[ Upstream commit 24171a5a4a952c26568ff0d2a0bc8c4708a95e1d ]
With large values of CONFIG_NR_CPUS, three Intel ethernet drivers fail to
compile like:
In function ‘i40e_free_q_vector’,
inlined from ‘i40e_vsi_alloc_q_vectors’ at drivers/net/ethernet/intel/i40e/i40e_main.c:12112:3:
571 | _compiletime_assert(condition, msg, __compiletime_assert_, __COUNTER__)
include/linux/rcupdate.h:1084:17: note: in expansion of macro ‘BUILD_BUG_ON’
1084 | BUILD_BUG_ON(offsetof(typeof(*(ptr)), rhf) >= 4096); \
drivers/net/ethernet/intel/i40e/i40e_main.c:5113:9: note: in expansion of macro ‘kfree_rcu’
5113 | kfree_rcu(q_vector, rcu);
| ^~~~~~~~~
The problem is that the 'rcu' member in 'q_vector' is too far from the start
of the structure. Move this member before the CPU mask instead, in all three
drivers.

LLM Generated explanations, may be completely bogus:
**YES**
This commit should be backported to stable kernel trees for the
following reasons:
1. **Compilation Failure Fix**: This fixes a build-time compilation
failure that occurs with large values of CONFIG_NR_CPUS. The error
prevents the kernel from building successfully, which is a
significant issue for systems configured with high CPU counts.
2. **Root Cause**: The issue stems from the `kfree_rcu()` macro in
`include/linux/rcupdate.h:1084` which includes a
`BUILD_BUG_ON(offsetof(typeof(*(ptr)), rhf) >= 4096)` check. This
compile-time assertion ensures that the RCU head field is within the
first 4096 bytes of the structure.
3. **Simple and Safe Fix**: The fix is straightforward - it moves the
`struct rcu_head rcu` member earlier in the structure, placing it
before the `cpumask_t affinity_mask` member. This is a safe change
because:
- It only reorders structure members
- The RCU head doesn't need to be at any specific location
functionally
- Moving it earlier reduces the offset from the structure start
- No functional code changes are required
4. **Affects Multiple Drivers**: The issue affects three Intel ethernet
drivers (i40e, ixgbe, fm10k), all of which are fixed identically by
moving the rcu member earlier in their respective q_vector
structures.
5. **Configuration-Dependent Bug**: This bug only manifests with large
CONFIG_NR_CPUS values (likely >= 512 or higher), where the
`cpumask_t` type becomes large enough to push the rcu member beyond
the 4096-byte offset limit. Systems with high core counts are
becoming more common in production environments.
6. **No Risk of Regression**: The change is minimal and doesn't alter
any functionality. It's purely a structural reordering that maintains
all existing behavior while fixing the compilation issue.
7. **Meets Stable Criteria**: This fix clearly meets the stable kernel
criteria as it:
- Fixes a real bug (compilation failure)
- Is minimal and contained
- Has no risk of introducing new issues
- Affects users with legitimate configurations
The commit is an excellent candidate for stable backporting as it fixes
a real compilation issue that prevents kernel builds on systems with
large CPU counts, and the fix is trivial with no risk of regression.

LLM Generated explanations, may be completely bogus:
**YES**
This commit should be backported to stable kernel trees. Here's my
extensive analysis:
## Nature of the Change
This commit adds a simple DMI (Desktop Management Interface) quirk entry
for the HP Victus Gaming Laptop 15-fb1xxx model to enable internal
microphone support. The change is:
- Adding a new entry to the `yc_acp_quirk_table[]` array
- The entry matches DMI_BOARD_VENDOR "HP" and DMI_PRODUCT_NAME "Victus
by HP Gaming Laptop 15-fb1xxx"
- Associates the match with `&acp6x_card` driver data
## Comparison with Similar Commits
All 5 similar commits with "Backport Status: YES" follow the exact same
pattern:
1. They add DMI entries for HP laptops (HP OMEN, HP Victus) or other
brands
2. They enable internal microphone functionality for specific hardware
models
3. They are minimal, self-contained changes adding only DMI match
entries
4. They fix hardware enablement issues that affect users
## Backport Suitability Analysis
**Reasons this qualifies for stable backporting:**
1. **Bug Fix**: This fixes a hardware functionality issue where the
internal microphone doesn't work on HP Victus 15-fb1xxx laptops
without this quirk
2. **User Impact**: Without this patch, users of this specific laptop
model cannot use their internal microphone, which is a significant
functionality regression
3. **Minimal Risk**: The change is:
- Extremely localized (only adds one DMI entry)
- Cannot affect other hardware (DMI matching is specific to this
model)
- Uses the same pattern as dozens of other entries in the same table
- No algorithmic changes or new features
4. **Self-Contained**: The patch is completely self-contained with no
dependencies on other changes
5. **Hardware Enablement**: This falls under the stable tree criteria
for "hardware that is broken by design and needs a quirk"
6. **Precedent**: The git history shows numerous similar DMI quirk
additions for this driver have been backported to stable
## Code Safety Analysis
The code change is safe because:
- It only adds a static data structure entry
- The DMI matching system is well-established and reliable
- The `acp6x_card` driver data is already used by many other entries
- No memory allocations, no new logic paths, no behavioral changes for
existing hardware
This is a textbook example of a stable-appropriate patch: it fixes a
real user-facing bug with minimal risk and follows established patterns.

