10 years agodrm/i915: don't disable the DP port if the link is lost
Imre Deak [Thu, 16 Jan 2014 16:35:57 +0000 (18:35 +0200)]
drm/i915: don't disable the DP port if the link is lost

Currently if the DP link is lost (either because of a hot unplug, or
failed link status check) we disable the DP port, but leave the rest
of the pipe running. This is incompatible with the modeset disabling
sequence of some platforms/configurations. At least this is the case for
DP ports on the CPU as opposed to PCH.

Atm we'll also get a warning when we do a modeset disable after the
above link lost event, since we expect the DP port to be enabled at this
point (see the bugzilla ticket for the related dmesg).

Note that with this patch we'll still end up disabling the port, thanks
to the HPD uevent and subsequent modeset disable.

See also the next patch fixing the other half of this issue.

Solution suggested by Ville.

drm/i915: Eliminate lots of WARNs when there's no backlight present

calling the backlight code to enable/disable the backlight via the
LVDS code. This leads to some WARNs due to backlight.max being 0.

drm/i915: Add a kludge for DSL incrementing too late and ISR not working

On pre-PCH platforms ISR doesn't seem to be an actual ISR, at least as
far as display interrupts are concerned. Instead it sort of looks like
some ISR bits just directly reflect the corresponding bit from PIPESTAT.
The bit appears in the ISR only if the PIPESTAT interrupt is enabled. So
in that sense it sort of looks a bit like the south interrupt scheme on
PCH platforms. So it goes something a bit like this:
PIPESTAT.status & PIPESTAT.enable -> ISR -> IMR -> IIR -> IER -> actual
interrupt

In any case that means the intel_pipe_in_vblank_locked() doesn't actually
work for pre-PCH platforms. As a last resort, add a similar kludge as radeon
has that fixes things up if we got called from the vblank interrupt,
but the scanline counter value indicates that we're not quite there yet.
We know that the scanline counter increments at hsync but is otherwise
accurate, so we can limit the kludge to the line just prior to vblank
start, instead of the relative distance that radeon uses.

Merge tag 'vmwgfx-next-2014-01-17' of git://people.freedesktop.org/~thomash/linux into drm-next

Pull request of 2014-01-17

Pull request for 3.14. One not so urgent fix, One huge device update.

The pull request corresponds to the patches sent out on dri-devel, except:
[PATCH 02/33], review tag typo pointed out by Matt Turner.
[PATCH 04/33], dropped. The new surface formats are never used.

The upcoming vmware svga2 hardware version 11 will introduce the concept
of "guest backed objects" or -resources. The device will in principle
get all
of its memory from the guest, which has big advantages from the device
point of view.

This means that vmwgfx contexts, shaders and surfaces need to be backed
by guest memory in the form of buffer objects called MOBs, presumably
short for MemoryOBjects, which are bound to the device in a special way.

This patch series introduces guest backed object support. Some new IOCTLs
are added to allocate these new guest backed object, and to optionally
provide
them with a backing MOB.

There is an update to the gallium driver that comes with this update, and
it will be pushed in the near timeframe presumably to a separate mesa branch
before merged to master.

gpu: fix qxl missing crc32_le

Fix build error: qxl uses crc32 functions so it needs to select
CRC32.

Also use angle quotes around a kernel header file name.

drivers/built-in.o: In function `qxl_display_read_client_monitors_config':
(.text+0x19d754): undefined reference to `crc32_le'
