We'd only ever used this define to denote whether or not we have the
dynamic parity feature (DPF) and never to determine whether or not L3
exists. Baytrail is a good example of where L3 exists, and not DPF.
This patch provides clarify in the code for future use cases which might
want to actually query whether or not L3 exists.
v2: Add /* DPF == dynamic parity feature */

On both Ivybridge and Haswell, row remapping information is saved and
restored with context. This means, we never actually properly supported
the l3 remapping because our sysfs interface is asynchronous (and not
tied to any context), and the known faulty HW would be reused by the
next context to run.
Not that due to the asynchronous nature of the sysfs entry, there is no
point modifying the registers for the existing context. Instead we set a
flag for all contexts to load the correct remapping information on the
next run. Interested clients can use debugfs to determine whether or not
the row has been remapped.
One could propose at this point that we just do the remapping in the
kernel. I guess since we have to maintain the sysfs interface anyway,
I'm not sure how useful it is, and I do like keeping the policy in
userspace; (it wasn't my original decision to make the
interface the way it is, so I'm not attached).
v2: Force a context switch when we have a remap on the next switch.
(Ville)
Don't let userspace use the interface with disabled contexts.
v3: Don't force a context switch, just let it nop
Improper context slice remap initialization, 1<<1 instead of 1<<i, but I
rewrote it to avoid a second round of confusion.

Added a comment on why the slice remap initialization happens.

I have implemented this patch before without creating a separate list
(I'm having trouble finding the links, but the messages ids are:
<1364942743-6041-2-git-send-email-ben@bwidawsk.net>
<1365118914-15753-9-git-send-email-ben@bwidawsk.net>)
However, the code is much simpler to just use a list and it makes the
code from the next patch a lot more pretty.
As you'll see in the next patch, the reason for this is to be able to
specify when a context needs to get L3 remapping. More details there.

Using LRI for setting the remapping registers allows us to stream l3
remapping information. This is necessary to handle per context remaps as
we'll see implemented in an upcoming patch.

Certain HSW SKUs have a second bank of L3. This L3 remapping has a
separate register set, and interrupt from the first "slice". A slice is
simply a term to define some subset of the GPU's l3 cache. This patch
implements both the interrupt handler, and ability to communicate with
userspace about this second slice.
v2: Remove redundant check about non-existent slice.
Change warning about interrupts of unknown slices to WARN_ON_ONCE
Handle the case where we get 2 slice interrupts concurrently, and switch
the tracking of interrupts to be non-destructive (all Ville)
Don't enable/mask the second slice parity interrupt for ivb/vlv (even
though all docs I can find claim it's rsvd) (Ville + Bryan)
Keep BYT excluded from L3 parity
v3: Fix the slice = ffs to be decremented by one (found by Ville). When
I initially did my testing on the series, I was using 1-based slice
counting, so this code was correct. Not sure why my simpler tests that
I've been running since then didn't pick it up sooner.

I always get royally confused how a modeline with all zeros could
possible pass the paranoid pipe config checker. Until I realize again
that we only check the crtc timings. So dump the crtc timings for the
adjusted mode.
This will be even more important for 3D support where the crtc timings
are markedly different from the input modeline if we have
frame-by-frame 3d output enabled.

Otherwise the system will burn even brighter and worse, leave the user
wondering what's going on exactly.
Since we already have a panic handler which will (try) to restore the
entire fbdev console mode, we can just bail out. Inspired by a patch from
Konstantin Khlebnikov. The callchain leading to this, cut&pasted from
Konstantin's original patch:
callstack:
panic()
bust_spinlocks(1)
unblank_screen()
vc->vc_sw->con_blank()
fbcon_blank()
fb_blank()
info->fbops->fb_blank()
drm_fb_helper_blank()
drm_fb_helper_dpms()
drm_modeset_lock_all()
mutex_lock(&dev->mode_config.mutex)
Note that the entire locking in the fb helper around panic/sysrq and kdbg
is ... non-existant. So we have a decent change of blowing up
everything. But since reworking this ties in with funny concepts like the
fbdev notifier chain or the impressive things which happen around
console_lock while oopsing, I'll leave that as an exercise for braver
souls than me.

After a vmalloc failure in ttm_dma_tt_alloc_page_directory(),
ttm_dma_tt_init() will call ttm_tt_destroy() to cleanup, and end up
inside the driver's unpopulate() hook when populate() has never yet
been called.
On nouveau, the first issue to be hit because of this is that
dma_address[] may be a NULL pointer. After working around this,
ttm_pool_unpopulate() may potentially hit the same issue with
the pages[] array.
It seems to make more sense to avoid calling unpopulate on already
unpopulated TTMs than to add checks to all the implementations.

not all the callers check the return values and (iii) if we ever hit

The current limit for these messages is 20 since we only have 5 data

buffer overflows. The check inside intel_dp_aux_ch is to prevent

We don't want to try to push the hardware beyond it's capabilities,
so check the pixel clock against the display core clock limit. Do
it for pre-gen4 for now since that's where we alread have the double
wide pixel clock limit check.
Let's assume that when double wide mode is enabled the max
pixel clock limit is also doubled.
FIXME: panel fitter downscaling probably affects the limit on
non-pch platforms too, so we'd need another version of
ilk_pipe_pixel_rate() to figure that out.
FIXME: should check the limits on all platforms. Also sprites
affect the max allowed pixel rate on some platforms, so we need
to eventually tie all the planes and pipes into one check in

Rather that mess about with hdisplay/vdisplay from requested_mode, add
explicit pipe src size information to pipe config.
Now requested_mode is only really relevant for dvo/sdvo output timings.
For everything else either adjusted_mode or pipe src size should be
used.
In many places where we end up using pipe source size, we should
actually use the primary plane size, but we don't currently store
that information explicitly. As long as we treat primaries as full
screen only, we can get away with this. Eventually when we move
primaries over to drm_plane, we need to fix it all up.
