2025-01-10wifi: wlcore: fix unbalanced pm_runtime callsAndreas Kemnade
If firmware boot failes, runtime pm is put too often: [12092.708099] wlcore: ERROR firmware boot failed despite 3 retries [12092.708099] wl18xx_driver wl18xx.1.auto: Runtime PM usage count underflow!

2025-01-10wifi: wilc1000: unregister wiphy only if it has been registeredAlexis Lothoré
There is a specific error path in probe functions in wilc drivers (both sdio and spi) which can lead to kernel panic, as this one for example when using SPI: Unable to handle kernel paging request at virtual address 9f000000 when read [9f000000] *pgd=00000000 Internal error: Oops: 5 [#1] ARM Modules linked in: wilc1000_spi(+) crc_itu_t crc7 wilc1000 cfg80211 bluetooth ecdh_generic ecc CPU: 0 UID: 0 PID: 106 Comm: modprobe Not tainted 6.13.0-rc3+ #22 Hardware name: Atmel SAMA5 PC is at wiphy_unregister+0x244/0xc40 [cfg80211] LR is at wiphy_unregister+0x1c0/0xc40 [cfg80211] [...] wiphy_unregister [cfg80211] from wilc_netdev_cleanup+0x380/0x494 [wilc1000] wilc_netdev_cleanup [wilc1000] from wilc_bus_probe+0x360/0x834 [wilc1000_spi] wilc_bus_probe [wilc1000_spi] from spi_probe+0x15c/0x1d4 spi_probe from really_probe+0x270/0xb2c really_probe from __driver_probe_device+0x1dc/0x4e8 __driver_probe_device from driver_probe_device+0x5c/0x140 driver_probe_device from __driver_attach+0x220/0x540 __driver_attach from bus_for_each_dev+0x13c/0x1a8 bus_for_each_dev from bus_add_driver+0x2a0/0x6a4 bus_add_driver from driver_register+0x27c/0x51c driver_register from do_one_initcall+0xf8/0x564 do_one_initcall from do_init_module+0x2e4/0x82c do_init_module from load_module+0x59a0/0x70c4 load_module from init_module_from_file+0x100/0x148 init_module_from_file from sys_finit_module+0x2fc/0x924 sys_finit_module from ret_fast_syscall+0x0/0x1c The issue can easily be reproduced, for example by not wiring correctly a wilc device through SPI (and so, make it unresponsive to early SPI commands). It is due to a recent change decoupling wiphy allocation from wiphy registration, however wilc_netdev_cleanup has not been updated accordingly, letting it possibly call wiphy unregister on a wiphy which has never been registered. Fix this crash by moving wiphy_unregister/wiphy_free out of wilc_netdev_cleanup, and by adjusting error paths in both drivers Fixes: fbdf0c5248dc ("wifi: wilc1000: Register wiphy after reading out chipid") Signed-off-by: Alexis Lothoré <alexis.lothore@bootlin.com> Reviewed-by: Marek Vasut <marex@denx.de> Signed-off-by: Kalle Valo <kvalo@kernel.org> Link: https://patch.msgid.link/20241223-wilc_fix_probe_error_path-v1-1-91fa7bd8e5b6@bootlin.com

2025-01-10drm/ttm: Handle cgroup based eviction in TTMMaarten Lankhorst
cgroup resource allocation has to be handled in TTM, so -EAGAIN from cgroups can be converted into -ENOSPC, and the limitcg can be properly evicted in ttm code. When hitting a resource limit through -EAGAIN, the cgroup for which the limit is hit is also returned. This allows eviction to delete only from cgroups which are a subgroup of the current cgroup. The returned CSS is used to determine if eviction is valuable for a given resource, and allows TTM to only target specific resources to lower memory usage.

2025-01-09net: ethernet: ti: cpsw_ale: Fix cpsw_ale_get_field()Sudheer Kumar Doredla
CPSW ALE has 75-bit ALE entries stored across three 32-bit words. The cpsw_ale_get_field() and cpsw_ale_set_field() functions support ALE field entries spanning up to two words at the most. The cpsw_ale_get_field() and cpsw_ale_set_field() functions work as expected when ALE field spanned across word1 and word2, but fails when ALE field spanned across word2 and word3. For example, while reading the ALE field spanned across word2 and word3 (i.e. bits 62 to 64), the word3 data shifted to an incorrect position due to the index becoming zero while flipping. The same issue occurred when setting an ALE entry. This issue has not been seen in practice but will be an issue in the future if the driver supports accessing ALE fields spanning word2 and word3 Fix the methods to handle getting/setting fields spanning up to two words.

2025-01-09scsi: core: Fix command pass through retry regressionMike Christie
scsi_check_passthrough() is always called, but it doesn't check for if a command completed successfully. As a result, if a command was successful and the caller used SCMD_FAILURE_RESULT_ANY to indicate what failures it wanted to retry, we will end up retrying the command. This will cause delays during device discovery because of the command being sent multiple times. For some USB devices it can also cause the wrong device size to be used. This patch adds a check for if the command was successful. If it is we return immediately instead of trying to match a failure.

