2025-04-20ALSA: hda/realtek - Enable speaker for HP platformKailang Yang1-6/+6
The speaker doesn't mute when plugged headphone. This platform support 4ch speakers. The speaker pin 0x14 wasn't fill verb table. After assigned model ALC245_FIXUP_HP_SPECTRE_X360_EU0XXX. The speaker can mute when headphone was plugged.

2025-04-10firmware: cs_dsp: test_bin_error: Fix uninitialized data used as fw versionRichard Fitzgerald4-33/+2
Call cs_dsp_mock_xm_header_get_fw_version() to get the firmware version from the dummy XM header data in cs_dsp_bin_err_test_common_init(). Make the same change to cs_dsp_bin_test_common_init() and remove the cs_dsp_mock_xm_header_get_fw_version_from_regmap() function. The code in cs_dsp_test_bin.c was correctly calling cs_dsp_mock_xm_header_get_fw_version_from_regmap() to fetch the fw version from a dummy header it wrote to XM registers. However in cs_dsp_test_bin_error.c the test doesn't stuff a dummy header into XM, it populates it the normal way using a wmfw file. It should have called cs_dsp_mock_xm_header_get_fw_version() to get the data from its blob buffer, but was calling cs_dsp_mock_xm_header_get_fw_version_from_regmap(). As nothing had been written to the registers this returned the value of uninitialized data. The only other use of cs_dsp_mock_xm_header_get_fw_version_from_regmap() was cs_dsp_test_bin.c, but it doesn't need to use it. It already has a blob buffer containing the dummy XM header so it can use cs_dsp_mock_xm_header_get_fw_version() to read from that.

2025-04-10ASoC: fsl: fsl_qmc_audio: Reset audio data pointers on TRIGGER_START eventHerve Codina1-0/+3
On SNDRV_PCM_TRIGGER_START event, audio data pointers are not reset. This leads to wrong data buffer usage when multiple TRIGGER_START are received and ends to incorrect buffer usage between the user-space and the driver. Indeed, the driver can read data that are not already set by the user-space or the user-space and the driver are writing and reading the same area.

2025-04-06Disable SLUB_TINY for build testingLinus Torvalds2-2/+2
... and don't error out so hard on missing module descriptions. Before commit 6c6c1fc09de3 ("modpost: require a MODULE_DESCRIPTION()") we used to warn about missing module descriptions, but only when building with extra warnigns (ie 'W=1'). After that commit the warning became an unconditional hard error. And it turns out not all modules have been converted despite the claims to the contrary. As reported by Damian Tometzki, the slub KUnit test didn't have a module description, and apparently nobody ever really noticed. The reason nobody noticed seems to be that the slub KUnit tests get disabled by SLUB_TINY, which also ends up disabling a lot of other code, both in tests and in slub itself. And so anybody doing full build tests didn't actually see this failre. So let's disable SLUB_TINY for build-only tests, since it clearly ends up limiting build coverage. Also turn the missing module descriptions error back into a warning, but let's keep it around for non-'W=1' builds.

On systems with >= 1024 cpus (in my case 1152), turbostat fails with the error output: "turbostat: /sys/fs/cgroup/cpuset.cpus.effective: cpu str malformat 0-1151" A similar error appears with the use of turbostat --cpu when the inputted cpu range contains a cpu number >= 1024: # turbostat -c 1100-1151 "--cpu 1100-1151" malformed ... Both errors are caused by parse_cpu_str() reaching its limit of CPU_SUBSET_MAXCPUS. It's a good idea to limit the maximum cpu number being parsed, but 1024 is too low. For a small increase in compute and allocated memory, increasing CPU_SUBSET_MAXCPUS brings support for parsing cpu numbers >= 1024.

