ce4bc5ca7c drm/bridge: cdns-dsi: Use video mode and clean up cdns_dsi_mode2cfg()
The driver does all the calculations and programming with video timings
(hftp, hbp, etc.) instead of the modeline values (hsync_start, ...).
Thus it makes sense to use struct videomode instead of struct
drm_display_mode internally.

Switch to videomode and do some cleanups in cdns_dsi_mode2cfg() along
the way.

eea4f89b64 drm/bridge: cdns-dsi: Fix REG_WAKEUP_TIME value
The driver tries to calculate the value for REG_WAKEUP_TIME. However,
the calculation itself is not correct, and to add on it, the resulting
value is almost always larger than the field's size, so the actual
result is more or less random.

According to the docs, figuring out the value for REG_WAKEUP_TIME
requires HW characterization and there's no way to have a generic
algorithm to come up with the value. That doesn't help at all...

However, we know that the value must be smaller than the line time, and,
at least in my understanding, the proper value for it is quite small.
Testing shows that setting it to 1/10 of the line time seems to work
well. All video modes from my HDMI monitor work with this algorithm.

Hopefully we'll get more information on how to calculate the value, and
we can then update this.

e948bcaf7d drm/bridge: cdns-dsi: Adjust mode to negative syncs
The Cadence DSI requires negative syncs from the incoming video signal,
but at the moment that requirement is not expressed in any way. If the
crtc decides to use positive syncs, things break down.

Use the adjusted_mode in atomic_check to set the sync flags to negative
ones.

c92765d52d drm/bridge: cdns-dsi: Drop cdns_dsi_adjust_phy_config()
cdns_dsi_adjust_phy_config() is called from cdns_dsi_check_conf(), which
is called from .atomic_check(). It checks the DSI htotal and adjusts it
to align on the DSI lane boundary by changing hfp and then recalculating
htotal and HS clock rate.

This has a few problems.

First is the fact that the whole thing is not needed: we do not need to
align on the lane boundary. The whole frame is sent in HS mode, and it
is fine if the line's last byte clock tick fills, say, only 2 of the 4
lanes. The next line will just continue from there. Assuming the
DSI timing values have been calculated to match the incoming DPI stream,
and the HS clock is compatible with the DPI pixel clock, the "uneven"
DSI lines will even out when multiple lines are being sent.

But we could do the align, aligning is not a problem as such. However,
adding more bytes to the hfp, as the function currently does, makes the
DSI line time longer, so the function then adjusts the HS clock rate.
This is where things fail: we don't know what rates we can get from the
HS clock, and at least in TI K3 SoC case the rates are quite coarsely
grained. Thus small adjustment to hfp will lead to a big change in HS
clock rate, and things break down.

We could do a loop here, adjusting hfp, adjusting clock, checking clock
rate, adjusting hfp again, etc., but considering that the whole
adjustment shouldn't be needed at all, it's easier to just remove the
function.

Something like this function should be added back later, when adding
burst mode support, but that's a bigger change and I don't think this
function would help that work in any way.

3d97dc02a0 drm/bridge: cdns-dsi: Update htotal in cdns_dsi_mode2cfg()
cdns_dsi_mode2cfg() calculates the dsi timings, but for some reason
doesn't set the htotal based on those timings. It is set only later, in
cdns_dsi_adjust_phy_config().

As cdns_dsi_mode2cfg() is the logical place to calculate it, let's move
it there. Especially as the following patch will remove
cdns_dsi_adjust_phy_config().

bcd6808aff drm/bridge: cdns-dsi: Drop checks that shouldn't be in .mode_valid()
The docs say about mode_valid():

"it is not allowed to look at anything else but the passed-in mode, and
validate it against configuration-invariant hardware constraints"

We're doing a lot more than just looking at the mode. The main issue
here is that we're doing checks based on the pixel clock, before we know
what the pixel clock from the crtc actually is.

So, drop the cdns_dsi_check_conf() call from .mode_valid().

644696a4c4 drm/bridge: cdns-dsi: Remove broken fifo emptying check
The driver checks if "DPI(HFP) > DSI(HSS+HSA+HSE+HBP)", and rejects the
mode if not.