[ Upstream commit 40b1c2f9b299295ed0482e1fee6f46521e6e79e5 ]
The Lenovo Yoga Book 9i GenX has the wrong values in the cirrus,dev-index
_DSD property. Add a fixup for this model to ignore the property and
hardcode the index from the I2C bus address.
The error in the cirrus,dev-index property would prevent the second amp
instance from probing. The component binding would never see all the
required instances and so there would not be a binding between
patch_realtek.c and the cs35l56 driver.

LLM Generated explanations, may be completely bogus:
Now let me analyze the actual changes in the current commit more
carefully. The commit adds:
1. A fixup function for the Yoga Book 9i GenX that hardcodes the device
index based on I2C address
2. A fixup table mechanism to apply platform-specific workarounds
3. Modified the cs35l56_hda_read_acpi function to apply fixups before
reading the device index
**Analysis and Backport Decision: YES**
This commit should be backported to stable kernel trees for the
following reasons:
1. **Fixes a real bug affecting users**: The commit fixes a hardware
initialization failure on the Lenovo Yoga Book 9i GenX laptop where
the second amplifier would fail to probe due to incorrect cirrus,dev-
index values in the ACPI _DSD property. This prevents audio from
working properly on this device.
2. **Small and contained fix**: The changes are minimal and localized
to:
- Adding a platform-specific fixup function that maps I2C addresses
to correct device indices
- Adding infrastructure to apply platform fixups
- Modifying the initialization flow to check for fixups before
reading ACPI properties
3. **Low regression risk**:
- The fixup only applies to one specific laptop model (17AA390B)
- The fixup infrastructure is designed to be non-invasive - it only
activates for specific subsystem IDs
- The changes don't affect the behavior for any other devices
4. **Follows stable kernel criteria**:
- Fixes a real bug that bothers people (audio not working on a
consumer laptop)
- The fix is obviously correct and tested (reported by a user and has
a bug report)
- Small change (adds ~60 lines, mostly the fixup infrastructure)
- No new features, just a workaround for broken firmware
5. **Similar to previously backported commits**: Looking at the
historical commits, we see that:
- Commit 91191a6e50a2 ("ALSA: hda: cs35l56: Don't use the device
index as a calibration index") was marked as backport-worthy (YES)
and addressed a similar issue with device index handling
- Multiple commits adding quirks for Lenovo devices with
CS35L41/CS35L56 have been backported (marked YES)
6. **Hardware enablement**: This falls into the category of hardware
enablement fixes which are generally considered appropriate for
stable kernels when they fix broken hardware without risking existing
functionality.
The commit message clearly indicates this is fixing a specific hardware
issue where "The error in the cirrus,dev-index property would prevent
the second amp instance from probing" which would result in no audio
binding and broken audio on this laptop model.

Add an optional dependency on SND_SOC_SOF_INTEL_COMMON, to ensure that whenever
the SOF support is in a loadable module, none of the board code can be built-in.
This may be be a little heavy-handed, but I also don't see a reason why one would
want the boards to be built-in but not the SoC, so it shouldn't actually cause
any usability problems.

