The cursor_set2 hook provides the cursor hotspot position within the
cursor image. When the hotspot position changes, we can adjust the cursor
position such that the hotspot doesn't move on the screen. This prevents
the cursor from appearing to intermittently jump around on the screen
when the position of the hotspot within the cursor image changes.

Currently after doing DPMS-OFF on all outputs CDCLK won't be set to its
minimum value as it should. A subsequent modeset to turn off all outputs
will thus run with all power domains disabled, and notice that it needs
to change CDCLK to its minimum value. Since the power domains are
disabled this will emit a register-access-while-suspended WARN and fail
to set the minimum freq.
The proper solution for this is to set the minimum frequency during
DPMS-OFF. That needs a bigger rework that would take into account the
user DPMS setting too during the calculation of the new modesetting
configuration. Until that's done this stop-gap solution gets the PIPE-A
power domain during setting the CDCLK; this domain covers the HW blocks
needed for this.
Idea to use PIPE-A domain from Ville.

Trying to read the status of the power wells right after taking forcewake
for the other register reads makes little sense. Most of the time the
power wells will still be up due to the recent forcewake. Instead do the
power well status read first, and only then read the register needing
forcewake. This way the reported power well status can actually reflect
what's going on in the system.

Let's just throw in the towel on this one and take the cheap way out.
Based on a patch from Chris Wilson, but checking for a different bit.
Chris' patch checked for even bank layout, this one here for a magic
bit. Given the evidence we've gathered (not much) both work I think,
but checking for the magic bit might be more accurate.
Anyway, works on my gm45 here.
For paranoi restrict to gen4 (and mobile), since we've only ever seen
this on gm45 and i965gm.
Also add some debugfs output so that we can skip the tiled swapping

Added gen6_init_rps_frequencies() to initialize
the rps frequency values. This function replaces
parse_rp_state_cap(). In addition to reading RPn,
RP0, and RP1 from RP_STATE_CAP register, the new
function reads efficient frequency (aka RPe) from
pcode for Haswell and Broadwell and sets the turbo
softlimits. The turbo minimum frequency softlimit
is set to RPe for Haswell and Broadwell and to RPn
otherwise.
For RPe, the efficiency is based on the frequency/power
ratio (MHz/W); this is considering GT power and not
package power. The efficent frequency is the highest
frequency for which the frequency/power ratio is within
some threshold of the highest frequency/power ratio.
A fixed decrease in frequency results in smaller
decrease in power at frequencies less than RPe than
at frequencies above RPe.
v2: Following suggestions from Chris Wilson and
Daniel Vetter to extend and rename parse_rp_state_cap
and to open-code a poorly named function.

I guess for hysterical raisins this was meant to be the way to read
blob properties. But that's done with the two-stage approach which
uses separate blob kms object and the special-purpose get_blob ioctl.
Shipping userspace seems to have never relied on this, and the kernel
also never put any blob thing onto that property. And nowadays it
would blow up, e.g. in drm_property_destroy. Also it makes no sense to
return values in an ioctl that only returns metadata about everything.
So let's ditch all the internal code for the blob list, rename the
list to be unambiguous and sprinkle comments all over the place to
explain this peculiar piece of api.

Yet another fallout from not considering DP MST hotplug. With the
previous patches we have stable indices, but it might still happen
that a connector gets added between when we allocate the array and
when we actually add a connector. Especially when we back off due to
ww mutex contention or similar issues.
So store the sizes of the arrays in struct drm_atomic_state and double
check them. We don't really care about races except that we want to
use a consistent value, so ACCESS_ONCE is all we need. And if we
indeed notice that we'd overrun the array then just give up and
restart the entire ioctl.

Otherwise the connector might have been unplugged and destroyed while

didn't consider.
To make sure we get this right add an appropriate WARN_ON to

to clear up). And reorder all the state_clear and backoff calls to

I've totally forgotten that with DP MST connectors can now be
hotplugged. And failed to adapt Rob's drm_atomic_state code (which
predates connector hotplugging) to the new realities.
The first step is to make sure that the connector indices used to
access the arrays of pointers are stable. The connection mutex gives
us enough guarantees for that, which means we won't unecessarily block
on concurrent modesets or background probing.
So add a locking WARN_ON and shuffle the code slightly to make sure we
always hold the right lock.

Well, ttm code wants to process 512 pages at a time for performance.
Memory footprint increased by 512 * sizeof(struct page *) buffer is

Subject: [PATCH] drm/ttm: Avoid memory allocation from shrinker functions.
Commit a91576d7916f6cce ("drm/ttm: Pass GFP flags in order to avoid
deadlock.") caused BUG_ON() due to sc->gfp_mask containing flags
which are not in GFP_KERNEL.
https://bugzilla.kernel.org/show_bug.cgi?id=87891
Changing from sc->gfp_mask to (sc->gfp_mask & GFP_KERNEL) would
avoid the BUG_ON(), but avoiding memory allocation from shrinker
function is better and reliable fix.
Shrinker function is already serialized by global lock, and
clean up function is called after shrinker function is unregistered.
Thus, we can use static buffer when called from shrinker function
and clean up function.
