gpu: host1x: Remove mid-job CDMA flushes
The current code can issue CDMA flushes (DMAPUT bumps) in the middle
of a job, before all opcodes have been written into the pushbuffer.
This can happen when pushbuffer fills up. Presumably this made sense
at some point in the past, but it doesn't anymore, as it cannot lead
to more space appearing in the pushbuffer as it is only cleaned full
jobs at a time.
Mid-job flushes can also cause problems, as in an extreme situation
(seen in practice), the hardware can run through the entire pushbuffer
including the prefix of a partially written job without the driver
being able to process any CDMA updates. This can cause the engine
MLOCK to be taken and held for extended periods as the tail of the
job is not yet available to hardware.

drm/xe/gsc: do not flush the GSC worker from the reset path
The workqueue used for the reset worker is marked as WQ_MEM_RECLAIM,
while the GSC one isn't (and can't be as we need to do memory
allocations in the gsc worker). Therefore, we can't flush the latter
from the former.
The reason why we had such a flush was to avoid interrupting either
the GSC FW load or in progress GSC proxy operations. GSC proxy
operations fall into 2 categories:
1) GSC proxy init: this only happens once immediately after GSC FW load
and does not support being interrupted. The only way to recover from
an interruption of the proxy init is to do an FLR and re-load the GSC.
2) GSC proxy request: this can happen in response to a request that
the driver sends to the GSC. If this is interrupted, the GSC FW will
timeout and the driver request will be failed, but overall the GSC
will keep working fine.
Flushing the work allowed us to avoid interruption in both cases (unless
the hang came from the GSC engine itself, in which case we're toast
anyway). However, a failure on a proxy request is tolerable if we're in
a scenario where we're triggering a GT reset (i.e., something is already
gone pretty wrong), so what we really need to avoid is interrupting
the init flow, which we can do by polling on the register that reports
when the proxy init is complete (as that ensure us that all the load and
init operations have been completed).
Note that during suspend we still want to do a flush of the worker to
make sure it completes any operations involving the HW before the power
is cut.

In the anx7625_sink_detect(), the device is checked to see

status to the connector. When adding the DP port on port 1 of the

In case of eDP, anx7625_bridge_detect() will not get called because
the bridge->ops condition in anx7625_link_bridge() will not be

- Do not use the array in trace_adjust_address() if there are no
elements
The trace_adjust_address() finds the offset of a module that was
stored in the persistent buffer when reading the previous boot buffer
to see if the address belongs to a module that was loaded in the
previous boot. An array is created that matches currently loaded
modules with previously loaded modules. The trace_adjust_address()
uses that array to find the new offset of the address that's in the
previous buffer. But if no module was loaded, it ends up reading the
last element in an array that was never allocated.
Check if nr_entries is zero and exit out early if it is.
- Remove nested lock of trace_event_sem in print_event_fields()

Camm noticed that on parisc a SIGFPE exception will crash an application with

When the T bit is set, an assist exception trap occurs when when the
co-processor encounters *any* floating-point instruction except for a double
store of register %fr0. The latter cancels all pending traps. Let's fix this
by clearing the Trap (T) bit in the FP status register before returning to the
signal handler in userspace.

provided a fix for SEV-SNP memory acceptance from the EFI stub when

guests running at VMPL >0, as those rely on a SVSM calling area, which
is a shared buffer whose address is programmed into a SEV-SNP MSR, and
the SEV init code that sets up this calling area executes much later
during the boot.
Given that booting via the EFI stub at VMPL >0 implies that the firmware
has configured this calling area already, reuse it for performing memory
acceptance in the EFI stub.

irqchip/qcom-mpm: Prevent crash when trying to handle non-wake GPIOs
On Qualcomm chipsets not all GPIOs are wakeup capable. Those GPIOs do not
have a corresponding MPM pin and should not be handled inside the MPM
driver. The IRQ domain hierarchy is always applied, so it's required to
explicitly disconnect the hierarchy for those. The pinctrl-msm driver marks
these with GPIO_NO_WAKE_IRQ. qcom-pdc has a check for this, but
irq-qcom-mpm is currently missing the check. This is causing crashes when
setting up interrupts for non-wake GPIOs:
root@rb1:~# gpiomon -c gpiochip1 10
irq: IRQ159: trimming hierarchy from :soc@0:interrupt-controller@f200000-1
Unable to handle kernel paging request at virtual address ffff8000a1dc3820
Hardware name: Qualcomm Technologies, Inc. Robotics RB1 (DT)
pc : mpm_set_type+0x80/0xcc
lr : mpm_set_type+0x5c/0xcc
Call trace:
mpm_set_type+0x80/0xcc (P)

gpio_ioctl+0x2d4/0x6c0
Fix this by copying the check for GPIO_NO_WAKE_IRQ from qcom-pdc.c, so that
MPM is removed entirely from the hierarchy for non-wake GPIOs.

the previous update was commit 139caf7ca286 ("drm/i915: Update
DRIVER_DATE to 20201103") 4+ years ago. The DRIVER_DATE has also been
removed altogether.
We've used the DRIVER_TIMESTAMP to log suggestions to file bugs on GPU
hangs when they happen on a driver less than six months old. Combined
with the sporadic DRIVER_TIMESTAMP updates, we really haven't logged the
suggestions for years.
Just stop logging the suggestion to file bugs altogether, and remove
DRIVER_TIMESTAMP. This doesn't really change anything wrt to logging GPU
errors or how we handle bugs. And effectively we already stopped logging
the message a year ago when we stopped updating DRIVER_TIMESTAMP.
Instead, add an unconditional message about the GPU error state
location.
