The driver can know what hardware requires MI_BATCH_BUFFER vs
MI_BATCH_BUFFER_START; there's no reason to let user mode configure this.

The i915 driver now works again.
|
|
Add code to get panel modes from the VBIOS if present and check whether certain
outputs exist. Should make our display detection code a little more robust.
|
|
It would be nice if one day the DRM driver was the canonical source for
register definitions and core macros. To that end, this patch cleans
things up quite a bit, removing redundant definitions (some with
different names referring to the same register) and generally tidying up
the header file.
|
|
We need to alloc a hw status page bo for G33 if modeset is enabled since the 2D
driver can't alloc gfx memory when working in drm modeset.
|
|
Map the VBIOS (and therefore VBT) at init time for use by various output
initialization routines.

Turns out it's important to save/restore AR14 in particular.

From Jesse and Zhenyu originally.

The vblank tasklet update code must build 2D blt commands with the
appropriate tiled flags.
|

Ported from Xorg intel 2d driver. Changed interfaces definitions, which needed
to be changed later if other device wants to use these DVO stuff.

Doesn't yet work on my i915 test machine, but most of the necessary bits
should be there.

Bump driver minor to 13 due to introduction of new
relocation type.

Also adjust i915 irq handling as it follows the 16bit'ism's
of the i8xx series.

My 965GM gets interrupts stuck when using the old PIPE_VBLANK interrupt.
Switch to the PIPE_EVENT interrupt mechanism, and set the PIPE*STAT
registers to use START_VBLANK on 965 and VBLANK on previous chips.

Failing to preserve the MI_ARB_STATE register was causing FIFO underruns on
the VGA output on my HP 2510p after resume.
|
|
Ported from xf86-video-intel. Still need to tie in TV modes somehow, though
preferably w/o using the properties mechanism.
|
|
|
|
|
|
Make sure we have enough room for all the GR registers or we'll end up
clobbering the AR index register (which should actually be harmless
unless the BIOS is making an assumption about it).
|
|
On resume, if the interrupt state isn't restored correctly, we may end
up with a flood of unexpected or ill-timed interrupts, which could cause
the kernel to disable the interrupt or vblank events to happen at the
wrong time. So save/restore them properly.
|

since a breadcrumb may actually turn up before a corresponding fence object
has been placed on the fence ring.

Add a "command_stream_barrier" method to the bo driver.

We need to return an accurate vblank count to the callers of
->get_vblank_counter, and in the Intel case the actual frame count
register isn't udpated until the next active line is displayed, so we
need to return one more than the frame count register if we're currently
in a vblank period.
However, none of the various ways of doing this is working yet, so
disable the logic for now. This may result in a few missed events, but
should fix the hangs some people have seen due to the current code
tripping the wraparound logic in drm_update_vblank_count.
|
|
One to many parantheses...
|
|
|
|
The frame count registers don't increment until the start of the next
frame, so make sure we return an incremented count if called during the
actual vblank period.

This adds new chipset id in drm.

As DRM_DEBUG macro already prints out the __FUNCTION__ string (see
drivers/char/drm/drmP.h), it is not worth doing this again. At some
other places the ending "\n" was added.
airlied:- I cleaned up a few that this patch missed also

Flags pending validation were stored in a misleadingly named field, 'mask'.
As 'mask' is already used to indicate pieces of a flags field which are
changing, it seems better to use a name reflecting the actual purpose of
this field. I chose 'proposed_flags' as they may not actually end up in
'flags', and in an case will be modified when they are moved over.
This affects the API, but not ABI of the user-mode interface.
