drm/i915: Add dependency on CONFIG_TMPFS

2011-02-17T23:37:18+00:00

commit f7ab9b407b3bc83161c2aa74c992ba4782e87c9c upstream. Without tmpfs, shmem_readpage() is not compiled in causing an OOPS as soon as we try to allocate some swappable pages for GEM.

drm/i915: Select CONFIG_SHMEM

2009-11-25T20:27:42+00:00

The driver requires shmfs as the backing filesystem to handle the buffer objects, so ensure it is selected if the user chooses to build our driver. Fixes: Bug 14662 - Dell E5500 kernel panic with KMS http://bugzilla.kernel.org/show_bug.cgi?id=14662 The revealing nature of the panic is the NULL function pointer dereference in read_cache_page_async().

drm/i915: force mode set at lid open time

2009-09-10T23:10:00+00:00

Some laptop platforms will disable pipes and/or planes at lid close time and not restore them when the lid is opened again. So catch the lid event, and if the lid was opened, force a mode restore. Fixes fdo bug #21230. Acked-by: Matthew Garrett Signed-off-by: Jesse Barnes Signed-off-by: Eric Anholt

drm/kms/radeon: make kms default a runtime option

2009-09-08T01:15:59+00:00

This makes the kms/enable disable a runtime not a build time option. Signed-off-by: Dave Airlie

drm/kms: fix kms helper license + Kconfig

2009-09-08T01:15:58+00:00

Allow the KMS module to work properly, and also rename it to KMS_HELPER so its clearer what its for. Signed-off-by: Dave Airlie

drm: split crtc/fb helpers into a separate module

2009-09-07T05:45:33+00:00

I really don't want to have core drm module rely on CONFIG_FB, so this is the easiest answer. Signed-off-by: Dave Airlie

radeon: Use request_firmware()

2009-08-30T23:09:30+00:00

Loosely based on a patch by Jaswinder Singh Rajput . KMS support by Dave Airlie . For Radeon 100- to 500-series, firmware blobs look like: struct { __be32 datah; __be32 datal; } cp_ucode[256]; For Radeon 600-series, there are two separate firmware blobs: __be32 me_ucode[PM4_UCODE_SIZE * 3]; __be32 pfp_ucode[PFP_UCODE_SIZE]; For Radeon 700-series, likewise: __be32 me_ucode[R700_PM4_UCODE_SIZE]; __be32 pfp_ucode[R700_PFP_UCODE_SIZE]; Signed-off-by: Ben Hutchings Signed-off-by: Dave Airlie

drm/i915: Add missing dependency on Intel AGP support.

2009-06-22T05:13:38+00:00

Users could accidentally enable AGP but not the Intel AGP support, and get a DRM that doesn't probe as a result. Bug #22358. Signed-off-by: Eric Anholt
