divvy_up_power() should use weighted_req_power instead of req_power to
calculate granted_power. Otherwise, granted_power may be unexpected as
the denominator total_req_power is a weighted sum.
This is a mistake made during the previous refactor.
Replace req_power with weighted_req_power in divvy_up_power()
calculation.

Move the invocation of intel_pstate_platform_pwr_mgmt_exists() before
checking whether or not HWP is enabled because it does not depend on
any code running before it except for the vendor check and if CPU
performance scaling is going to be carried out by the platform, all of
the code that runs before that function (again, except for the vendor
check) is redundant.
This is not expected to alter any functionality except for the ordering
of messages printed by intel_pstate_init() when it is going to return an
error before attempting to register the driver.

GCC versions below 13 incorrectly detect the copy size as being static and too
small to fit in the "fds" array. Work around this by explicitly calculating the

The mask to select the test-pattern in register ADV748X_SDP_FRP is
incorrect, it's the lower 3 bits which controls the pattern. The
GENMASK() macro is used incorrectly and the generated mask is 0x0e
instead of 0x07.
The result is that not all test patterns are selectable, and that in
some cases the wrong test pattern is activated. Fix this by correcting
the GENMASK().

Extend the generic vDSO data storage with a page for the random state data.
The random state data is stored in a dedicated page, as the existing
storage page is only meant for time-related, time-namespace-aware data.
This simplifies to access logic to not need to handle time namespaces
anymore and also frees up more space in the time-related page.
In case further generic vDSO data store is required it can be added to

On X1E80100, there is a hardware bug in the register logic of the
IRQ_ENABLE_BANK register: While read accesses work on the normal address,
all write accesses must be made to a shifted address. Without a workaround
for this, the wrong interrupt gets enabled in the PDC and it is impossible
to wakeup from deep suspend (CX collapse). This has not caused problems so
far, because the deep suspend state was not enabled. A workaround is
required now since work is ongoing to fix this.
The PDC has multiple "DRV" regions, each one has a size of 0x10000 and
provides the same set of registers for a particular client in the system.
Linux is one the clients and uses DRV region 2 on X1E. Each "bank" inside
the DRV region consists of 32 interrupt pins that can be enabled using the
IRQ_ENABLE_BANK register:
IRQ_ENABLE_BANK[bank] = base + IRQ_ENABLE_BANK + bank * sizeof(u32)
On X1E, this works as intended for read access. However, write access to
most banks is shifted by 2:
IRQ_ENABLE_BANK_X1E[0] = IRQ_ENABLE_BANK[-2]
IRQ_ENABLE_BANK_X1E[1] = IRQ_ENABLE_BANK[-1]
IRQ_ENABLE_BANK_X1E[2] = IRQ_ENABLE_BANK[0] = IRQ_ENABLE_BANK[2 - 2]
IRQ_ENABLE_BANK_X1E[3] = IRQ_ENABLE_BANK[1] = IRQ_ENABLE_BANK[3 - 2]
IRQ_ENABLE_BANK_X1E[4] = IRQ_ENABLE_BANK[2] = IRQ_ENABLE_BANK[4 - 2]
IRQ_ENABLE_BANK_X1E[5] = IRQ_ENABLE_BANK[5] (this one works as intended)
The negative indexes underflow to banks of the previous DRV/client region:
IRQ_ENABLE_BANK_X1E[drv 2][bank 0] = IRQ_ENABLE_BANK[drv 2][bank -2]
= IRQ_ENABLE_BANK[drv 1][bank 5-2]
= IRQ_ENABLE_BANK[drv 1][bank 3]
= IRQ_ENABLE_BANK[drv 1][bank 0 + 3]
IRQ_ENABLE_BANK_X1E[drv 2][bank 1] = IRQ_ENABLE_BANK[drv 2][bank -1]
= IRQ_ENABLE_BANK[drv 1][bank 5-1]
= IRQ_ENABLE_BANK[drv 1][bank 4]
= IRQ_ENABLE_BANK[drv 1][bank 1 + 3]
Introduce a workaround for the bug by matching the qcom,x1e80100-pdc
compatible and apply the offsets as shown above:
- Bank 0...1: previous DRV region, bank += 3
- Bank 1...4: our DRV region, bank -= 2
- Bank 5: our DRV region, no fixup required
The PDC node in the device tree only describes the DRV region for the Linux
client, but the workaround also requires to map parts of the previous DRV
region to issue writes there. To maintain compatibility with old device
trees, obtain the base address of the preceeding region by applying the
-0x10000 offset. Note that this is also more correct from a conceptual
point of view:
It does not really make use of the other region; it just issues shifted
writes that end up in the registers of the Linux associated DRV region 2.