2025-01-09drm/amdgpu: Fix shift type in amdgpu_debugfs_sdma_sched_mask_set()Dan Carpenter
The "mask" and "val" variables are type u64. The problem is that the BIT() macros are type unsigned long which is just 32 bits on 32bit systems. It's unlikely that people will be using this driver on 32bit kernels and even if they did we only use the lower AMDGPU_MAX_SDMA_INSTANCES (16) bits. So this bug does not affect anything in real life. Still, for correctness sake, u64 bit masks should use BIT_ULL().

testing with clang Commit 24909d9ec7c3 ("drm/amd/display: Overwriting dualDPP UBF values before usage") added a new warning in dml2/display_mode_core.c when building allmodconfig with clang: drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/display_mode_core.c:6268:13: error: stack frame size (3128) exceeds limit (3072) in 'dml_prefetch_check' [-Werror,-Wframe-larger-than] 6268 | static void dml_prefetch_check(struct display_mode_lib_st *mode_lib) | ^ Commit be4e3509314a ("drm/amd/display: DML21 Reintegration For Various Fixes") introduced one in dml2_core/dml2_core_dcn4_calcs.c with the same configuration: drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/dml21/src/dml2_core/dml2_core_dcn4_calcs.c:7236:13: error: stack frame size (3256) exceeds limit (3072) in 'dml_core_mode_support' [-Werror,-Wframe-larger-than] 7236 | static bool dml_core_mode_support(struct dml2_core_calcs_mode_support_ex *in_out_params) | ^ In the case of the first warning, the stack usage was already at the limit at the parent change, so the offending change was rather innocuous. In the case of the second warning, there was a rather dramatic increase in stack usage compared to the parent: drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/dml21/src/dml2_core/dml2_core_dcn4_calcs.c:7032:13: error: stack frame size (2696) exceeds limit (2048) in 'dml_core_mode_support' [-Werror,-Wframe-larger-than] 7032 | static bool dml_core_mode_support(struct dml2_core_calcs_mode_support_ex *in_out_params) | ^ This is an unfortunate interaction between an issue with stack slot reuse in LLVM that gets exacerbated by sanitization (which gets enabled with all{mod,yes}config) and function calls using a much higher number of parameters than is typical in the kernel, necessitating passing most of these values on the stack. While it is possible that there should be source code changes to address these warnings, this code is difficult to modify for various reasons, as has been noted in other changes that have occurred for similar reasons, such as commit 6740ec97bcdb ("drm/amd/display: Increase frame warning limit with KASAN or KCSAN in dml2"). Increase the frame larger than limit when compile testing with clang and the sanitizers enabled to avoid this breakage in all{mod,yes}config, as they are commonly used and valuable testing targets. While it is not the best to hide this issue, it is not really relevant when compile testing, as the sanitizers are commonly stressful on optimizations and they are only truly useful at runtime, which COMPILE_TEST states will not occur with the current build.

2025-01-09hwmon: (acpi_power_meter) Fix uninitialized variablesHuisong Li
The 'power1_alarm' attribute uses the 'power' and 'cap' in the acpi_power_meter_resource structure. Currently, these two fields are just updated when user query 'power' and 'cap' attribute. If user directly query the 'power1_alarm' attribute without queryng above two attributes, driver will use uninitialized variables to judge. So this patch adds the setting of alarm state and update 'cap' in the notification callback and update 'power' and 'cap' if needed to show the real alarm state.

devm_hwmon_device_register_with_info A number of network PHY drivers use the following code: name = devm_hwmon_sanitize_name(dev, dev_name(dev)); if (IS_ERR(name)) return PTR_ERR(name); devm_hwmon_device_register_with_info(dev, name, ..); Make this a generic fallback option and use the device name if no name is provided to devm_hwmon_device_register_with_info().

2025-01-09enic: Fix typo in comment in table indexed by link speedJohn Daley
The RX adaptive interrupt moderation table is indexed by link speed range, where the last row of the table is the catch-all for all link speeds greater than 10Gbps. The comment said 10 - 40Gbps, but since there are now adapters with link speeds than 40Gbps, the comment is now wrong and should indicate it applies to all speeds greater than 10Gbps.

2025-01-09enic: Obtain the Link speed only after the link comes upJohn Daley
The link speed is obtained in the RX adaptive coalescing function. It was being called at probe time when the link may not be up. Change the call to run after the Link comes up. The impact of not getting the correct link speed was that the low end of the adaptive interrupt range was always being set to 0 which could have caused a slight increase in the number of RX interrupts.

2025-01-09spi: zynqmp-gqspi: Support per spi-mem operation frequency switchesMiquel Raynal
Every ->exec_op() call correctly configures the spi bus speed to the maximum allowed frequency for the memory using the constant spi default parameter. Since we can now have per-operation constraints, let's use the value that comes from the spi-mem operation structure instead. In case there is no specific limitation for this operation, the default spi device value will be given anyway. The per-operation frequency capability is thus advertised to the spi-mem core.
