Here is the 9p patches for the 6.3 merge window combining
the tested and reviewed patches from both Dominique's
for-next tree and my for-next tree. Most of these
patches have been in for-next since December with only
some reword in the description:
- some fixes and cleanup setting up for a larger set
of performance patches I've been working on
- a contributed fixes relating to 9p/rdma
- some contributed fixes relating to 9p/xen
I've marked this as part 1, I'm not sure I'll be
submitting part 2. There were several performance
patches that I wanted to get in, but the revisions
after review only went out last week so while they
have been tested, I haven't received reviews on the
revisions.
Its been about a decade since I've submitted a pull
request, sorry if I messed anything up.

The value shown by power1_max_interval in millisec is essentially:
((1.x * power(2,y)) * 1000) >> 10
Where x and y are read from a HW register. On ATSM, x and y are 0 on
power-up so the value shown is 0.
Writes of 0 to power1_max_interval had previously been disallowed to avoid
computing ilog2(0) but this resulted in the corner-case bug
below. Therefore allow writes of 0 now but special case that write to
x = y = 0.

The test_local_dnat_portonly() function initiates the client-side as
soon as it sets the listening side to the background. This could lead to
a race condition where the server may not be ready to listen. To ensure
that the server-side is up and running before initiating the
client-side, a delay is introduced to the test_local_dnat_portonly()
function.

Grab the HDR DPCD refresh timeout (time we need to wait after
writing the sourc OUI before the HDR DPCD registers are ready)
from the VBT.
Windows doesn't even seem to have any default value for this,
which is perhaps a bit weird since the VBT value is documented
as TGL+ and I thought the HDR backlight stuff might already be
used on earlier platforms. To play it safe I left the old
hardcoded 30ms default in place. Digging through some internal
stuff that seems to have been a number given by the vendor for
one particularly slow TCON. Although I did see 50ms mentioned
somewhere as well.
Let's also include the value in the debug print to ease
debugging, and toss in the customary connector id+name as well.
The TGL Thinkpad T14 I have sets this to 0 btw. So the delay
is now gone on this machine:

When the police was removed from the port, then it was trying to
remove the police from the police id and not from the actual
police index.
The police id represents the id of the police and police index
represents the position in HW where the police is situated.
The port police id can be any number while the port police index
is a number based on the port chip port.
Fix this by deleting the police from HW that is situated at the
police index and not police id.

Remove the bogus csync check and replace it with something that:
- triggers for all forms of csync, not just the basic analog variant
- actually populates the mode csync flags so that drivers can
decide what to do with the mode
Originally the code tried to outright reject csync, but that
apparently broke some bogus LCD monitor that claimed to have
a detailed mode that uses analog csync, despite also claiming
the monitor only support separate sync:
https://bugzilla.redhat.com/show_bug.cgi?id=540024
Potentially that monitor should just be quirked or something.
Anyways, what we are dealing with now is some kind of funny i915
JSL machine with eDP where the panel claims to support a sensible
60Hz separate sync mode, and a 50Hz mode with bipolar analog
csync. The 50Hz mode does not work so we want to not use it.
Easiest way is to just correctly flag it as csync and the driver
will reject it.
TODO: or should we just reject any form of csync (or at least
the analog variants) for digital display interfaces?

The Zbb optimized strncmp has two parts; a fast path that does XLEN/8B
per iteration, and a slow that does one byte per iteration.
The idea is to compare aligned XLEN chunks for most of strings, and do
the remainder tail in the slow path.
The Zbb strncmp has two issues in the fast path:
Incorrect remainder handling (wrong compare): Assume that the string
length is 9. On 64b systems, the fast path should do one iteration,
and one iteration in the slow path. Instead, both were done in the
fast path, which lead to incorrect results. An example:
strncmp("/dev/vda", "/dev/", 5);
Correct by changing "bgt" to "bge".
Missing NULL checks in the second string: This could lead to incorrect
results for:
strncmp("/dev/vda", "/dev/vda\0", 8);
Correct by adding an additional check.

Clang is unable to handle the situation that a chunk of inline
assembly ends with a compat branch instruction and then compiler
generates another control transfer instruction immediately after
this compat branch. The later instruction will end up in forbidden
slot and cause exception.
Workaround by add a option to control the use of compact branch.
Currently it's selected by CC_IS_CLANG and hopefully we can change
it to a version check in future if clang manages to fix it.

add a phandle in the watchdog 'wdt' node. This avoid using arch dependent
operations in driver code.

Watchdog nodes must use 'watchdog' for node name. When a 'make dtbs_check'
is performed the following warning appears:
wdt@100: $nodename:0: 'wdt@100' does not match '^watchdog(@.*|-[0-9a-f])?$'
Fix this warning up properly renaming the node into 'watchdog'.

As vc4_cl_lookup_bos() performs the same steps as drm_gem_objects_lookup(),
replace the open-coded implementation in vc4 to simply use the DRM function.

The array of BOs that are lookup at the start of exec doesn't need
to be instantiated as drm_gem_dma_object, as it doesn't benefit
from its attributes. So, simplify the code by replacing the array of
drm_gem_dma_object for an array of drm_gem_object in the struct
vc4_exec_info.
