2023-02-13drm: Disable dynamic debug as brokenVille Syrjälä
CONFIG_DRM_USE_DYNAMIC_DEBUG breaks debug prints for (at least modular) drm drivers. The debug prints can be reinstated by manually frobbing /sys/module/drm/parameters/debug after the fact, but at that point the damage is done and all debugs from driver probe are lost. This makes drivers totally undebuggable. There's a more complete fix in progress [1], with further details, but we need this fixed in stable kernels. Mark the feature as broken and disable it by default, with hopes distros follow suit and disable it as well.

2023-02-13cpuidle: psci: Do not suspend topology CPUs on PREEMPT_RTKrzysztof Kozlowski
The runtime Power Management of CPU topology is not compatible with PREEMPT_RT: 1. Core cpuidle path disables IRQs. 2. Core cpuidle calls cpuidle-psci. 3. cpuidle-psci in __psci_enter_domain_idle_state() calls pm_runtime_put_sync_suspend() and pm_runtime_get_sync() which use spinlocks (which are sleeping on PREEMPT_RT). Deep sleep modes are not a priority of Realtime kernels because the latencies might become unpredictable. On the other hand the PSCI CPU idle power domain is a parent of other devices and power domain controllers, thus it cannot be simply skipped (e.g. on Qualcomm SM8250). Disable the idle callbacks in cpuidle-psci and mark the domain as always on. This is a trade-off between making PREEMPT_RT working and still having a proper power domain hierarchy in the system.

2023-02-13selftests: find echo binary to use -ne optionsGuillaume Tucker
Find the actual echo binary using $(which echo) and use it for formatted output with -ne. On some systems, the default echo command doesn't handle the -e option and the output looks like this (arm64 build): -ne Emit Tests for alsa -ne Emit Tests for amd-pstate -ne Emit Tests for arm64 This is for example the case with the KernelCI Docker images e.g. kernelci/gcc-10:x86-kselftest-kernelci. With the actual echo binary (e.g. in /bin/echo), the output is formatted as expected (x86 build this time): Emit Tests for alsa Emit Tests for amd-pstate Skipping non-existent dir: arm64 Only the install target is using "echo -ne" so keep the $ECHO variable local to it.

2023-02-13powercap: intel_rapl: Fix handling for large time windowZhang Rui
When setting the power limit time window, software updates the 'y' bits and 'f' bits in the power limit register, and the value hardware takes follows the formula below Time window = 2 ^ y * (1 + f / 4) * Time_Unit When handling large time window input from userspace, using left shifting breaks in two cases: 1. when ilog2(value) is bigger than 31, in expression "1 << y", left shifting by more than 31 bits has undefined behavior. This breaks 'y'. For example, on an Alderlake platform, "1 << 32" returns 1. 2. when ilog2(value) equals 31, "1 << 31" returns negative value because '1' is recognized as signed int. And this breaks 'f'. Given that 'y' has 5 bits and hardware can never take a value larger than 31, fix the first problem by clamp the time window to the maximum possible value that the hardware can take. Fix the second problem by using unsigned bit left shift. Note that hardware has its own maximum time window limitation, which may be lower than the time window value retrieved from the power limit register. When this happens, hardware clamps the input to its maximum time window limitation. That is why a software clamp is preferred to handle the problem on hand.

2023-02-13block: ublk: check IO buffer based on flag need_get_dataLiu Xiaodong
Currently, uring_cmd with UBLK_IO_FETCH_REQ or UBLK_IO_COMMIT_AND_FETCH_REQ is always checked whether userspace server has provided IO buffer even flag UBLK_F_NEED_GET_DATA is configured. This is a excessive check. If UBLK_F_NEED_GET_DATA is configured, FETCH_RQ doesn't need to provide IO buffer; COMMIT_AND_FETCH_REQ also doesn't need to do that if the IO type is not READ. Check ub_cmd->addr together with ublk_need_get_data() and IO type in ublk_ch_uring_cmd(). With this fix, userspace server doesn't need to preserve buffers for every ublk_io when flag UBLK_F_NEED_GET_DATA is configured, in order to save memory.

