry Reding Signed-off-by: Daniel Vetter

drm/cirrus: Limit modes depending on bpp option

2015-02-05T00:39:00+00:00

The commit [8975626ea35a: drm/cirrus: allow 32bpp framebuffers for cirrus drm] broke X modesetting driver because cirrus driver still provides the full list of modes up to 1280x1024 while the 32bpp can support only up to 800x600. We might be able to filter out the invalid modes in mode_valid callback, but unfortunately the bpp in question can't be referred there for now (let me know if there is a better way to retrieve the bpp for the probed fb). So, instead, this patch adds the bpp module option to specify the maximal bpp explicitly and limits the resolutions in get_modes depending on its value. The default value is set to 24 so that the existing stuff keeps working. If you need a new 32bpp feature, specify cirrus.bpp=32 option explicitly.

drm/fb-helper: Propagate errors from initial config failure

2015-01-21T13:57:03+00:00

Make drm_fb_helper_initial_config() return an int rather than a bool so that the error can be properly propagated. While at it, update drivers to propagate errors further rather than just ignore them. v2: - cirrus: No cleanup is required, the top-level cirrus_driver_load() will do it as part of cirrus_driver_unload() in its cleanup path.

drm/cirrus: fix leaky driver load error handling

2014-11-20T01:41:26+00:00

Before this patch, cirrus_device_init could have failed while cirrus_mm_init succeeded and the driver would have reported overall success on load. This patch causes cirrus_device_init to return on the first error encountered. Reviewed-by: Stéphane Marchesin Signed-off-by: Dave Airlie

drm: Move drm_crtc_init from drm_crtc.h to drm_plane_helper.h

2014-11-04T23:14:55+00:00

Just a bit of OCD cleanup on headers - this function isn't the core interface any more but just a helper for drivers who haven't yet transitioned to universal planes. Put the declaration at the right spot and sprinkle necessary #includes over all drivers. Maybe this helps to encourage driver maintainers to do the switch. v2: Fix #include ordering for tegra, reported by 0-day builder. v3: Include required headers, reported by Thierry.
