There is a mplayer video failure reported with xv.
This is because there is a request to do both plane scaling
and colorkey. Because skl hw doesn't support plane scaling
and colorkey at the same time, request is failed which is expected
behavior.
To make xv operate, this patch allows colorkey continue to work
without using scaler. Then behavior would be similar to platforms
without plane scaler support.

GTT caching was disabled by default on gen8 due to not working with
big pages. Some information suggests that it got fixed, but still
GTT caching has been left disabled by default. Or could be it just
meant that the default was changed to off, and hence the problem
got solved.
Enable GTT caching in the hopes of some performance increase.
Whether or not the big pages issue has been fixed is irrelevant
at this stage since we don't use big pages.
This gives me a 1-2% improvement in xonotic on my BSW. Haven't tried

GEN8_L3SQCREG1 isn't saved in the context (verified by going through

Additionally there's another w/a WaTempDisableDOPClkGating:bdw which

drm/atomic-helpers: Recover full cursor plane behaviour
we've added a hack to atomic helpers to never to vblank waits for
cursor updates through the legacy apis since that's what X expects.
Unfortunately we've (again) forgotten to adjust the transitional
helpers. Do this now.
This fixes regressions for drivers only partially converted over to

Wait a little bit longer, 50mS instead of 20mS, until the driver starts
polling for pen-up. The problematic behavior before this patch is applied
is as follows. The behavior was observed on the STMPE610QTR controller.
Upon a physical pen-down event, the touchscreen reports one set of x-y-p
coordinates and a pen-down event. After that, the pen-up polling is
triggered and since the controller is not ready yet, the polling mistakenly
detects a pen-up event while the physical state is still such that the pen
is down on the touch surface.
The pen-up handling flushes the controller FIFO, so after that, all the
samples in the controller are discarded. The controller becomes ready
shortly after this bogus pen-up handling and does generate again a pen-down
interrupt. This time, the controller contains x-y-p samples which all read
as zero. Since pressure value is zero, this set of samples is effectively
ignored by userland.
In the end, the driver just bounces between pen-down and bogus pen-up
handling, generating no useful results. Fix this by giving the controller a
bit more time before polling it for pen-up.

Joydev is currently thinking some absolute mice are joystick, and that
messes up games in VMware guests, as the cursor typically gets stuck in
the top left corner.
Try to detect the event signature of a VMmouse input device and back off
for such devices. We're still incorrectly detecting, for example, the
VMware absolute USB mouse as a joystick, but adding an event signature
matching also that device would be considerably more risky, so defer that
to a later merge window.

Vijay reported that a loop as simple as ...
while true; do
tc qdisc add dev foo root handle 1: prio
tc filter add dev foo parent 1: u32 match u32 0 0 flowid 1
tc qdisc del dev foo root
rmmod cls_u32
done
... will panic the kernel. Moreover, he bisected the change
apparently introducing it to 78fd1d0ab0 ("netlink: Re-add
locking to netlink_lookup() and seq walker").
The removal of synchronize_net() from the netlink socket
triggering the qdisc to be removed, seems to have uncovered
an RCU resp. module reference count race from the tc API.
Given that RCU conversion was done after e341694e3e ("netlink:
Convert netlink_lookup() to use RCU protected hash table")
which added the synchronize_net() originally, occasion of
hitting the bug was less likely (not impossible though):
When qdiscs that i) support attaching classifiers and,
ii) have at least one of them attached, get deleted, they
invoke tcf_destroy_chain(), and thus call into ->destroy()
handler from a classifier module.
After RCU conversion, all classifier that have an internal
prio list, unlink them and initiate freeing via call_rcu()
deferral.
Meanhile, tcf_destroy() releases already reference to the
tp->ops->owner module before the queued RCU callback handler
has been invoked.
Subsequent rmmod on the classifier module is then not prevented
since all module references are already dropped.
By the time, the kernel invokes the RCU callback handler from
the module, that function address is then invalid.
One way to fix it would be to add an rcu_barrier() to
unregister_tcf_proto_ops() to wait for all pending call_rcu()s
to complete.
synchronize_rcu() is not appropriate as under heavy RCU
callback load, registered call_rcu()s could be deferred
longer than a grace period. In case we don't have any pending
call_rcu()s, the barrier is allowed to return immediately.
Since we came here via unregister_tcf_proto_ops(), there
are no users of a given classifier anymore. Further nested
call_rcu()s pointing into the module space are not being
done anywhere.
Only cls_bpf_delete_prog() may schedule a work item, to
unlock pages eventually, but that is not in the range/context
of cls_bpf anymore.

