drm/i915: don't bail out of intel_wait_ring_buffer too early

In the pre-gem days with non-existing hangcheck and gpu reset code,
this timeout of 3 seconds was pretty important to avoid stuck
processes.

But now we have the hangcheck code in gem that goes to great length
to ensure that the gpu is really dead before declaring it wedged.

So there's no need for this timeout anymore. Actually it's even harmful
because we can bail out too early (e.g. with xscreensaver slip)
when running giant batchbuffers. And our code isn't robust enough
to properly unroll any state-changes, we pretty much rely on the gpu
reset code cleaning up the mess (like cache tracking, fencing state,
active list/request tracking, ...).

With this change intel_begin_ring can only fail when the gpu is
wedged, and it will return -EAGAIN (like wait_request in case the
gpu reset is still outstanding).

v2: Chris Wilson noted that on resume timers aren't running and hence
we won't ever get kicked out of this loop by the hangcheck code. Use
an insanely large timeout instead for the HAS_GEM case to prevent
resume bugs from totally hanging the machine.

two clients doing transform feedback don't stomp on each others'

12 years agodrm/exynos: added hdmi display support
Seung-Woo Kim [Wed, 21 Dec 2011 08:39:39 +0000 (17:39 +0900)]
drm/exynos: added hdmi display support

This patch is hdmi display support for exynos drm driver.

There is already v4l2 based exynos hdmi driver in drivers/media/video/s5p-tv
and some low level code is already in s5p-tv and even headers for register
define are almost same. but in this patch, we decide not to consider separated
common code with s5p-tv.

Exynos HDMI is composed of 5 blocks, mixer, vp, hdmi, hdmiphy and ddc.

1. mixer. The piece of hardware responsible for mixing and blending multiple
data inputs before passing it to an output device.  The mixer is capable of
handling up to three image layers. One is the output of VP.  Other two are
images in RGB format.  The blending factor, and layers' priority are controlled
by mixer's registers. The output is passed to HDMI.

2. vp (video processor). It is used for processing of NV12/NV21 data.  An image
stored in RAM is accessed by DMA. The output in YCbCr444 format is send to
mixer.

3. hdmi. The piece of HW responsible for generation of HDMI packets. It takes
pixel data from mixer and transforms it into data frames. The output is send
to HDMIPHY interface.

4. hdmiphy. Physical interface for HDMI. Its duties are sending HDMI packets to
HDMI connector. Basically, it contains a PLL that produces source clock for
mixer, vp and hdmi.

5. ddc (display data channel). It is dedicated i2c channel to exchange display
information as edid with display monitor.

With plane support, exynos hdmi driver fully supports two mixer layes and vp
layer. Also vp layer supports multi buffer plane pixel formats having non
contigus memory spaces.

In exynos drm driver, common drm_hdmi driver to interface with drm framework
has opertion pointers for mixer and hdmi. this drm_hdmi driver is registered as
sub driver of exynos_drm. hdmi has hdmiphy and ddc i2c clients and controls
them. mixer controls all overlay layers in both mixer and vp.

Vblank interrupts for hdmi are handled by mixer internally because drm
framework cannot support multiple irq id. And pipe number is used to check
which display device irq happens.

History
v2: this version
 - drm plane feature support to handle overlay layers.
 - multi buffer plane pixel format support for vp layer.
 - vp layer support

i2c-algo-bit doesn't actually work very well on one card I have access to
(NVS 300), random single-bit errors occur most of the time - what we're
doing now is closer to what xf86i2c.c does.

The original plan was to figure out why i2c-algo-bit fails on the NVS 300,
and fix it.  However, while investigating I discovered i2c-algo-bit calls
cond_resched(), which makes it a bad idea for us to be using as we execute
VBIOS scripts from a tasklet, and there may very well be i2c transfers as
a result.

So, since I already wrote this code in userspace to track down the NVS 300
bug, and it's not really much code - lets use it.