However, testing shows that this doesn't hold at all. I can set the hfp
to very small values, with no errors. The feedback from the HW team also
was that the check is not right, although it's not clear if there's a
way to validate the FIFO emptying.

The check rejects quite a lot of modes, apparently for no good reason,
so drop the check.

a3daf184bd drm/nouveau: Improve message for missing firmware
This is inteded to address concerns that users might get cryptic error
messages or a failure to boot if they set nouveau.config=NvGspRm=0 on
the kernel command line and their gpu requires gsp (Ada or newer).
With this patch, that configuration results in error messages like this:

nouveau 0000:01:00.0: gsp: Failed to load required firmware for device.
nouveau 0000:01:00.0: gsp ctor failed: -22
nouveau 0000:01:00.0: probe with driver nouveau failed with error -22

When nouveau fails to load like this, we still fall back to the generic
framebuffer device, so users will still have limited graphical output.

e0ed674acb drm/nouveau: Remove DRM_NOUVEAU_GSP_DEFAULT config
This option was originally intoduced because the GSP code path was
not well tested and we wanted to leave it up to distros which code path
they shipped by default. By now though, the GSP path is probably better
tested than the old firmware eg. Fedora ships GSP by default and we
generally run CTS on GSP. We've always been GSP-only on Ada and later.

So, this path removes the option and effectively sets the option to
always on. We still fall back to the old firmware if GSP is not found.
This change only affects Turing and Ampere.

Users can still set nouveau.config=NvGspRm=0 on the kernel command line
to force using the old firmware on Turing/Ampere.

27738c3003 drm/nouveau: always set RMDevidCheckIgnore for GSP-RM
Always set the RMDevidCheckIgnore registry key for GSP-RM so that it
will continue support newer variants of already supported GPUs.

GSP-RM maintains an internal list of PCI IDs of GPUs that it supports,
and checks if the current GPU is on this list.  While the actual GPU
architecture (as specified in the BOOT_0/BOOT_42 registers) determines
how to enable the GPU, the PCI ID is used for the product name, e.g.
"NVIDIA GeForce RTX 5090".

Unfortunately, if there is no match, GSP-RM will refuse to initialize,
even if the device is fully supported.  Nouveau will get an error
return code, but by then it's too late.  This behavior may be corrected
in a future version of GSP-RM, but that does not help Nouveau today.

Fortunately, GSP-RM supports an undocumented registry key that tells it
to ignore the mismatch.  In such cases, the product name returned will
be a blank string, but otherwise GSP-RM will continue.

Unlike Nvidia's proprietary driver, Nouveau cannot update to newer
firmware versions to keep up with every new hardware release.  Instead,
we can permanently set this registry key, and GSP-RM will continue
to function the same with known hardware.

6510b62fe9 drm/nouveau: replace snprintf() with scnprintf() in nvkm_snprintbf()
snprintf() returns the number of characters that *would* have been
written, which can overestimate how much you actually wrote to the
buffer in case of truncation. That leads to 'data += this' advancing
the pointer past the end of the buffer and size going negative.

Switching to scnprintf() prevents potential buffer overflows and ensures
consistent behavior when building the output string.

Merge tag 'io_uring-6.17-20250808' of git://git.kernel.dk/linux

Pull io_uring fixes from Jens Axboe:

 - Allow vectorized payloads for send/send-zc - like sendmsg, but
   without the hassle of a msghdr.

 - Fix for an integer wrap that should go to stable, spotted by syzbot.
   Nothing alarming here, as you need to be root to hit this.
   Nevertheless, it should get fixed.

   FWIW, kudos to the syzbot crew for having much nicer reproducers now,
   and with nicely annotated source code as well. This is particularly
   useful as syzbot uses the raw interface rather than liburing,
   historically it's been difficult to turn a syzbot reproducer into a
   meaningful test case. With the recent changes, not true anymore!

There's one fix here for an issue with the CS42L43 where we were
 allocating a single property for client devices as just that property
 rather than a terminated array of properties like we are supposed to.
 We also have an update to the MAINTAINERS file for some Renesas devices.
