We found a hang, the steps to reproduce are as follows:
1. blocking device via scsi_device_set_state()
2. dd if=/dev/sda of=/mnt/t.log bs=1M count=10
3. echo none > /sys/block/sda/queue/scheduler
4. echo "running" >/sys/block/sda/device/state
Step 3 and 4 should complete after step 4, but they hang.

To fix this, we need to run queue before rescanning device when the device
state changes to SDEV_RUNNING.

Complete the enablement of the cm framework feature in the adapter. Perform
the following:
- Detect the presence of the congestion management framework feature.
When the cm framework is present:
- Issue the SET_FEATURE command to enable the feature.
- Register the cm statistics buffer with the adapter.
- Read the cm enablement buffer to determine the cm framework state for cm
management.
When cm management is enabled:
- Monitor all FPIN and congestion signalling events, incrementing
counters.
- Regularly sync with the adapter to communicate congestion events and to
receive an rx request limit.
- Monitor requests for rx data and ensure that no more than the
adapter prescribed limit is issued on the link. If the limit is
exceeded, SCSI and/or NVMe traffic is temporarily suspended.
- Maintain the minute, hourly, daily statistics buffer.
- Monitor for congestion enablement change events, causing a reread of the
enablement buffer and acting on any change in enablement.
And:
- Add teardown logic, including buffer deregistration, on adapter
detachment or reset.

When congestion mgmt is enabled, cmf has the driver regularly issue a
command to synchronize reporting of congestion mgmt events such as fpin and
signal delivery.
This patch adds the definition of the CMF_SYNC WQE and its CQE fields as
well as support for issuing the command. The patch also adds the few
remaining cmf-related SLI additions, such as feature definition for
enablement of CMF and notifications to the driver if the cm enablement mode
changes.

As part of the cmf framework, the firmware maintains a table with
congestion related state information, specifically whether enabled and if
enabled, whether monitoring or actively managing congestion.
Add definition of the table and add support to read the table from the
adapter and determine if it is enabled. In support of this, the READ_OBJECT
mailbox command definition is added to the driver.

The cmf framework requires the driver to maintain a cm statistics table,
accessible inband, of congestion related statistics that are reported per
minute, rolled up to per hour, and rolled up again per day. Several days
worth may be maintained. The table is registered with the adapter when the
MIB feature is enabled.
Add definition of the table and add support to register the table with the
adapter. Includes definition and initialization of event counters that are
later added to the statistics table.

MIB support is currently limited to detecting support in the adapter and
ensuring FDMI support is enabled if present. For the new framework MIB
support also requires active enablement of support via the SET_FEATURES
command with the firmware.
Rework the MIB detection and enablement for the following:
- Move detection away from the get_sli4_parameters routine, and into the
hba_setup path. get_sli4_parameters is only called once at attachment
while hba_setup is called as part of any SLI port reset path. This
ensures detection after firmware download.
- Update SET_FEATURES mbx command for the MIB enablement feature and add
support for the feature.
- Create the cmf_setup routine to encapsulate the detection of MIB support
and perform the enablement of the MIB support feature.

orig_nents should represent the number of entries with pages,
but __sg_alloc_table_from_pages sets orig_nents as the number of
total entries in the table. This is wrong when the API is used for
dynamic allocation where not all the table entries are mapped with
pages. It wasn't observed until now, since RDMA umem who uses this
API in the dynamic form doesn't use orig_nents implicit or explicit
by the scatterlist APIs.
Fix it by changing the append API to track the SG append table
state and have an API to free the append table according to the
total number of entries in the table.
Now all APIs set orig_nents as number of enries with pages.

There are two methods to specify the location of the elf core headers:
using the "elfcorehdr=" kernel parameter, as handled by generic code in
kernel/crash_dump.c, or using the "linux,elfcorehdr" property under the
"/chosen" node in the Device Tree, as handled by architecture-specific
code in arch/arm64/mm/init.c.
Extend support for "linux,elfcorehdr" to all platforms supporting DT by
adding platform-agnostic handling for handling this property to the FDT
core code. This can co-exist safely with the architecture-specific
handling, until the latter has been removed.
This requires moving the call to of_scan_flat_dt() up, as the code
scanning the "/chosen" node now needs to be aware of the values of
"#address-cells" and "#size-cells".

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.
Fixes: 5706cb3c910c ("drm/amdgpu: fix checking pmops when PM_SLEEP is not enabled")

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 |
| | | |
+-------------+----------------------------+
|Clock feedback | |
|divider max | 128 | 100 |
|cap value | | |
| | | |
| | | |
+------------------------------------------+
|ref_div_max | | |
| | 42 | 20 |
| | | |
| | | |
+------------------------------------------+
|ref_div | 42 | 20 |
| | | |
+------------------------------------------+
|fb_div | 10326 | 8195 |
+------------------------------------------+
|fb_div | 1024 | 163 |
+------------------------------------------+
|fb_dev_p | 4 | 9 |
|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:

- Restricting the changes only for OLAND, just to avoid any regression
for other cards.
- Changed unsigned -> unsigned int to make checkpatch quiet.

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.

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.
