Pull sound updates from Takashi Iwai:
"There have been some significant changes in the core side, both for
ALSA and ASoC, while lots of development have been seen in SOF, as
well as many small fixes/improvements for ASoC codecs and platforms.
Below is a highlight in this cycle:
Core:
- The unification of PCM vmalloc buffer allocation helpers into the
standard API
- Clean up of the default PCM mmap handling for vmalloc & SG-buffer
- Fix potential races at ALSA timer open
- A few new PCM API extensions; just preliminary core changes, the
actual changes in drivers will be merged in 5.6
- Continued ASoC componentization works; now almost everything is a
common ASoC component object. A lot of refactoring and
simplification have been done along with it.
ASoC:
- Many fixes to the Sound Open Firmware (SOF) code
- Wake on voice support for Chromebooks
- SPI support and trigger word detection for RT5677
- New drivers for Analog Devices ADAU7118, Intel Cannonlake systems
with RT1011 and RT5682, Texas Instruments TAS2562 and TAS2770
HD-audio:
- Improved Intel DSP configuration / probe code for SOF
- Plumbing the legacy HD-audio driver with Intel SOF HDMI
- DP-MST support for Nvidia HDMI codecs
- Realtek quirks cleanups and new additions as usual
Others:
- Lots of refactoring and cleanups for FireWire; period-size sharing,
h/w IRQ interval configuration, clock recovery improvements, etc
- USB-audio: Scarlett mixer quirks
- Cleanups of PCM calls in various drivers (including media and USB)
to adapt the core API changes"

In the case of a report zones command failure, instead of simply printing
the host_byte and driver_byte values returned, print a message that is more
human readable and useful, adding sense codes too.
To do so, use the already defined sd_print_sense_hdr() and
sd_print_result() functions by moving the declaration of these functions
into sd.h.

When ports are lost due to unzoning them, and the initiator port is
not part of any more zones, the GPN_FT command used for the fabric
scan may fail. In this case, the current code simply gives up after a
few retries. But if the zone is gone, all rports should actually be
marked as lost.
Fix this by jumping to the code that handles logout after GNN_FT after
scan retries are exhausted.

With these performance improvements the generic implementation of

Pull scheduler updates from Ingo Molnar:
"The biggest changes in this cycle were:
- Make kcpustat vtime aware (Frederic Weisbecker)
- Rework the CFS load_balance() logic (Vincent Guittot)
- Misc cleanups, smaller enhancements, fixes.
The load-balancing rework is the most intrusive change: it replaces
the old heuristics that have become less meaningful after the
introduction of the PELT metrics, with a grounds-up load-balancing
algorithm.
As such it's not really an iterative series, but replaces the old
load-balancing logic with the new one. We hope there are no
performance regressions left - but statistically it's highly probable
that there *is* going to be some workload that is hurting from these
chnages. If so then we'd prefer to have a look at that workload and
fix its scheduling, instead of reverting the changes"

Actually sending those commands bring the device to an unrecoverable

The only apparent reason for the PCI_MSI_IRQ_DOMAIN architecture
whitelist was that it requires msi.h. Now that msi.h is mandatory in
asm-generic/Kbuild, every arch should have at least the default version,
so remove the whitelist.
Built for all the architectures that play nice with make.cross, but not
boot tested anywhere.

When a driver enables MSI-X, msix_program_entries() reads the MSI-X Vector
Control register for each vector and saves it in desc->masked. Each
register is 32 bits and bit 0 is the actual Mask bit.
When we restored these registers during resume, we previously set the Mask
bit if *any* bit in desc->masked was set instead of when the Mask bit
itself was set:
pci_restore_state
pci_restore_msi_state
__pci_restore_msix_state
for_each_pci_msi_entry
msix_mask_irq(entry, entry->masked) <-- entire u32 word
__pci_msix_desc_mask_irq(desc, flag)
mask_bits = desc->masked & ~PCI_MSIX_ENTRY_CTRL_MASKBIT
if (flag) <-- testing entire u32, not just bit 0
mask_bits |= PCI_MSIX_ENTRY_CTRL_MASKBIT
writel(mask_bits, desc_addr + PCI_MSIX_ENTRY_VECTOR_CTRL)
This means that after resume, MSI-X vectors were masked when they shouldn't
be, which leads to timeouts like this:
nvme nvme0: I/O 978 QID 3 timeout, completion polled
On resume, set the Mask bit only when the saved Mask bit from suspend was
set.
This should remove the need for 19ea025e1d28 ("nvme: Add quirk for Kingston
NVME SSD running FW E8FK11.T").

