Hi Michel:
I'm doing a task which require LRIs to load root pointer around RCS
context switch.My BDW CPU is C stepping. And what I found is
MI_SET_CONTEXT instruction will save/restore PDP0/1/2/3. It's weired
that as part of EXECLIST context, the EXECLIST PPGTT base context also

Hi Chris:
Thanks for the reply. :) I can understand that the backing storage
is pinned at this time, as the reference counter of context object
should not be zero. But for VMA, is there any chance that the vma will
be unbinded from GGTT at this time by shrinker? I saw that
Hi Chris:
Thanks for the reply! I just dig the code. It looks there is no
special code path for execlist shutdown. It has init_rings(), but
doesn't have cleanup_rings(), only clean_ring(), which are called for
each ring one by one when i915_gem_cleanup_ringbuffer() gets called.
Do you
Thanks! :D
Thanks,
Zhi.

Hi Experts:
Recently we found that when i915 module got unloaded, when we were
debugging some bugs in XenGT. It would not reset HW under execlist mode.
I'm not sure if this is an issue. But if we keep loading/unloading
module with the different submission mode, e.g. from execlist mode to
Hi Chris and Mika:
Thanks for the comments. I think that reset HW on module unload is
an good idea. For now I think we should choose a proper position in the
module unload sequence to reset HW. As GPU reset is render engine reset
plus ring imrs(They will become to alll F after full GPU
Hi Gurus:
Recently we found that the wait_for() marco in intel_drv.h looks
will cause dead lock. wait_for() macro will try to wait jiffies change
in a condition check loop, but when local cpu interrupt is disabled, it
seems the jiffies will never change under a uni-processor environment.

Hi Gurus:
I'm curious about the register GFX_FLSH_CNT(0x101008) in

Hi William:
There is a kind of display register marked as double-buffered. It
means that HW will *not* latch the value in the register all the time.
HW will only latch the value on the start of the vertical blank, or the
time when pipe/plane are enabling.
So you will see some code pieces
Thanks Ville! Learned from you guys. :)
