With recent kernel, AMDGPU failed to resume after suspend on certain laptop.
Sample log:
-----------
Nov 14 11:52:19 Thinkbook kernel: iommu ivhd0: AMD-Vi: Event logged [ILLEGAL_DEV_TABLE_ENTRY device=0000:06:00.0 pasid=0x00000 address=0x135300000 flags=0x0080]
Nov 14 11:52:19 Thinkbook kernel: AMD-Vi: DTE[0]: 7d90000000000003
Nov 14 11:52:19 Thinkbook kernel: AMD-Vi: DTE[1]: 0000100103fc0009
Nov 14 11:52:19 Thinkbook kernel: AMD-Vi: DTE[2]: 2000000117840013
Nov 14 11:52:19 Thinkbook kernel: AMD-Vi: DTE[3]: 0000000000000000
This is because in resume path, CNTRL[EPHEn] is not set. Fix this by
setting CNTRL[EPHEn] to 1 in resume path if EFR[EPHSUP] is set.
Note
May be better approach is to save the control register in suspend path
and restore it in resume path instead of trying to set indivisual
bits. We will have separate patch for that.

The gpiochip_get_ngpios() uses chip_*() macros to print messages.
However these macros rely on gpiodev to be initialised and set,
which is not the case when called via bgpio_init(). In such a case
the printing messages will crash on NULL pointer dereference.
Replace chip_*() macros by the respective dev_*() ones to avoid
such crash.

In jadard_prepare() a reset pulse is generated with the following
statements (delays ommited for clarity):
gpiod_set_value(jadard->reset, 1); --> Deassert reset
gpiod_set_value(jadard->reset, 0); --> Assert reset for 10ms
gpiod_set_value(jadard->reset, 1); --> Deassert reset
However, specifying second argument of "0" to gpiod_set_value() means to
deassert the GPIO, and "1" means to assert it. If the reset signal is
defined as GPIO_ACTIVE_LOW in the DTS, the above statements will
incorrectly generate the reset pulse (inverted) and leave it asserted
(LOW) at the end of jadard_prepare().
Fix reset behavior by inverting gpiod_set_value() second argument
in jadard_prepare(). Also modify second argument to devm_gpiod_get()
in jadard_dsi_probe() to assert the reset when probing.
Do not modify it in jadard_unprepare() as it is already properly
asserted with "1", which seems to be the intended behavior.

On HCI_OP_RESET command, firmware raises alive interrupt. Driver needs
to wait for this before sending other command. This patch fixes the potential
miss of alive interrupt due to which HCI_OP_RESET can timeout.
Expected flow:
If tx command is HCI_OP_RESET,
1. set data->gp0_received = false
2. send HCI_OP_RESET
3. wait for alive interrupt
Actual flow having potential race:
If tx command is HCI_OP_RESET,
1. send HCI_OP_RESET
1a. Firmware raises alive interrupt here and in ISR
data->gp0_received is set to true
2. set data->gp0_received = false
3. wait for alive interrupt

Many drivers abuse the platform driver/bus system as it provides a
simple way to create and bind a device to a driver-specific set of
probe/release functions. Instead of doing that, and wasting all of the
memory associated with a platform device, here is a "faux" bus that
can be used instead.

pciback 0000:01:00.0: not ready 65535ms after FLR; giving up
After an FLR, pci_dev_wait() waits for the device to become ready. Prior
to d591f6804e7e ("PCI: Wait for device readiness with Configuration RRS"),
it polls PCI_COMMAND until it is something other that PCI_POSSIBLE_ERROR
(~0). If it times out, pci_dev_wait() returns -ENOTTY and
__pci_reset_function_locked() tries the next available reset method.
Typically this is Secondary Bus Reset, which does work, so the MT7922 is
eventually usable.
After d591f6804e7e, if Configuration Request Retry Status Software
Visibility (RRS SV) is enabled, pci_dev_wait() polls PCI_VENDOR_ID until it
is something other than the special 0x0001 Vendor ID that indicates a
completion with RRS status.
When RRS SV is enabled, reads of PCI_VENDOR_ID should return either 0x0001,
i.e., the config read was completed with RRS, or a valid Vendor ID. On the
MT7922, it seems that all config reads after FLR return ~0 indefinitely.
When pci_dev_wait() reads PCI_VENDOR_ID and gets 0xffff, it assumes that's
a valid Vendor ID and the device is now ready, so it returns with success.
After pci_dev_wait() returns success, we restore config space and continue.
Since the MT7922 is not actually ready after the FLR, the restore fails and
the device is unusable.
We considered changing pci_dev_wait() to continue polling if a
PCI_VENDOR_ID read returns either 0x0001 or 0xffff. This "works" as it did
before d591f6804e7e, although we have to wait for the timeout and then fall
back to SBR. But it doesn't work for SR-IOV VFs, which *always* return
0xffff as the Vendor ID.
Mark Mediatek MT7922 WiFi devices to avoid the use of FLR completely. This
will cause fallback to another reset method, such as SBR.

'struct scmi_imx_misc_ctrl_set_in' has a zero length array in the end,
The sizeof will not count 'value[]', and hence Tx size will be smaller
than actual size for Tx,and SCMI firmware will flag this as protocol
error.
Fix this by enlarge the Tx size with 'num * sizeof(__le32)' to count in
the size of data.

When mapping a buffer for DMA via .map_page or .map_sg DMA operations,
there is no need to check the machine frames to be aligned according
to the mapped areas size. All what is needed in these cases is that the
buffer is contiguous at machine level.
So carve out the alignment check from range_straddles_page_boundary()
and move it to a helper called by xen_swiotlb_alloc_coherent() and
xen_swiotlb_free_coherent() directly.

Perhaps unsurprisingly there are some platforms where the GTDT isn't
quite right and the Platforms Timer array overflows the length of the
overall table.
While the recently-added sanity checking isn't wrong, it makes it
impossible to boot the kernel on offending platforms. Try to hobble
along and limit the Platform Timer count to the bounds of the table.

If the XDP program doesn't result in XDP_PASS then we leak the
memory allocated by am65_cpsw_build_skb().
It is pointless to allocate SKB memory before running the XDP
program as we would be wasting CPU cycles for cases other than XDP_PASS.
Move the SKB allocation after evaluating the XDP program result.
This fixes the memleak. A performance boost is seen for XDP_DROP test.

It is possible for some waves in a workgroup to finish their save
sequence before the group leader has had time to capture the workgroup
barrier state. When this happens, having those waves exit do impact the
barrier state. As a consequence, the state captured by the group leader
is invalid, and is eventually incorrectly restored.
This patch proposes to have all waves in a workgroup wait for each other

The destructor of a gtt bo is declared as

Which takes void** as the second parameter.
GCC allows passing void* to the function because void* can be implicitly
casted to any other types, so it can pass compiling.
However, passing this void* parameter into the function's
execution process(which expects void** and dereferencing void**)

The recent platform profile changes prevent the tpacpi platform driver
from registering. This error is seen in the kernel logs, and the
various tpacpi entries are not created:
[ 7550.642171] platform thinkpad_acpi: Resources present before probing
This happens because devm_platform_profile_register() is called before
tpacpi_pdev probes (thanks to Kurt Borja for identifying the root
cause).
For now revert back to the old platform_profile_register to fix the
issue. This is quick fix and will be re-implemented later as more
testing is needed for full solution.
