MANA supports RDMA in PF mode. The driver should record the doorbell
physical address when in PF mode.
The doorbell physical address is used by the RDMA driver to map
doorbell pages of the device to user-mode applications through RDMA
verbs interface. In the past, they have been mapped to user-mode while
the device is in VF mode. With the support for PF mode implemented,
also expose those pages in PF mode.
Support for PF mode is implemented in

EN7581 SoC allows configuring the size and the number of buffers in
hwfd payload queue for both QDMA0 and QDMA1.
In order to reduce the required DRAM used for hwfd buffers queues and
decrease the memory footprint, differentiate hwfd buffer size for QDMA0
and QDMA1 and reduce hwfd buffer size to 1KB for QDMA1 (WAN) while
maintaining 2KB for QDMA0 (LAN).

The message "Error getting PHY irq. Use polling instead"
is emitted when the mlxbf_gige driver is loaded by the
kernel before the associated gpio-mlxbf driver, and thus
the call to get the PHY IRQ fails since it is not yet
available. The driver probe() must return -EPROBE_DEFER
if acpi_dev_gpio_irq_get_by() returns the same.

After commit 6f110a5e4f99 ("Disable SLUB_TINY for build testing"), which
causes CONFIG_KASAN to be enabled in allmodconfig again, arm64
allmodconfig builds with older versions of clang (15 through 17) show an
instance of -Wframe-larger-than (which breaks the build with
CONFIG_WERROR=y):
drivers/staging/rtl8723bs/core/rtw_security.c:1287:5: error: stack frame size (2208) exceeds limit (2048) in 'rtw_aes_decrypt' [-Werror,-Wframe-larger-than]
1287 | u32 rtw_aes_decrypt(struct adapter *padapter, u8 *precvframe)
| ^
This comes from aes_decipher() being inlined in rtw_aes_decrypt().
Running the same build with CONFIG_FRAME_WARN=128 shows aes_cipher()
also uses a decent amount of stack, just under the limit of 2048:
drivers/staging/rtl8723bs/core/rtw_security.c:864:19: warning: stack frame size (1952) exceeds limit (128) in 'aes_cipher' [-Wframe-larger-than]
864 | static signed int aes_cipher(u8 *key, uint hdrlen,
| ^
-Rpass-analysis=stack-frame-layout only shows one large structure on the
stack, which is the ctx variable inlined from aes128k128d(). A good
number of the other variables come from the additional checks of
fortified string routines, which are present in memset(), which both
aes_cipher() and aes_decipher() use to initialize some temporary
buffers. In this case, since the size is known at compile time, these
additional checks should not result in any code generation changes but
allmodconfig has several sanitizers enabled, which may make it harder
for the compiler to eliminate the compile time checks and the variables
that come about from them.
The memset() calls are just initializing these buffers to zero, so use
'= {}' instead, which is used all over the kernel and does the exact
same thing as memset() without the fortify checks, which drops the stack
usage of these functions by a few hundred kilobytes.

When the GuC fails to load we declare the device wedged. However, the
very first GuC load attempt on GT0 (from xe_gt_init_hwconfig) is done
before the GT1 GuC objects are initialized, so things go bad when the
wedge code attempts to cleanup GT1. To fix this, check the initialization
status in the functions called during wedge.

lan743x_ptp_io_event_clock_get()
Before calling lan743x_ptp_io_event_clock_get(), the 'channel' value
is checked against the maximum value of PCI11X1X_PTP_IO_MAX_CHANNELS(8).
This seems correct and aligns with the PTP interrupt status register
(PTP_INT_STS) specifications.
However, lan743x_ptp_io_event_clock_get() writes to ptp->extts[] with
only LAN743X_PTP_N_EXTTS(4) elements, using channel as an index:
lan743x_ptp_io_event_clock_get(..., u8 channel,...)
{
...
/* Update Local timestamp */
extts = &ptp->extts[channel];
extts->ts.tv_sec = sec;
...
}
To avoid an out-of-bounds write and utilize all the supported GPIO
inputs, set LAN743X_PTP_N_EXTTS to 8.