Commit bb9850704c04 ("scsi: ufs: core: Honor runtime/system PM levels if
set by host controller drivers") introduced the check for setting default
PM levels only if the levels are uninitialized by the host controller
drivers. But it missed the fact that the levels could be initialized to 0
(UFS_PM_LVL_0) on purpose by the controller drivers. Even though none of
the drivers are doing so now, the logic should be fixed irrespectively.
So set the default levels unconditionally before calling ufshcd_hba_init()
API which initializes the controller drivers. It ensures that the
controller drivers could override the default levels if required.

After commit 1bad6c4a57ef ("scsi: zero per-cmd private driver data for each
MQ I/O"), the xen-scsifront/virtio_scsi/snic drivers all removed code that
explicitly zeroed driver-private command data.
In combination with commit 464a00c9e0ad ("scsi: core: Kill DRIVER_SENSE"),
after virtio_scsi performs a capacity expansion, the first request will
return a unit attention to indicate that the capacity has changed. And then
the original command is retried. As driver-private command data was not
cleared, the request would return UA again and eventually time out and fail.

This patch implements USB mode setting via a sysfs interface in
cros_ec_typec driver. User-space applications can now change the current
USB mode by writing to "usb_mode" sysfs entry, replacing the previous
ioctl-based method.
The embedded controller (EC) currently supports only entering USB4 mode
and exiting all modes (including altmodes). Both of these operations
trigger Data Reset Message, even if no USB Mode is active.
Additionally, the patch exposes the USB modes supported by the port via
"usb_capability" sysfs attribute.

When doing error injection to some memory DIMMs on certain Intel Emerald
Rapids servers, the i10nm_edac missed error reports for some memory DIMMs.
Certain BIOS configurations may hide some memory controllers, and the
i10nm_edac doesn't enumerate these hidden memory controllers. However, the
ADXL decodes memory errors using memory controller physical indices even
if there are hidden memory controllers. Therefore, the memory controller
physical indices reported by the ADXL may mismatch the logical indices
enumerated by the i10nm_edac, resulting in missed error reports for some
memory DIMMs.
Fix this issue by creating a mapping table from memory controller physical
indices (used by the ADXL) to logical indices (used by the i10nm_edac) and
using it to convert the physical indices to the logical indices during the
error handling process.

gcc-14 produces a bogus warning in some configurations:
drivers/edac/ie31200_edac.c: In function 'ie31200_probe1.isra':
drivers/edac/ie31200_edac.c:412:26: error: 'dimm_info' is used uninitialized [-Werror=uninitialized]
412 | struct dimm_data dimm_info[IE31200_CHANNELS][IE31200_DIMMS_PER_CHANNEL];

412 | struct dimm_data dimm_info[IE31200_CHANNELS][IE31200_DIMMS_PER_CHANNEL];
| ^~~~~~~~~
I don't see any way the unintialized access could really happen here,
but I can see why the compiler gets confused by the two loops.
Instead, rework the two nested loops to only read the addr_decode
registers and then keep only one instance of the dimm info structure.
[Tony: Qiuxu pointed out that the "populate DIMM info" comment was left
behind in the refactor and suggested moving it. I deleted the comment
as unnecessry in front os a call to populate_dimm_info(). That seems
pretty self-describing.]

- to skip watchdog programming through top block if its not present
- fix the setting of WB mask to ensure the WB input control is programmed
correctly through ping-pong
- drop lm_pair for sm6150 as that chipset does not have any 3dmerge block
* Fix the mode validation logic for DP/eDP to account for widebus (2ppc)
to allow high clock resolutions
* Fix to disable dither during encoder disable as otherwise this was
causing kms_writeback failure due to resource sharing between
* WB and DSI paths as DSI uses dither but WB does not
* Fixes for virtual planes, namely to drop extraneous return and fix
uninitialized variables
* Fix to avoid spill-over of DSC encoder block bits when programming
the bits-per-component
* Fixes in the DSI PHY to protect against concurrent access of
PHY_CMN_CLK_CFG regs between clock and display drivers
Core/GPU:
* Fix non-blocking fence wait incorrectly rounding up to 1 jiffy timeout
* Only print GMU fw version once, instead of each time the GPU resumes
