2025-03-19sched/debug: Make CONFIG_SCHED_DEBUG functionality unconditionalIngo Molnar

2025-03-19sched/debug: Change SCHED_WARN_ON() to WARN_ON_ONCE()Ingo Molnar
The scheduler has this special SCHED_WARN() facility that depends on CONFIG_SCHED_DEBUG. Since CONFIG_SCHED_DEBUG is getting removed, convert SCHED_WARN() to WARN_ON_ONCE(). Note that the warning output isn't 100% equivalent: #define SCHED_WARN_ON(x) WARN_ONCE(x, #x) Because SCHED_WARN_ON() would output the 'x' condition as well, while WARN_ONCE() will only show a backtrace. Hopefully these are rare enough to not really matter. If it does, we should probably introduce a new WARN_ON() variant that outputs the condition in stringified form, or improve WARN_ON() itself.

2025-03-19x86/mm: Only do broadcast flush from reclaim if pages were unmappedRik van Riel
Track whether pages were unmapped from any MM (even ones with a currently empty mm_cpumask) by the reclaim code, to figure out whether or not broadcast TLB flush should be done when reclaim finishes. The reason any MM must be tracked, and not only ones contributing to the tlbbatch cpumask, is that broadcast ASIDs are expected to be kept up to date even on CPUs where the MM is not currently active. This change allows reclaim to avoid doing TLB flushes when only clean page cache pages and/or slab memory were reclaimed, which is fairly common. ( This is a simpler alternative to the code that was in my INVLPGB series before, and it seems to capture most of the benefit due to how common it is to reclaim only page cache. ) Signed-off-by: Rik van Riel <riel@surriel.com> Signed-off-by: Ingo Molnar <mingo@kernel.org> Cc: Dave Hansen <dave.hansen@linux.intel.com> Cc: Andy Lutomirski <luto@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Linus Torvalds <torvalds@linux-foundation.org> Link: https://lore.kernel.org/r/20250319132520.6b10ad90@fangorn

2025-03-19perf/x86/intel, x86/cpu: Simplify Intel PMU initializationSohil Mehta
Architectural Perfmon was introduced on the Family 6 "Core" processors starting with Yonah. Processors before Yonah need their own customized PMU initialization. p6_pmu_init() is expected to provide that initialization for early Family 6 processors. But, currently, it could get called for any Family 6 processor if the architectural perfmon feature is disabled on that processor. To simplify, restrict the P6 PMU initialization to early Family 6 processors that do not have architectural perfmon support and truly need the special handling. As a result, the "unsupported" console print becomes practically unreachable because all the released P6 processors are covered by the switch cases. Move the console print to a common location where it can cover all modern processors (including Family >15) that may not have architectural perfmon support enumerated. Also, use this opportunity to get rid of the unnecessary switch cases in P6 initialization. Only the Pentium Pro processor needs a quirk, and the rest of the processors do not need any special handling. The gaps in the case numbers are only due to no processor with those model numbers being released. Use decimal numbers to represent Intel Family numbers. Also, convert one of the last few Intel x86_model comparisons to a VFM-based one.

2025-03-19x86/crc: drop the avx10_256 functions and rename avx10_512 to avx512Eric Biggers
Intel made a late change to the AVX10 specification that removes support for a 256-bit maximum vector length and enumeration of the maximum vector length. AVX10 will imply a maximum vector length of 512 bits. I.e. there won't be any such thing as AVX10/256 or AVX10/512; there will just be AVX10, and it will essentially just consolidate AVX512 features. As a result of this new development, my strategy of providing both *_avx10_256 and *_avx10_512 functions didn't turn out to be that useful. The only remaining motivation for the 256-bit AVX512 / AVX10 functions is to avoid downclocking on older Intel CPUs. But I already wrote *_avx2 code too (primarily to support CPUs without AVX512), which performs almost as well as *_avx10_256. So we should just use that. Therefore, remove the *_avx10_256 CRC functions, and rename the *_avx10_512 CRC functions to *_avx512. Make Ice Lake and Tiger Lake use the *_avx2 functions instead of *_avx10_256 which they previously used.

2025-03-19netconsole: allow selection of egress interface via MAC addressUday Shankar
Currently, netconsole has two methods of configuration - module parameter and configfs. The former interface allows for netconsole activation earlier during boot (by specifying the module parameter on the kernel command line), so it is preferred for debugging issues which arise before userspace is up/the configfs interface can be used. The module parameter syntax requires specifying the egress interface name. This requirement makes it hard to use for a couple reasons: - The egress interface name can be hard or impossible to predict. For example, installing a new network card in a system can change the interface names assigned by the kernel. - When constructing the module parameter, one may have trouble determining the original (kernel-assigned) name of the interface (which is the name that should be given to netconsole) if some stable interface naming scheme is in effect. A human can usually look at kernel logs to determine the original name, but this is very painful if automation is constructing the parameter. For these reasons, allow selection of the egress interface via MAC address when configuring netconsole using the module parameter. Update the netconsole documentation with an example of the new syntax. Selection of egress interface by MAC address via configfs is far less interesting (since when this interface can be used, one should be able to easily convert between MAC address and interface name), so it is left unimplemented.

2025-03-19gpu: host1x: Do not assume that a NULL domain means no DMA IOMMUJason Gunthorpe
Previously with tegra-smmu, even with CONFIG_IOMMU_DMA, the default domain could have been left as NULL. The NULL domain is specially recognized by host1x_iommu_attach() as meaning it is not the DMA domain and should be replaced with the special shared domain. This happened prior to the below commit because tegra-smmu was using the NULL domain to mean IDENTITY. Now that the domain is properly labled the test in DRM doesn't see NULL. Check for IDENTITY as well to enable the special domains. This is the same issue and basic fix as seen in commit fae6e669cdc5 ("drm/tegra: Do not assume that a NULL domain means no DMA IOMMU").
