Calling i915_gem_object_get_dma_address() from the vblank
evade critical section triggers might_sleep().
While we know that we've already pinned the framebuffer
and thus i915_gem_object_get_dma_address() will in fact
not sleep in this case, it seems reasonable to keep the
unconditional might_sleep() for maximum coverage.
So let's instead pre-populate the dma address during
fb pinning, which all happens before we enter the
vblank evade critical section.
We can use u32 for the dma address as this class of
hardware doesn't support >32bit addresses.

Originally, with strict in order execution, we could complete execution
only when the queue was empty. Preempt-to-busy allows replacement of an
active request that may complete before the preemption is processed by
HW. If that happens, the request is retired from the queue, but the
queue_priority_hint remains set, preventing direct submission until
after the next CS interrupt is processed.
This preempt-to-busy race can be triggered by the heartbeat, which will
also act as the power-management barrier and upon completion allow us to
idle the HW. We may process the completion of the heartbeat, and begin
parking the engine before the CS event that restores the
queue_priority_hint, causing us to fail the assertion that it is MIN.

That has been tracked down to be happening when another thread is
deactivating the VMA inside __active_retire() helper, after the VMA's
active counter has been already decremented to 0, but before deactivation
of the VMA's object is reported to the object debugging tool.
We could prevent from that race by serializing i915_active_fini() with
__active_retire() via ref->tree_lock, but that wouldn't stop the VMA from
being used, e.g. from __i915_vma_retire() called at the end of
__active_retire(), after that VMA has been already freed by a concurrent
i915_vma_destroy() on return from the i915_active_fini(). Then, we should
rather fix the issue at the VMA level, not in i915_active.
Since __i915_vma_parked() is called from __gt_park() on last put of the
GT's wakeref, the issue could be addressed by holding the GT wakeref long
enough for __active_retire() to complete before that wakeref is released
and the GT parked.
I believe the issue was introduced by commit d93939730347 ("drm/i915:
Remove the vma refcount") which moved a call to i915_active_fini() from
a dropped i915_vma_release(), called on last put of the removed VMA kref,
to i915_vma_parked() processing path called on last put of a GT wakeref.
However, its visibility to the object debugging tool was suppressed by a
bug in i915_active that was fixed two weeks later with commit e92eb246feb9
("drm/i915/active: Fix missing debug object activation").
A VMA associated with a request doesn't acquire a GT wakeref by itself.
Instead, it depends on a wakeref held directly by the request's active
intel_context for a GT associated with its VM, and indirectly on that
intel_context's engine wakeref if the engine belongs to the same GT as the
VMA's VM. Those wakerefs are released asynchronously to VMA deactivation.
Fix the issue by getting a wakeref for the VMA's GT when activating it,
and putting that wakeref only after the VMA is deactivated. However,
exclude global GTT from that processing path, otherwise the GPU never goes
idle. Since __i915_vma_retire() may be called from atomic contexts, use
async variant of wakeref put. Also, to avoid circular locking dependency,
take care of acquiring the wakeref before VM mutex when both are needed.
v7: Add inline comments with justifications for:
- using untracked variants of intel_gt_pm_get/put() (Nirmoy),
- using async variant of _put(),
- not getting the wakeref in case of a global GTT,
- always getting the first wakeref outside vm->mutex.
v6: Since __i915_vma_active/retire() callbacks are not serialized, storing
a wakeref tracking handle inside struct i915_vma is not safe, and
there is no other good place for that. Use untracked variants of
intel_gt_pm_get/put_async().
v5: Replace "tile" with "GT" across commit description (Rodrigo),
- avoid mentioning multi-GT case in commit description (Rodrigo),
- explain why we need to take a temporary wakeref unconditionally inside
i915_vma_pin_ww() (Rodrigo).
v4: Refresh on top of commit 5e4e06e4087e ("drm/i915: Track gt pm
wakerefs") (Andi),
- for more easy backporting, split out removal of former insufficient
workarounds and move them to separate patches (Nirmoy).
- clean up commit message and description a bit.
v3: Identify root cause more precisely, and a commit to blame,
- identify and drop former workarounds,
- update commit message and description.
v2: Get the wakeref before VM mutex to avoid circular locking dependency,
- drop questionable Fixes: tag.

Since commit 0c65dc062611 ("drm/i915/jsl: s/JSL/JASPERLAKE for
platform/subplatform defines"), boot freezes on a Jasper Lake tablet
(Librem 11), usually with graphical corruption on the eDP display,
but sometimes just a black screen. This commit was included in 6.6 and
later.
That commit was intended to refactor EHL and JSL macros, but the change
to ehl_combo_pll_div_frac_wa_needed() started matching JSL incorrectly
when it was only intended to match EHL.
It replaced:
return ((IS_PLATFORM(i915, INTEL_ELKHARTLAKE) &&

with:
return (((IS_ELKHARTLAKE(i915) || IS_JASPERLAKE(i915)) &&

v2: Keep hardware read under the lock so the whole operation of updating
energy from hardware is still atomic (Guenter),
- instead, acquire the rpm wakeref before the lock and hold it as long

Looks like the undelayed vblank gets signalled exactly when
the active period ends. That is a problem for DSB+VRR when
we are already in vblank and expect DSB to start executing
as soon as we send the push. Instead of starting, the DSB
just keeps on waiting for the undelayed vblank which won't
signal until the end of the next frame's active period,
which is far too late.
The end result is that DSB won't have even started
executing by the time the flips/etc. have completed.
We then wait for an extra 1ms, after which we terminate
the DSB and report a timeout:
[drm] *ERROR* [CRTC:80:pipe A] DSB 0 timed out waiting for idle (current head=0xfedf4000, head=0x0, tail=0x1080)
To fix this let's configure DSB to use the so called VRR
"safe window" instead of the undelayed vblank to trigger
the DSB vblank logic, when VRR is enabled.