Currently the IBX transcoder B workarounds are not working correctly.
Well, the HDMI one seems to be working somewhat, but the DP one is
definitely busted.
After a bit of experimentation it looks like the best way to make this
work is first disable the port on transcoder B, and then re-enable it
transcoder A, and immediately disable it again.
We can also clean up the code by noting that we can't be called without
a valid crtc. And also note that port A on ILK does not need the
workaround, so let's check for that one too.

intel_dp.c is a mess with all the checks for different
platform/PCH variants and ports. Try to clean it up by recognizing
the following facts:
- IVB port A, and CPT port B/C/D are always the special cases
- VLV/CHV don't have port A
- Using the same kind of logic everywhere makes things much easier to
parse
So let's move the IVB port A and PCH port B/C/D checks to be done first,
and let the other cases fall through, and always check for these things
using the same logic.

We need to re-init the display hardware when going out of suspend. This
includes:
- Hooking the PCH to the reset logic
- Restoring CDCDLK
- Enabling the DDB power
Among those, only the CDCDLK one is a bit tricky. There's some
complexity in that:
- DPLL0 (which is the source for CDCLK) has two VCOs, each with a set
of supported frequencies. As eDP also uses DPLL0 for its link rate,
once DPLL0 is on, we restrict the possible eDP link rates the chosen
VCO.
- CDCLK also limits the bandwidth available to push pixels.
So, as a first step, this commit restore what the BIOS set, until I can
do more testing.
In case that's of interest for the reviewer, I've unit tested the
function that derives the decimal frequency field:
#include <stdio.h>
#include <stdint.h>
#include <assert.h>
#define ARRAY_SIZE(x) (sizeof(x) / sizeof(*(x)))
static const struct dpll_freq {
unsigned int freq;
unsigned int decimal;
} freqs[] = {
{ .freq = 308570, .decimal = 0b01001100111},
{ .freq = 337500, .decimal = 0b01010100001},
{ .freq = 432000, .decimal = 0b01101011110},
{ .freq = 450000, .decimal = 0b01110000010},
{ .freq = 540000, .decimal = 0b10000110110},
{ .freq = 617140, .decimal = 0b10011010000},
{ .freq = 675000, .decimal = 0b10101000100},
};
static void intbits(unsigned int v)
{
int i;
for(i = 10; i >= 0; i--)
putchar('0' + ((v >> i) & 1));
}
static unsigned int freq_decimal(unsigned int freq /* in kHz */)
{
return (freq - 1000) / 500;
}
static void test_freq(const struct dpll_freq *entry)
{
unsigned int decimal = freq_decimal(entry->freq);
printf("freq: %d, expected: ", entry->freq);
intbits(entry->decimal);
printf(", got: ");
intbits(decimal);
putchar('\n');
assert(decimal == entry->decimal);
}
int main(int argc, char **argv)
{
int i;
for (i = 0; i < ARRAY_SIZE(freqs); i++)
test_freq(&freqs[i]);
return 0;
}
v2:
- Rebase on top of -nightly
- Use (freq - 1000) / 500 for the decimal frequency (Ville)
- Fix setting the enable bit of HSW_NDE_RSTWRN_OPT (Ville)
- Rename skl_display_{resume,suspend} to skl_{init,uninit}_cdclk to
be consistent with the BXT code (Ville)
- Store boot CDCLK in ddi_pll_init (Ville)
- Merge dev_priv's skl_boot_cdclk into cdclk_freq
- Use LCPLL_PLL_LOCK instead of (1 << 30) (Ville)
- Replace various '0' by SKL_DPLL0 to be a bit more explicit that
we're programming DPLL0
- Busy poll the PCU before doing the frequency change. It takes about
3/4 cycles, each separated by 10us, to get the ACK from the CPU
(Ville)
v3:
- Restore dev_priv->skl_boot_cdclk, leaving unification with
dev_priv->cdclk_freq for a later patch (Daniel, Ville)
