2022-09-27drm/amd/pm: use adverse selection for dpm features unsupported by driverEvan Quan
It's vbios and pmfw instead of driver who decide whether some dpm features is supported or not. Driver just de-selects those features which are not permitted on user's request.

2022-09-27x86/alternative: Fix race in try_get_desc()Nadav Amit
I encountered some occasional crashes of poke_int3_handler() when kprobes are set, while accessing desc->vec. The text poke mechanism claims to have an RCU-like behavior, but it does not appear that there is any quiescent state to ensure that nobody holds reference to desc. As a result, the following race appears to be possible, which can lead to memory corruption. CPU0 CPU1 ---- ---- text_poke_bp_batch() -> smp_store_release(&bp_desc, &desc) [ notice that desc is on the stack ] poke_int3_handler() [ int3 might be kprobe's so sync events are do not help ] -> try_get_desc(descp=&bp_desc) desc = __READ_ONCE(bp_desc) if (!desc) [false, success] WRITE_ONCE(bp_desc, NULL); atomic_dec_and_test(&desc.refs) [ success, desc space on the stack is being reused and might have non-zero value. ] arch_atomic_inc_not_zero(&desc->refs) [ might succeed since desc points to stack memory that was freed and might be reused. ] Fix this issue with small backportable patch. Instead of trying to make RCU-like behavior for bp_desc, just eliminate the unnecessary level of indirection of bp_desc, and hold the whole descriptor as a global. Anyhow, there is only a single descriptor at any given moment.

The second perf_event_open() runs concurrently, and during rhltable_lookup() looks up an entry which is being freed: since rhltable_lookup() may run concurrently (under the RCU read lock) with rhltable_remove(), we may end up with a stale entry, for which memory may also have already been freed when being accessed. To fix, only free the failed perf_event after an RCU grace period. This allows subsystems that store references to an event to always access it concurrently under the RCU read lock, even if initialization will fail. Given failure is unlikely and a slow-path, turning the immediate free into a call_rcu()-wrapped free does not affect performance elsewhere.

BlueField-3 SoC has the same I2C IP logic as previous BlueField-1 and 2 SoCs but it has different registers' addresses. This is an effort to keep this driver generic across all BlueField generations. This patch breaks down the "smbus" resource into 3 separate resources to enable us to use common registers' offsets for all BlueField SoCs: struct mlxbf_i2c_resource *timer; struct mlxbf_i2c_resource *mst; struct mlxbf_i2c_resource *slv; Of course, all offsets had to be adjusted accordingly, and we took this chance to reorganize the macros depending on the register block they target. There are only 2 registers' offsets that do not fit within this schema so their offsets are passed as SoC-specific parameters: smbus_master_rs_bytes_off smbus_master_fsm_off Reviewed-by: Khalil Blaiech <kblaiech@nvidia.com> Signed-off-by: Asmaa Mnebhi <asmaa@nvidia.com> Signed-off-by: Wolfram Sang <wsa@kernel.org>

2022-09-27RDMA/mlx5: Don't set tx affinity when lag is in hash modeLiu, Changcheng
In hash mode, without setting tx affinity explicitly, the port select flow table decides which port is used for the traffic. If port_select_flow_table_bypass capability is supported and tx affinity is set explicitly for QP/TIS, they will be added into the explicit affinity table in FW to check which port is used for the traffic. 1. The overloaded explicit affinity table may affect performance. To avoid this, do not set tx affinity explicitly by default. 2. The packets of the same flow need to be transmitted on the same port. Because the packets of the same flow use different QPs in slow & fast path, it shouldn't set tx affinity explicitly for these QPs.

2022-09-27docs/core-api: expand Fedora instructions for GCC pluginsRobert Elliott
In Fedora 36, cross-compiling an allmodconfig configuration for other architectures on x86 fails with this problem: In file included from ../scripts/gcc-plugins/gcc-common.h:95, from ../scripts/gcc-plugins/latent_entropy_plugin.c:78: /usr/lib/gcc/aarch64-linux-gnu/12/plugin/include/builtins.h:23:10: fatal error: mpc.h: No such file or directory 23 | #include <mpc.h> | ^~~~~~~ compilation terminated. In that distro, that header file is available in the separate libmpc-devel package. Although future versions of Fedora might correctly mark that dependency, mention this additional package. To help detect such problems ahead of time, describe the gcc -print-file-name=plugin command that is used by scripts/gcc-plugins/Kconfig to detect plugins [1].