2025-04-06kbuild: rpm-pkg: build a debuginfo RPMUday Shankar2-2/+54
The rpm-pkg make target currently suffers from a few issues related to debuginfo: 1. debuginfo for things built into the kernel (vmlinux) is not available in any RPM produced by make rpm-pkg. This makes using tools like systemtap against a make rpm-pkg kernel impossible. 2. debug source for the kernel is not available. This means that commands like 'disas /s' in gdb, which display source intermixed with assembly, can only print file names/line numbers which then must be painstakingly resolved to actual source in a separate editor. 3. debuginfo for modules is available, but it remains bundled with the .ko files that contain module code, in the main kernel RPM. This is a waste of space for users who do not need to debug the kernel (i.e. most users). Address all of these issues by additionally building a debuginfo RPM when the kernel configuration allows for it, in line with standard patterns followed by RPM distributors. With these changes: 1. systemtap now works (when these changes are backported to 6.11, since systemtap lags a bit behind in compatibility), as verified by the following simple test script: # stap -e 'probe kernel.function("do_sys_open").call { printf("%s\n", $$parms); }' dfd=0xffffffffffffff9c filename=0x7fe18800b160 flags=0x88800 mode=0x0 ... 2. disas /s works correctly in gdb, with source and disassembly interspersed: # gdb vmlinux --batch -ex 'disas /s blk_op_str' Dump of assembler code for function blk_op_str: block/blk-core.c: 125 { 0xffffffff814c8740 <+0>: endbr64 127 128 if (op < ARRAY_SIZE(blk_op_name) && blk_op_name[op]) 0xffffffff814c8744 <+4>: mov $0xffffffff824a7378,%rax 0xffffffff814c874b <+11>: cmp $0x23,%edi 0xffffffff814c874e <+14>: ja 0xffffffff814c8768 <blk_op_str+40> 0xffffffff814c8750 <+16>: mov %edi,%edi 126 const char *op_str = "UNKNOWN"; 0xffffffff814c8752 <+18>: mov $0xffffffff824a7378,%rdx 127 128 if (op < ARRAY_SIZE(blk_op_name) && blk_op_name[op]) 0xffffffff814c8759 <+25>: mov -0x7dfa0160(,%rdi,8),%rax 126 const char *op_str = "UNKNOWN"; 0xffffffff814c8761 <+33>: test %rax,%rax 0xffffffff814c8764 <+36>: cmove %rdx,%rax 129 op_str = blk_op_name[op]; 130 131 return op_str; 132 } 0xffffffff814c8768 <+40>: jmp 0xffffffff81d01360 <__x86_return_thunk> End of assembler dump. 3. The size of the main kernel package goes down substantially, especially if many modules are built (quite typical). Here is a comparison of installed size of the kernel package (configured with allmodconfig, dwarf4 debuginfo, and module compression turned off) before and after this patch: # rpm -qi kernel-6.13* | grep -E '^(Version|Size)' Version : 6.13.0postpatch+ Size : 1382874089 Version : 6.13.0prepatch+ Size : 17870795887 This is a ~92% size reduction. Note that a debuginfo package can only be produced if the following configs are set: - CONFIG_DEBUG_INFO=y - CONFIG_MODULE_COMPRESS=n - CONFIG_DEBUG_INFO_SPLIT=n The first of these is obvious - we can't produce debuginfo if the build does not generate it. The second two requirements can in principle be removed, but doing so is difficult with the current approach, which uses a generic rpmbuild script find-debuginfo.sh that processes all packaged executables. If we want to remove those requirements the best path forward is likely to add some debuginfo extraction/installation logic to the modules_install target (controllable by flags). That way, it's easier to operate on modules before they're compressed, and the logic can be reused by all packaging targets.

2025-04-06kconfig: merge_config: use an empty file as initfileDaniel Gomez1-2/+2
The scripts/kconfig/merge_config.sh script requires an existing $INITFILE (or the $1 argument) as a base file for merging Kconfig fragments. However, an empty $INITFILE can serve as an initial starting point, later referenced by the KCONFIG_ALLCONFIG Makefile variable if -m is not used. This variable can point to any configuration file containing preset config symbols (the merged output) as stated in Documentation/kbuild/kconfig.rst. When -m is used $INITFILE will contain just the merge output requiring the user to run make (i.e. KCONFIG_ALLCONFIG=<$INITFILE> make <allnoconfig/alldefconfig> or make olddefconfig). Instead of failing when `$INITFILE` is missing, create an empty file and use it as the starting point for merges.

2025-04-05sh: Align .bss section padding to 8-byte boundaryArtur Rojek1-1/+14
J2-based devices expect to find a device tree blob at the end of the .bss section. As of a77725a9a3c5 ("scripts/dtc: Update to upstream version v1.6.1-19-g0a3a9d3449c8"), libfdt enforces 8-byte alignment for the DTB, causing J2 devices to fail early in sh_fdt_init(). As the J2 loader firmware calculates the DTB location based on the kernel image .bss section size rather than the __bss_stop symbol offset, the required alignment can't be enforced with BSS_SECTION(0, PAGE_SIZE, 8). To fix this, inline a modified version of the above macro which grows .bss by the required size. While this change affects all existing SH boards, it should be benign on platforms which don't need this alignment.

2025-04-04Revert "timekeeping: Fix possible inconsistencies in _COARSE clockids"Thomas Gleixner1-69/+25
This reverts commit 757b000f7b936edf79311ab0971fe465bbda75ea. Miroslav reported that the changes for handling the inconsistencies in the coarse time getters result in a regression on the adjtimex() side. There are two issues: 1) The forwarding of the base time moves the update out of the original period and establishes a new one. 2) The clearing of the accumulated NTP error is changing the behaviour as well. Userspace expects that multiplier/frequency updates are in effect, when the syscall returns, so delaying the update to the next tick is not solving the problem either. Revert the change, so that the established expectations of user space implementations (ntpd, chronyd) are restored. The re-introduced inconsistency of the coarse time getters will be addressed in a subsequent fix.

2025-04-04genirq/migration: Use irqd_get_parent_data() in irq_force_complete_move()Thomas Gleixner1-1/+1
Frank reported, that the common irq_force_complete_move() breaks the out of tree build of ia64. The reason is that ia64 uses the migration code, but does not have hierarchical interrupt domains enabled. This went unnoticed in mainline as both x86 and RISC-V have hierarchical domains enabled. Not that it matters for mainline, but it's still inconsistent. Use irqd_get_parent_data() instead of accessing the parent_data field directly. The helper returns NULL when hierarchical domains are disabled otherwise it accesses the parent_data field of the domain. No functional change.
