drm/ast: Fix incorrect free on ioregs

2018-12-08T11:59:07+00:00

commit dc25ab067645eabd037f1a23d49a666f9e0b8c68 upstream.

If the platform has no IO space, ioregs is placed next to the already
allocated regs. In this case, it should not be separately freed.

This prevents a kernel warning from __vunmap "Trying to vfree()
nonexistent vm area" when unloading the driver.

Fixes: 0dd68309b9c5 ("drm/ast: Try to use MMIO registers when PIO isn't supported")

drm/ast: Remove existing framebuffers before loading driver

2018-12-01T08:37:29+00:00

commit 5478ad10e7850ce3d8b7056db05ddfa3c9ddad9a upstream.

If vesafb attaches to the AST device, it configures the framebuffer memory
for uncached access by default. When ast.ko later tries to attach itself to
the device, it wants to use write-combining on the framebuffer memory, but
vesefb's existing configuration for uncached access takes precedence. This
results in reduced performance.

Removing the framebuffer's configuration before loding the AST driver fixes
the problem. Other DRM drivers already contain equivalent code.

drm: drop _mode_ from drm_mode_connector_attach_encoder

2018-07-13T16:40:27+00:00

Again to align with the usual prefix of just drm_connector_. Again
done with sed + manual fixup for indent issues.

drm: drop _mode_ from update_edit_property()

2018-07-13T16:40:27+00:00

Just makes it longer, and for most things in drm_connector.[hc] we
just use the drm_connector_ prefix. Done with sed + a bit of manual
fixup for the indenting.

drm/ast: fix mode_valid's return type

2018-04-25T07:09:22+00:00

The method struct drm_connector_helper_funcs::mode_valid is defined
as returning an 'enum drm_mode_status' but the driver implementation
for this method uses an 'int' for it.

Fix this by using 'enum drm_mode_status' in the driver too.

Backmerge tag 'v4.16-rc7' into drm-next

This was requested by Daniel, and things were getting
a bit hard to reconcile, most of the conflicts were
trivial though.

drm/ttm: add bo as parameter to the ttm_tt_create callback

Instead of calculating the size in bytes just to recalculate the number
of pages from it pass the BO directly to the function.
