Update the cpufreq store function to use kstrtobool for parsing boolean values. This simplifies the code and improves readability by using a standard kernel function for boolean string conversion. Reviewed-by:

If the `amd-pstate` driver is not loaded automatically by default, it is because the kernel command line parameter has not been added. To resolve this issue, it is necessary to call the `amd_pstate_set_driver()` function to enable the desired mode (passive/active/guided) before registering the driver instance. This ensures that the driver is loaded correctly without relying on the kernel command line parameter. When there is no parameter added to command line, Kernel config will provide the default mode to load. Meanwhile, user can add driver mode in command line which will override the kernel config default option. Reported-by:

The amd-pstate-epp driver has been implemented and resolves the performance drop issue seen in passive mode for shared memory type CPPC systems. Users who enable the active mode driver will not experience a performance drop compared to the passive mode driver. Therefore, the EPP driver should be loaded by default for shared memory type CPPC system to get better performance. Signed-off-by:

To enhance the debugging capability of the driver loading failure for broken CPPC ACPI tables, it can optimize the expression by moving the verification of `min_freq`, `nominal_freq`, and other dependency values to the `amd_pstate_init_freq()` function where they are initialized. If any of these values are incorrect, the `amd-pstate` driver will not be registered. By ensuring that these values are correct before they are used, it will facilitate the debugging process when encountering driver loading failures due to faulty CPPC ACPI tables from BIOS Signed-off-by:

After recent changes in intel_pstate, global.turbo_disabled is only set at the initialization time and never changed. However, it turns out that on some systems the "turbo disabled" bit in MSR_IA32_MISC_ENABLE, the initial state of which is reflected by global.turbo_disabled, can be flipped later and there should be a way to take that into account (other than checking that MSR every time the driver runs which is costly and useless overhead on the vast majority of systems). For this purpose, notice that before the changes in question, store_no_turbo() contained a turbo_is_disabled() check that was used for updating global.turbo_disabled if the "turbo disabled" bit in MSR_IA32_MISC_ENABLE had been flipped and that functionality can be restored. Then, users will be able to reset global.turbo_disabled by writing 0 to no_turbo which used to work before on systems with flipping "turbo disabled" bit. This guarantees the driver state to remain in sync, but READ_ONCE() annotations need to be added in two places where global.turbo_disabled is accessed locklessly, so modify the driver to make that happen. Fixes: 0940f1a8 ("cpufreq: intel_pstate: Do not update global.turbo_disabled after initialization") Closes: https://lore.kernel.org/linux-pm/bf3ebf1571a4788e97daf861eb493c12d42639a3.camel@xry111.siteSuggested-by:

Some of AMD ZEN4 APU/CPU have support for adjusting the CPU core clock more quickly and presicely according to CPU work loading. This is advertised by the Fast CPPC x86 feature. This change will only be effective in the *passive mode* of AMD pstate driver. From the test results of different transition delay values, 600us is chosen to make a balance between performance and power consumption. Some test results on AMD Ryzen 7840HS(Phoenix) APU: 1.

Pull gpio fixes from Bartosz Golaszewski: - interrupt handling and Kconfig fixes for gpio-tqmx86 - add a buffer for storing output values in gpio-tqmx86 as reading back the registers always returns the input values - add missing MODULE_DESCRIPTION()s to several GPIO drivers * tag 'gpio-fixes-for-v6.10-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: gpio: add missing MODULE_DESCRIPTION() macros gpio: tqmx86: fix broken IRQ_TYPE_EDGE_BOTH interrupt type gpio: tqmx86: store IRQ trigger type and unmask status separately gpio: tqmx86: introduce shadow register for GPIO output value gpio: tqmx86: fix typo in Kconfig label

Pull io_uring fixes from Jens Axboe: - Fix a locking order issue with setting max async thread workers (Hagar) - Fix for a NULL pointer dereference for failed async flagged requests using ring provided buffers. This doesn't affect the current kernel, but it does affect older kernels, and is being queued up for 6.10 just to make the stable process easier (me) - Fix for NAPI timeout calculations for how long to busy poll, and subsequently how much to sleep post that if a wait timeout is passed in (me) - Fix for a regression in this release cycle, where we could end up using a partially unitialized match value for io-wq (Su) * tag 'io_uring-6.10-20240607' of git://git.kernel.dk/linux: io_uring: fix possible deadlock in io_register_iowq_max_workers() io_uring/io-wq: avoid garbage value of 'match' in io_wq_enqueue() io_uring/napi: fix timeout calculation io_uring: check for non-NULL file pointer in io_file_can_poll()

Pull btrfs fixes from David Sterba: - fix handling of folio private changes. The private value holds pointer to our extent buffer structure representing a metadata range. Release and create of the range was not properly synchronized when updating the private bit which ended up in double folio_put, leading to all sorts of breakage - fix a crash, reported as duplicate key in metadata, but caused by a race of fsync and size extending write. Requires prealloc target range + fsync and other conditions (log tree state, timing) - fix leak of qgroup extent records after transaction abort * tag 'for-6.10-rc2-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: btrfs: protect folio::private when attaching extent buffer folios btrfs: fix leak of qgroup extent records after transaction abort btrfs: fix crash on racing fsync and size-extending write into prealloc