27e20603c54b ("PCI/MSI: Move D0 check into pci_msi_check_device()")
moved the power state check into pci_msi_check_device(), which was
subsequently renamed to pci_msi_supported(). This didn't change the
behavior, since both callers checked the power state.
However, it doesn't fit the current "pci_msi_supported()" name, which
should return what the device is capable of, independent of the power
state.
Move the power state check back into the callers for readability. No
functional change intended.

If an error occurs on one of the ios used for creating an
association, the creating routine has error paths that are
invoked by the command failure and the error paths will free
up the controller resources created to that point.
But... the io was ultimately determined by an asynchronous
completion routine that detected the error and which
unconditionally invokes the error_recovery path which calls
delete_association. Delete association deletes all outstanding
io then tears down the controller resources. So the
create_association thread can be running in parallel with
the error_recovery thread. What was seen was the LLDD received
a call to delete a queue, causing the LLDD to do a free of a
resource, then the transport called the delete queue again
causing the driver to repeat the free call. The second free
routine corrupted the allocator. The transport shouldn't be
making the duplicate call, and the delete queue is just one
of the resources being freed.
To fix, it is realized that the create_association path is
completely serialized with one command at a time. So the
failed io completion will always be seen by the create_association
path and as of the failure, there are no ios to terminate and there
is no reason to be manipulating queue freeze states, etc.
The serialized condition stays true until the controller is
transitioned to the LIVE state. Thus the fix is to change the
error recovery path to check the controller state and only
invoke the teardown path if not already in the CONNECTING state.

We've seen a few devices that return different controller id's to
the Fabric Connect command vs the Identify(controller) command. It's
currently hard to identify this failure by existing error messages. It
comes across as a (re)connect attempt in the transport that fails with
a -22 (-EINVAL) status. The issue is compounded by older kernels not
having the controller id check or had the identify command overwrite the
fabrics controller id value before it checked. Both resulted in cases
where the devices appeared fine until more recent kernels.
Clarify the reject by adding an error message on controller id mismatches.

In nvme-fc: it's possible to have connected active controllers
and as no references are taken on the LLDD, the LLDD can be
unloaded. The controller would enter a reconnect state and as
long as the LLDD resumed within the reconnect timeout, the
controller would resume. But if a namespace on the controller
is the root device, allowing the driver to unload can be problematic.
To reload the driver, it may require new io to the boot device,
and as it's no longer connected we get into a catch-22 that
eventually fails, and the system locks up.
Fix this issue by taking a module reference for every connected
controller (which is what the core layer did to the transport
module). Reference is cleared when the controller is removed.

Be less pessimistic about estimated page table use for KFD. Most
allocations use 2MB pages and therefore need less VRAM for page
tables. This allows more VRAM to be used for applications especially
on large systems with many GPUs and hundreds of GB of system memory.
Example: 8 GPUs with 32GB VRAM each + 256GB system memory = 512GB
Old page table reservation per GPU: 1GB
New page table reservation per GPU: 32MB

nvme_loop_create_io_queues() preallocates a big buffer for the IO SGL based
on SG_CHUNK_SIZE.
Modern DMA engines are often capable of dealing with very big segments so
the SG_CHUNK_SIZE is often too big. SG_CHUNK_SIZE results in a static 4KB
SGL allocation per command.
If a controller has lots of deep queues, preallocation for the sg list can
consume substantial amounts of memory. For nvmet-loop, nr_hw_queues can be
128 and each queue's depth 128. This means the resulting preallocation
for the data SGL is 128*128*4K = 64MB per controller.
Switch to runtime allocation for SGL for lists longer than 2 entries. This
is the approach used by NVMe PCI so it should be reasonable for NVMeOF as
well. Runtime SGL allocation has always been the case for the legacy I/O
path so this is nothing new.

use the inline SG and for the bigger IOs the allocation of a bigger SGL

Removes the branching for edge-case where no SCSI device handler
exists. The __map_bio_fast() method was far too limited, by only
selecting a new pathgroup or path IFF there was a path failure, fix this
be eliminating it in favor of __map_bio(). __map_bio()'s extra SCSI
device handler specific MPATHF_PG_INIT_REQUIRED test is not in the fast
path anyway.
This change restores full path selector functionality for bio-based
configurations that don't haave a SCSI device handler. But it should be
noted that the path selectors do have an impact on performance for
certain networks that are extremely fast (and don't require frequent
switching).