LLM Generated explanations, may be completely bogus:
Based on my analysis of the commit and its context, here is my
assessment:
**YES** - This commit should be backported to stable kernel trees.
## Extensive Explanation:
### 1. **The commit fixes a critical build failure**
The commit addresses link errors that occur when Intel ASoC board
drivers are built-in (=y) while the SOF core module is built as a
loadable module (=m). The error messages show undefined references to
SOF DAI functions:
- `sof_dai_get_mclk`
- `sof_dai_get_bclk`
- `sof_dai_get_tdm_slots`
These functions are exported from the `snd-sof` module (defined in
`sound/soc/sof/sof-audio.c`), but when board drivers are built-in, they
cannot reference symbols from loadable modules.
### 2. **The fix is minimal and contained**
The change is a single-line modification to the Kconfig dependency:
```diff
-if SND_SOC_INTEL_MACH
+if SND_SOC_INTEL_MACH && (SND_SOC_SOF_INTEL_COMMON ||
!SND_SOC_SOF_INTEL_COMMON)
```
This clever dependency ensures that when `SND_SOC_SOF_INTEL_COMMON` is
built as a module (=m), the Intel machine drivers cannot be built-in
(=y). The `|| !SND_SOC_SOF_INTEL_COMMON` part allows the machine drivers
to be enabled when SOF support is completely disabled.
### 3. **Similar to previous backported fixes**
Looking at the historical commits:
- Commit `8d0872f6239f` (Similar Commit #1) fixed a similar link failure
for `sof-nau8825` and was backported (YES)
- Commit `f4df4e4042b0` (Similar Commit #4) fixed a similar dependency
issue with SOF IMX and was backported (YES)
Both of these commits addressed build/link failures caused by incorrect
Kconfig dependencies, just like this commit.
### 4. **No risk of regression**
The change only affects build configuration and doesn't modify any
runtime code. It prevents invalid configurations that would fail to
build anyway. As the commit message states: "it shouldn't actually cause
any usability problems" because there's no practical reason to have
board drivers built-in while the SOF core is a module.
### 5. **Meets stable tree criteria**
- Fixes a real bug (build failure)
- Small and contained change
- No new features or architectural changes
- Similar fixes have been backported before
- Low risk of introducing new issues
The commit follows the pattern of other Kconfig dependency fixes in the
Intel ASoC subsystem that have been successfully backported to stable
trees.

LLM Generated explanations, may be completely bogus:
**YES**
This commit should be backported to stable kernel trees. Here's my
extensive analysis:
## Analysis of the Commit
### 1. **Nature of the Change**
The commit adds a DMI (Desktop Management Interface) quirk entry for the
ASUS Vivobook PRO 15X (M6501RM) laptop to enable its internal microphone
functionality. The change is minimal - it simply adds 7 lines to the
`yc_acp_quirk_table[]` array in `sound/soc/amd/yc/acp6x-mach.c`:
```c
+ {
+ .driver_data = &acp6x_card,
+ .matches = {
+ DMI_MATCH(DMI_BOARD_VENDOR, "ASUSTeK COMPUTER
INC."),
+ DMI_MATCH(DMI_PRODUCT_NAME, "M6501RM"),
+ }
+ },
```
### 2. **Impact and Bug Fix Nature**
This is a classic hardware enablement fix that:
- **Fixes a real user-facing bug**: The internal microphone on this
specific laptop model doesn't work without this quirk
- **Has zero functional impact on other systems**: DMI quirks only
activate when the exact hardware match is found
- **Follows an established pattern**: The file contains dozens of
similar DMI quirks for various laptop models
### 3. **Code Context Analysis**
From examining the kernel repository:
- The `yc_acp_quirk_table[]` is used in the `acp6x_probe()` function to
enable DMIC (Digital Microphone) support for AMD Yellow Carp platform
- The driver first tries ACPI methods to detect DMIC capability, but
falls back to DMI quirks for systems that don't properly advertise
this capability
- Without this quirk, the microphone simply won't be detected or
function on the affected laptop model
### 4. **Comparison with Similar Commits**
Looking at the historical patterns:
- **3 out of 5 similar DMI quirk additions were marked for stable**
(commits with "Cc: stable@vger.kernel.org")
- All commits marked "YES" for backporting share these characteristics:
- Fix microphone functionality issues
- Add simple DMI entries
- Have bug reports or user confirmations
- Minimal risk of regression
### 5. **Stable Tree Criteria Evaluation**
This commit meets all the key stable tree criteria:
- ✅ **Fixes a real bug**: Broken microphone functionality
- ✅ **Small and contained**: Only 7 lines added
- ✅ **No side effects**: Only affects the specific laptop model
- ✅ **No architectural changes**: Simple table entry addition
- ✅ **Minimal regression risk**: Cannot affect other hardware
- ✅ **User-reported issue**: Commit message indicates user need
### 6. **Risk Assessment**
The risk is essentially zero because:
- DMI matching is exact - it requires both vendor and product name to
match
- The quirk only enables existing functionality, doesn't modify behavior
- Similar quirks have been added hundreds of times without issues
- The pattern is well-established in this subsystem
### 7. **Additional Considerations**
While this commit doesn't have an explicit "Cc: stable@vger.kernel.org"
tag, this is not unusual for AMD audio quirks. The maintainers often
rely on stable maintainers to pick up these obvious hardware enablement
fixes based on their merit.
This type of hardware enablement fix is exactly what stable kernels
should include - it makes Linux work properly on real hardware that
users have purchased, without any risk to existing functionality.
