[ Upstream commit 3d5f70949f ]
The Lenovo OneLink+ Dock contains two VL812 USB3.0 controllers:
17ef:1018 upstream
17ef:1019 downstream
Those two controllers both have problems with some USB3.0 devices,
particularly self-powered ones. Typical error messages include:
Timeout while waiting for setup device command
device not accepting address X, error -62
unable to enumerate USB device
By process of elimination the controllers themselves were identified as
the cause of the problem. Through trial and error the issue was solved
by using USB_QUIRK_RESET_RESUME for both chips.

[ Upstream commit 3cf0507625 ]
Move the panel specific VBT parsing to happen during the
output probing stage. Needs to be done because the VBT
parsing will need to look at the EDID to determine
the correct panel_type on some machines.
We split the parsed VBT data (i915->vbt) along the same
boundary. For the moment we just hoist all the panel
specific stuff into connector->panel.vbt since that seems
like the most convenient place for eg. the backlight code.
Note that we simply drop the drrs type check from
intel_drrs_frontbuffer_update() since that operates on the whole
device rather than a specific connector/encoder. But the check
was just a micro optimization so removing it doesn't actually
mattter for correctness.
TODO: Lot's of cleanup to be done in the future. Eg. most of
the DSI stuff could probably be eliminated entirely and just
parsed on demand during DSI init.

commit e22aa14866 upstream.
If we set XFRM security policy by calling setsockopt with option
IPV6_XFRM_POLICY, the policy will be stored in 'sock_policy' in 'sock'
struct. However tcp_v6_send_response doesn't look up dst_entry with the
actual socket but looks up with tcp control socket. This may cause a
problem that a RST packet is sent without ESP encryption & peer's TCP
socket can't receive it.
This patch will make the function look up dest_entry with actual socket,
if the socket has XFRM policy(sock_policy), so that the TCP response
packet via this function can be encrypted, & aligned on the encrypted
TCP socket.
Tested: We encountered this problem when a TCP socket which is encrypted
in ESP transport mode encryption, receives challenge ACK at SYN_SENT
state. After receiving challenge ACK, TCP needs to send RST to
establish the socket at next SYN try. But the RST was not encrypted &
peer TCP socket still remains on ESTABLISHED state.
So we verified this with test step as below.
[Test step]
1. Making a TCP state mismatch between client(IDLE) & server(ESTABLISHED).
2. Client tries a new connection on the same TCP ports(src & dst).
3. Server will return challenge ACK instead of SYN,ACK.
4. Client will send RST to server to clear the SOCKET.
5. Client will retransmit SYN to server on the same TCP ports.
[Expected result]
The TCP connection should be established.

commit 805ce86149 upstream.
The previous patch triggered a build failure for the debian kernel,
which has CONFIG_64BIT enabled, uses the CROSS_COMPILER environment
variable and uses ARCH=parisc to configure the kernel for 64-bit
support.
This patch weakens the previous patch while keeping the recommended way
to configure the kernel with:
ARCH=parisc -> build 32-bit kernel
ARCH=parisc64 -> build 64-bit kernel
while adding the possibility for debian to configure a 64-bit kernel
even if ARCH=parisc is set (PA8X00 CPU has to be selected and
CONFIG_64BIT needs to be enabled).
The downside of this patch is, that we now have a small window open
again where people may get it wrong: if they enable CONFIG_64BIT and try
to compile with a 32-bit compiler.

[ Upstream commit aee5ae7c84 ]
The worker is canceled in gt_park path, but earlier it was assumed that
gt_park path cannot sleep and the cancel is asynchronous. This caused a
race with suspend flow where the worker runs after suspend and causes an
unclaimed register access warning. Cancel the worker synchronously since
the gt_park is indeed allowed to sleep.

[ Upstream commit 59bcdb564b ]
Using two different types of workoads, it was observed that
guc_update_engine_gt_clks was being called too frequently and/or
causing a CPU-to-lmem bandwidth hit over PCIE. Details on
the workloads and numbers are in the notes below.
Background: At the moment, guc_update_engine_gt_clks can be invoked
via one of 3 ways. #1 and #2 are infrequent under normal operating
conditions:
1.When a predefined "ping_delay" timer expires so that GuC-
busyness can sample the GTPM clock counter to ensure it
doesn't miss a wrap-around of the 32-bits of the HW counter.
(The ping_delay is calculated based on 1/8th the time taken
for the counter go from 0x0 to 0xffffffff based on the
GT frequency. This comes to about once every 28 seconds at a
GT frequency of 19.2Mhz).
2.In preparation for a gt reset.
3.In response to __gt_park events (as the gt power management
puts the gt into a lower power state when there is no work
being done).
Root-cause: For both the workloads described farther below, it was
observed that when user space calls IOCTLs that unparks the
gt momentarily and repeats such calls many times in quick succession,
it triggers calling guc_update_engine_gt_clks as many times. However,
the primary purpose of guc_update_engine_gt_clks is to ensure we don't
miss the wraparound while the counter is ticking. Thus, the solution
is to ensure we skip that check if gt_park is calling this function
earlier than necessary.
Solution: Snapshot jiffies when we do actually update the busyness
stats. Then get the new jiffies every time intel_guc_busyness_park
is called and bail if we are being called too soon. Use half of the
ping_delay as a safe threshold.
NOTE1: Workload1: IGTs' gem_create was modified to create a file handle,
allocate memory with sizes that range from a min of 4K to the max supported
(in power of two step-sizes). Its maps, modifies and reads back the
memory. Allocations and modification is repeated until total memory
allocation reaches the max. Then the file handle is closed. With this
workload, guc_update_engine_gt_clks was called over 188 thousand times
in the span of 15 seconds while this test ran three times. With this patch,
the number of calls reduced to 14.
NOTE2: Workload2: 30 transcode sessions are created in quick succession.
While these sessions are created, pcm-iio tool was used to measure I/O
read operation bandwidth consumption sampled at 100 milisecond intervals
over the course of 20 seconds. The total bandwidth consumed over 20 seconds
without this patch was measured at average at 311KBps per sample. With this
patch, the number went down to about 175Kbps which is about a 43% savings.

[ Upstream commit 6463d3930b ]
VPP_WRAP_OSD1_MATRIX_COEF22.Coeff22 is documented as being bits 0-12,
not 16-28.
Without this the output tends to have a pink hue, changing it results
in better color accuracy.
The vendor kernel doesn't use this register. However the code which
sets VIU2_OSD1_MATRIX_COEF22 also uses bits 0-12. There is a slightly
different style of registers for configuring some of the other matrices,
which do use bits 16-28 for this coefficient, but those have names
ending in MATRIX_COEF22_30, and this is not one of those.

[ Upstream commit 8f7115c192 ]
Commit 52824ca450 ("drm/panel-edp: Better describe eDP panel delays")
clarified the various delays used for eDP panels, tying them to the eDP
panel timing diagram.
For Innolux N116BCA-EA1, .prepare_to_enable would be:
t4_min + t5_min + t6_min + max(t7_max, t8_min)
Since t4_min and t5_min are both 0, the panel can use either .enable or
.prepare_to_enable.
As .enable is better defined, switch to using .enable for this panel.
Also add .disable = 50, based on the datasheet's t9_min value. This
effectively makes the delays the same as delay_200_500_e80_d50.