Looks like TRANS_CHICKEN bit 31 means something totally different
depending on the platform:
TGL: generate VRR "safe window" for DSB
ADL/DG2: make TRANS_SET_CONTEXT_LATENCY effective with VRR
So far we've only set this on ADL/DG2, but when using DSB+VRR
we also need to set it on TGL.
And a quick test on MTL says it doesn't need this bit for either
of those purposes, even though it's still documented as valid
in bspec.

Reinstate commit 88b065943cb5 ("drm/i915/dsi: Do display on
sequence later on icl+"), for the most part. Turns out some
machines (eg. Chuwi Minibook X) really do need that updated order.
It is also the order the Windows driver uses.
However we can't just undo the revert since that would again
break Lenovo 82TQ. After staring at the VBT sequences for both
machines I've concluded that the Lenovo 82TQ sequences look
somewhat broken:
- INIT_OTP is not present at all
- what should be in INIT_OTP is found in DISPLAY_ON
- what should be in DISPLAY_ON is found in BACKLIGHT_ON
(along with the actual backlight stuff)
The Chuwi Minibook X on the other hand has a full complement
of sequences in its VBT.
So let's try to deal with the broken sequences in the
Lenovo 82TQ VBT by simply swapping the (non-existent)
INIT_OTP sequence with the DISPLAY_ON sequence. Thus we
execute DISPLAY_ON when intending to execute INIT_OTP,
and execute nothing at all when intending to execute
DISPLAY_ON. That should be 100% equivalent to the
revert, for such broken VBTs.

Clearing BSS should only be done once, at the very beginning.
efi_pe_entry() is the entrypoint from the firmware, which may not clear
BSS and so it is done explicitly. However, efi_pe_entry() is also used
as an entrypoint by the mixed mode startup code, in which case BSS will
already have been cleared, and doing it again at this point will corrupt
global variables holding the firmware's GDT/IDT and segment selectors.
So make the memset() conditional on whether the EFI stub is running in
native mode.

Pull more SCSI updates from James Bottomley:
"The vfs has long had a write lifetime hint mechanism that gives the
expected longevity on storage of the data being written. f2fs was the
original consumer of this and used the hint for flash data placement
(mostly to avoid write amplification by placing objects with similar
lifetimes in the same erase block).
More recently the SCSI based UFS (Universal Flash Storage) drivers
have wanted to take advantage of this as well, for the same reasons as
f2fs, necessitating plumbing the write hints through the block layer
and then adding it to the SCSI core.
The vfs write_hints already taken plumbs this as far as block and this
completes the SCSI core enabling based on a recently agreed reuse of
the old write command group number. The additions to the scsi_debug
driver are for emulating this property so we can run tests on it in
the absence of an actual UFS device"

higher address
Following warning is sometimes observed while booting my servers:
[ 3.594838] DMA: preallocated 4096 KiB GFP_KERNEL pool for atomic allocations
[ 3.602918] swapper/0: page allocation failure: order:10, mode:0xcc1(GFP_KERNEL|GFP_DMA), nodemask=(null),cpuset=/,mems_allowed=0-1
...
[ 3.851862] DMA: preallocated 1024 KiB GFP_KERNEL|GFP_DMA pool for atomic allocation
If 'nokaslr' boot option is set, the warning always happens.
On x86, ZONE_DMA is small zone at the first 16MB of physical address
space. When this problem happens, most of that space seems to be used by
decompressed kernel. Thereby, there is not enough space at DMA_ZONE to
meet the request of DMA pool allocation.
The commit 2f77465b05b1 ("x86/efistub: Avoid placing the kernel below
LOAD_PHYSICAL_ADDR") tried to fix this problem by introducing lower
bound of allocation.
But the fix is not complete.
efi_random_alloc() allocates pages by following steps.
1. Count total available slots ('total_slots')
2. Select a slot ('target_slot') to allocate randomly
3. Calculate a starting address ('target') to be included target_slot
4. Allocate pages, which starting address is 'target'
In step 1, 'alloc_min' is used to offset the starting address of memory
chunk. But in step 3 'alloc_min' is not considered at all. As the
result, 'target' can be miscalculated and become lower than 'alloc_min'.
When KASLR is disabled, 'target_slot' is always 0 and the problem
happens everytime if the EFI memory map of the system meets the
condition.
Fix this problem by calculating 'target' considering 'alloc_min'.

Pull USB / Thunderbolt updates from Greg KH:
"Here is the big set of USB and Thunderbolt changes for 6.9-rc1. Lots
of tiny changes and forward progress to support new hardware and
better support for existing devices. Included in here are:
- Thunderbolt (i.e. USB4) updates for newer hardware and uses as more
people start to use the hardware
- default USB authentication mode Kconfig and documentation update to
make it more obvious what is going on
- USB typec updates and enhancements
- usual dwc3 driver updates
- usual xhci driver updates
- function USB (i.e. gadget) driver updates and additions
- new device ids for lots of drivers
- loads of other small updates, full details in the shortlog
All of these, including a "last minute regression fix" have been in
linux-next with no reported issues"

Per filesystems/sysfs.rst, show() should only use sysfs_emit()
or sysfs_emit_at() when formatting the value to be returned to user space.
coccinelle complains that there are still a couple of functions that use
snprintf(). Convert them to sysfs_emit().
