drm/mgag200: Reject non-character-cell-aligned mode widths

2015-06-29T19:08:34+00:00

commit 25161084b1c1b0c29948f6f77266a35f302196b7 upstream.

Turns out 1366x768 does not in fact work on this hardware.

drm/mgag200: fix typo causing bw limits to be ignored on some chips

2014-02-13T21:48:03+00:00

commit ec22b4aa993abbd18f5bbbcb20a1c56be3b1d38b upstream.

mode->mdev otherwise the bw limits never kick in.

Reported in RHEL testing.

drm/mgag200: Invalidate page tables when pinning a BO

2013-08-15T05:59:09+00:00

commit ecaac1c866bcda4780a963b3d18cd310d971aea3 upstream.

When a BO gets pinned the placement may get changed. If the memory is
mapped into user space and user space has already accessed the mapped
range the page tables are set up but now point to the wrong memory.
Set bo.mdev->dev_mapping in mgag200_bo_create() to make sure that
ttm_bo_unmap_virtual() called from ttm_bo_handle_move_mem() will take
care of this.

v2: Don't call ttm_bo_unmap_virtual() in mgag200_bo_pin(), fix comment.

drm/mgag200: Added resolution and bandwidth limits for various G200e products.

2013-07-25T21:07:41+00:00

commit abbee6238775c6633a3779962e9e5b5cb9823749 upstream.

At the larger resolutions, the g200e series sometimes struggles with
maintaining a proper output.  Problems like flickering or black bands appearing
on screen can occur.  In order to avoid this, limitations regarding resolutions
and bandwidth have been added for the different variations of the g200e series.
This code was ported from the old xorg mga driver.

drm/mgag200: Fix framebuffer base address programming

2013-05-13T02:17:32+00:00

Higher bits of the base address of framebuffers weren't being
programmed properly. This caused framebuffers that didn't happen to be
allocated at a low enough address to not be displayed properly.

drm/mgag200: Fix writes into MGA1064_PIX_CLK_CTL register

2013-05-13T02:17:22+00:00

The original line,
  WREG_DAC(MGA1064_PIX_CLK_CTL_CLK_DIS, tmp);
wrote tmp into MGA1064_PIX_CLK_CTL_CLK_DIS, where
MGA1064_PIX_CLK_CTL_CLK_DIS is an offset into
MGA1064_PIX_CLK_CTL. Change the line to write properly into
MGA1064_PIX_CLK_CTL. There were other chunks of code nearby that use
the same pattern (but work correctly), so this patch updates them all
to use this new (slightly more efficient) write pattern. The WREG_DAC
macro was causing the DAC_INDEX register to be set to the same value
twice. WREG8(DAC_DATA, foo) takes advantage of the fact that DAC_INDEX
is already at the value we want.

drm/mgag200: Don't change unrelated registers during modeset

2013-05-13T02:16:36+00:00

Registers in indices below 0x18 are totally unrelated to modesetting,
so don't write 0's, or anything else into them on modeset. Most of
these registers are hardware cursor related, so this existing code
interferes with hardware cursor development.
