drm/ast: Fix incorrect register check for DRAM width

2016-03-09T23:33:26+00:00

commit 2d02b8bdba322b527c5f5168ce1ca10c2d982a78 upstream.

During DRAM initialization on certain ASpeed devices, an incorrect
bit (bit 10) was checked in the "SDRAM Bus Width Status" register
to determine DRAM width.

Query bit 6 instead in accordance with the Aspeed AST2050 datasheet v1.05.

drm/ast: Initialized data needed to map fbdev memory

2016-03-03T23:06:44+00:00

commit 28fb4cb7fa6f63dc2fbdb5f2564dcbead8e3eee0 upstream.

Due to a missing initialization there was no way to map fbdev memory.
Thus for example using the Xserver with the fbdev driver failed.
This fix adds initialization for fix.smem_start and fix.smem_len
in the fb_info structure, which fixes this problem.

drm/ast: Fix HW cursor image

2014-11-14T16:59:52+00:00

commit 1e99cfa8de0f0879091e33cd65fd60418d006ad9 upstream.

The translation from the X driver to the KMS one typo'ed a couple
of array indices, causing the HW cursor to look weird (blocky with
leaking edge colors). This fixes it.

drm: ast,cirrus,mgag200: use drm_can_sleep

2014-01-29T00:51:52+00:00

these 3 were checking in_interrupt but we have situations where
calling vunmap under this could cause a BUG to be hit in
smp_call_function_many. Use the drm_can_sleep macro instead,
which should stop this path from been taken in this case.

drivers: gpu: Mark functions as static in ast_ttm.c

drm: Add separate Kconfig option for fbdev helpers

2013-10-11T21:36:58+00:00

For drivers which might want to disable fbdev legacy support.

Select the new option in all drivers for now, so this shouldn't result
in any change. Drivers need some work anyway to make fbdev support
optional (if they have it implemented, that is), so the recommended
way to expose this is by adding per-driver options. At least as long
as most drivers don't support disabling the fbdev support.

v2: Update for new drm drivers msm and rcar-du. Note that Rob's msm
driver can already take advantage of this, which allows us to build
msm without any fbdev depencies in the kernel!

v3: Move the MODULE_* stuff from the fbdev helper file to
drm_crtc_helper.c.
