2f617f4df8 drm/amdkfd: map SVM range with correct access permission
Restore retry fault or prefetch range, or restore svm range after
eviction to map range to GPU with correct read or write access
permission.

Range may includes multiple VMAs, update GPU page table with offset of
prange, number of pages for each VMA according VMA access permission.

ff891a2e64 drm/amdkfd: check access permisson to restore retry fault
Check range access permission to restore GPU retry fault, if GPU retry
fault on address which belongs to VMA, and VMA has no read or write
permission requested by GPU, failed to restore the address. The vm fault

a47f6a5806 drm/amdgpu: Fix build with missing pm_suspend_target_state module export
Building a randconfig here triggered:

  ERROR: modpost: "pm_suspend_target_state" [drivers/gpu/drm/amd/amdgpu/amdgpu.ko] undefined!

because the module export of that symbol happens in
kernel/power/suspend.c which is enabled with CONFIG_SUSPEND.

The ifdef guards in amdgpu_acpi_is_s0ix_supported(), however, test for
CONFIG_PM_SLEEP which is defined like this:

  config PM_SLEEP
          def_bool y
          depends on SUSPEND || HIBERNATE_CALLBACKS

and that randconfig has:

  # CONFIG_SUSPEND is not set
  CONFIG_HIBERNATE_CALLBACKS=y

leading to the module export missing.

Change the ifdeffery to depend directly on CONFIG_SUSPEND.

7301757ea1 drm/amdgpu/OLAND: clip the ref divider max value
This patch limits the ref_div_max value to 100, during the
calculation of PLL feedback reference divider. With current
value (128), the produced fb_ref_div value generates unstable
output at particular frequencies. Radeon driver limits this
value at 100.

On Oland, when we try to setup mode 2048x1280@60 (a bit weird,
I know), it demands a clock of 221270 Khz. It's been observed
that the PLL calculations using values 128 and 100 are vastly
different, and look like this:

+------------------------------------------+
|Parameter    |AMDGPU        |Radeon       |
|             |              |             |

|             |              |             |
|             |              |             |
+------------------------------------------+
|ref_div      |  42          |  20         |
|             |              |             |

|frac fb_de^_p|              |             |
+----------------------------+-------------+

With ref_div_max value clipped at 100, AMDGPU driver can also
drive videmode 2048x1280@60 (221Mhz) and produce proper output
without any blanking and distortion on the screen.

PS: This value was changed from 128 to 100 in Radeon driver also, here:

V2:
- Restricting the changes only for OLAND, just to avoid any regression

- Changed unsigned -> unsigned int to make checkpatch quiet.

V3: Apply the change on SI family (not only oland) (Christian)

a6e6d72295 libnvdimm/labels: Add claim class helpers
In preparation for LIBNVDIMM to manage labels on CXL devices deploy
helpers that abstract the label type from the implementation. The CXL
label format is mostly similar to the EFI label format with concepts /
fields added, like dynamic region creation and label type guids, and
other concepts removed like BLK-mode and interleave-set-cookie ids.

CXL labels do have the concept of a claim class represented by an
"abstraction" identifier. It turns out both label implementations use
the same ids, but EFI encodes them as GUIDs and CXL labels encode them
as UUIDs. For now abstract out the claim class such that the UUID vs
GUID distinction can later be hidden in the helper.

8b03aa0e0e libnvdimm/labels: Add type-guid helpers
In preparation for CXL label support, which does not have the type-guid
concept, wrap the existing users with nsl_set_type_guid, and
nsl_validate_type_guid. Recall that the type-guid is a value in the ACPI
NFIT table to indicate how the memory range is used / should be
presented to upper layers.

de8fa48b9a libnvdimm/labels: Add blk special cases for nlabel and position helpers
In preparation for LIBNVDIMM to manage labels on CXL devices deploy
helpers that abstract the label type from the implementation. The CXL
label format is mostly similar to the EFI label format with concepts /
fields added, like dynamic region creation and label type guids, and
other concepts removed like BLK-mode and interleave-set-cookie ids.

Finish off the BLK-mode specific helper conversion with the nlabel and
position behaviour that is specific to EFI v1.2 labels and not the
original v1.1 definition.

a90ec84837 igc: Add support for PTP getcrosststamp()
i225 supports PCIe Precision Time Measurement (PTM), allowing us to
support the PTP_SYS_OFFSET_PRECISE ioctl() in the driver via the
getcrosststamp() function.

The easiest way to expose the PTM registers would be to configure the PTM
dialogs to run periodically, but the PTP_SYS_OFFSET_PRECISE ioctl()
semantics are more aligned to using a kind of "one-shot" way of retrieving
the PTM timestamps. But this causes a bit more code to be written: the
trigger registers for the PTM dialogs are not cleared automatically.

i225 can be configured to send "fake" packets with the PTM
information, adding support for handling these types of packets is
left for the future.

PTM improves the accuracy of time synchronization, for example, using
phc2sys, while a simple application is sending packets as fast as
possible. First, without .getcrosststamp():

Statistics for this run (total of 2179 lines), in nanoseconds:
  average: 0.14
  stdev: 5.03
  max: 48
  min: -27

For reference, the statistics for runs without PCIe congestion show
that the improvements from enabling PTM are less dramatic. For two
runs of 16466 entries:
  without PTM: avg -0.04 stdev 10.57 max 39 min -42
  with PTM: avg 0.01 stdev 4.20 max 19 min -16

One possible explanation is that when PTM is not enabled, and there's a lot
of traffic in the PCIe fabric, some register reads will take more time
than the others because of congestion on the PCIe fabric.

When PTM is enabled, even if the PTM dialogs take more time to
complete under heavy traffic, the time measurements do not depend on
the time to read the registers.

This was implemented following the i225 EAS version 0.993.

PCIe PTM is similar protocol to PTP (Precision Time Protocol) running

their internal clocks and the correlation with the PCIe root clock.

The i225 NIC exposes some registers that expose those time
measurements, those registers will be used, in later patches, to
implement the PTP_SYS_OFFSET_PRECISE ioctl().

014408cd62 PCI: Add pcie_ptm_enabled()
Add a predicate that returns if PCIe PTM (Precision Time Measurement)
is enabled.

It will only return true if it's enabled in all the ports in the path
from the device to the root.

90e7a6de62 lib/scatterlist: Provide a dedicated function to support table append
RDMA is the only in-kernel user that uses __sg_alloc_table_from_pages to
append pages dynamically. In the next patch. That mode will be extended
and that function will get more parameters. So separate it into a unique
function to make such change more clear.

f674aacd50 spi: sprd: fill offset only to RD_CMD register for reading from slave device
RD_CMD can accept slave address offset only, higher bits are reserved.
Writing the whole slave address including slave base seems unnecessary.

2b961c51f4 spi: sprd: Make sure offset not equal to slave address size
The slave register offset shouldn't equal to the max slave address
which ADI can support to access.

5dc349ec13 spi: sprd: Pass offset instead of physical address to adi_read/_write()
The register offset would be added a physical address base and then pass to
the function sprd_adt_read()/_write() each time before calling them. So we
can do that within these two functions instead, that would make the code
more clear.