NIX block can receive packets from multiple links such as
MAC (RPM), LBK and CPT.
-----------------
RPM --| NIX |
-----------------
|
|
LBK
Each link supports multiple channels for example RPM link supports
16 channels. In case of link oversubsribe, NIX will assert backpressure
on receive channels.
The previous patch considered a single channel per link, resulting in
backpressure not being enabled on the remaining channels

Depending on e.g. DT configuration this driver uses a fixed link.
So we shouldn't rely on the user to enable FIXED_PHY, select it in
Kconfig instead. We may end up with a non-functional driver otherwise.

As reported in [1], a platform firmware update that increased the number
of method parameters and forgot to update a least one of its callers,
caused ACPICA to crash due to use-after-free.
Since this a result of a clear AML issue that arguably cannot be fixed
up by the interpreter (it cannot produce missing data out of thin air),
address it by making ACPICA refuse to evaluate a method if the caller
attempts to pass fewer arguments than expected to it.

A kernel panic was reported with the following kernel log:
EDAC igen6: Expected 2 mcs, but only 1 detected.
BUG: unable to handle page fault for address: 000000000000d570
...
Hardware name: Notebook V54x_6x_TU/V54x_6x_TU, BIOS Dasharo (coreboot+UEFI) v0.9.0 07/17/2024
RIP: e030:ecclog_handler+0x7e/0xf0 [igen6_edac]
...
igen6_probe+0x2a0/0x343 [igen6_edac]
...
igen6_init+0xc5/0xff0 [igen6_edac]
...
This issue occurred because one memory controller was disabled by
the BIOS but the igen6_edac driver still checked all the memory
controllers, including this absent one, to identify the source of
the error. Accessing the null MMIO for the absent memory controller
resulted in the oops above.
Fix this issue by reverting the configuration structure to non-const
and updating the field 'res_cfg->num_imc' to reflect the number of
detected memory controllers.

q->gws is not updated atomically with qpd->mapped_gws_queue. If a
runlist is created between pqm_set_gws and update_queue it will
contain a queue which uses GWS in a process with no GWS allocated.

This commit makes two key fixes to SDMA v4.4.2 handling:
1. disable UTC_L1 in sdma_cntl register when stopping SDMA engines
by reading the current value before modifying UTC_L1_ENABLE bit.
2. Ensure UTC_L1_ENABLE is consistently managed by:
- Adding the missing register write when enabling UTC_L1 during start
- Keeping UTC_L1 enabled by default as per hardware requirements
v2: Correct SDMA_CNTL setting (Philip)

Simplify SDMA v4_4_2 queue reset and stop operations by:
1. Removing GET_INST(SDMA0) conversion for ring->me
2. Using the logical instance ID (ring->me) directly
3. Maintaining consistent behavior with other SDMA queue operations
This change aligns with the existing queue handling logic where
ring->me already represents the correct instance identifier.

This commit makes the following improvements to SDMA engine reset handling:
1. Clarifies in the function documentation that instance_id refers to a logical ID
2. Adds conversion from logical to physical instance ID before performing reset
using GET_INST(SDMA0, instance_id) macro
3. Improves error messaging to indicate when a logical instance reset fails
4. Adds better code organization with blank lines for readability
The change ensures proper SDMA engine reset by using the correct physical
instance ID while maintaining the logical ID interface for callers.
V2: Remove harvest_config check and convert directly to physical instance (Lijo)

Userspace currently is offered a range from 0-0xFF but the PWM is
programmed from 0-0xFFFF. This can be limiting to some software
that wants to apply greater granularity.
[HOW]
Convert internally to firmware values only when mapping custom
brightness curves because these are in 0-0xFF range. Advertise full
PWM range to userspace.

[WHY]
These fields are read for the explicit purpose of detecting embedded LTTPRs
(i.e. between host ASIC and the user-facing port), and thus need to
calculate the correct DPCD address offset based on LTTPR count to target
the appropriate LTTPR's DPCD register space with these queries.
[HOW]
Cascaded LTTPRs in a link each snoop and increment LTTPR count when queried
via DPCD read, so an LTTPR embedded in a source device (e.g. USB4 port on a
laptop) will always be addressible using the max LTTPR count seen by the
host. Therefore we simply need to use a recently added helper function to
calculate the correct DPCD address to target potentially embedded LTTPRs
based on the received LTTPR count.