2023-02-13sched/core: Fix a missed update of user_cpus_ptrWaiman Long
Since commit 8f9ea86fdf99 ("sched: Always preserve the user requested cpumask"), a successful call to sched_setaffinity() should always save the user requested cpu affinity mask in a task's user_cpus_ptr. However, when the given cpu mask is the same as the current one, user_cpus_ptr is not updated. Fix this by saving the user mask in this case too.

2023-02-13freezer,umh: Fix call_usermode_helper_exec() vs SIGKILLPeter Zijlstra
Tetsuo-San noted that commit f5d39b020809 ("freezer,sched: Rewrite core freezer logic") broke call_usermodehelper_exec() for the KILLABLE case. Specifically it was missed that the second, unconditional, wait_for_completion() was not optional and ensures the on-stack completion is unused before going out-of-scope.

https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers More Qualcomm driver updates for 6.3 The qcom_scm.h file is moved into firmware/qcom, to avoid having any Qualcomm-specific files directly in include/linux. Support for PMIC GLINK is introduced, which on newer Qualcomm platforms provides an interface to the firmware implementing battery management and USB Type-C handling. Together with the base driver comes the custom altmode support driver. SMD RPM gains support for IPQ9574, and socinfo is extended with support for revision 17 of the information format and soc_id for IPQ5332 and IPQ8064 are added. The qcom_stats is changes not to fail when not all parts are initialized. * tag 'qcom-drivers-for-6.3-2' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: soc: qcom: socinfo: Add IDs for IPQ5332 and its variant dt-bindings: arm: qcom,ids: Add IDs for IPQ5332 and its variant dt-bindings: power: qcom,rpmpd: add RPMH_REGULATOR_LEVEL_LOW_SVS_L1 firmware: qcom_scm: Move qcom_scm.h to include/linux/firmware/qcom/ MAINTAINERS: Update qcom CPR maintainer entry dt-bindings: firmware: document Qualcomm SM8550 SCM dt-bindings: firmware: qcom,scm: add qcom,scm-sa8775p compatible soc: qcom: socinfo: Add Soc IDs for IPQ8064 and variants dt-bindings: arm: qcom,ids: Add Soc IDs for IPQ8064 and variants soc: qcom: socinfo: Add support for new field in revision 17 soc: qcom: smd-rpm: Add IPQ9574 compatible soc: qcom: pmic_glink: remove redundant calculation of svid soc: qcom: stats: Populate all subsystem debugfs files dt-bindings: soc: qcom,rpmh-rsc: Update to allow for generic nodes soc: qcom: pmic_glink: add CONFIG_NET/CONFIG_OF dependencies soc: qcom: pmic_glink: Introduce altmode support soc: qcom: pmic_glink: Introduce base PMIC GLINK driver dt-bindings: soc: qcom: Introduce PMIC GLINK binding soc: qcom: dcc: Drop driver for now Link: https://lore.kernel.org/r/20230210182242.2023901-1-andersson@kernel.org Signed-off-by: Arnd Bergmann <arnd@arndb.de>

https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers Qualcomm driver updates for v6.3 This introduces a new driver for the Data Capture and Compare block, which provides a mechanism for capturing hardware state (access MMIO registers) either upon request of triggered automatically e.g. upon a watchdog bite, for post mortem analysis. The remote filesystem memory share driver gains support for having its memory bound to more than a single VMID. The SCM driver gains the minimal support needed to support a new mechanism where secure world can put calls on hold and later request them to be retried. Support for the new SA8775P platform is added to rpmhpd, QDU1000 is added to the SCM driver and a long list of platforms are added to the socinfo driver. Support for socinfo data revision 16 is also introduced.
