don't disable vblank interrupts (similar to r128)
|
|
Should be 0x08 rather than 0xa0, and shouldn't use typedefs.
|
|
This requires updated Mesa to handle the new relocation format.
|
|
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.
|
|
|
|
Switch relocs to using copy from user and remove index and pass buffer
handles in instead.
|
|
Should use vtotal not htotal to figure out if we're in a vblank period.
|
|
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.
|
|
Ack the IRQs correctly (PIPExSTAT first followed by IIR). Don't read
vblank counter registers on disabled pipes (might hang otherwise). And
deal with flipped pipe/plane mappings if present.

This reverts commit bfc29606e4a818897eebca46a5e23bbe7bc3ce25.
This regresses i915 here for me I can't get greater than 0.333 fps with gears

i915_flush_ttm was unconditionally executing a clflush instruction
to (obviously) flush the cache. Instead, check if the cpu supports
clflush, and if not, fall back to calling wbinvd to flush the entire
cache.

This adds new chipset id in drm.

This avoids a sync flush when user-space has already programmed
and MI_FLUSH in the batchbuffer.

(1 << bits) is an undefined value when bits == 32.
gcc may generate 1 with this expression
which will lead to an infinite retry loop in
drm_ht_just_insert_please.
Because of the different implement of hash_long,
this issue is more frequenly see on 64 bit system

Yes, I'm quite aware "real" nv04 doesn't support this, hopefully the GPU
will just ignore those PGRAPH_DEBUG_3 bits on that hw.

xf86-video-nv will now work again after nouveau.

Just to be safe, we don't really know exactly how the tables work yet, so
we can't be certain there's a way to say "page not present".

bug 12108
|
|
This is necessary for AGP to work after running bios init scripts on nv3x, and
is seen in mmio traces of all cards (nv04-nv4x)
I'm not making the equivalent change to nv40_mc.c, as early cards (6200, 6800gt)
use the 0x000018XX PBUS and later cards use the 0x000880XX PBUS and I don't know
the effects of using the wrong one

Don't set the context as valid until it has been loaded

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

I couldn't figure out what drm_bo_type_dc was for; Dave Airlie finally clued
me in that it was the 'normal' buffer objects with kernel allocated pages
that could be mmapped from the drm device file.
I thought that 'drm_bo_type_device' was a more descriptive name.
I also added a bunch of comments describing the use of the type enum values and
the functions that use them.
|

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.
