2025-01-24archlinux_defconfig: Update defconfigv6.13Blaster43851-23/+3
2025-01-23IllusionX: Add graysky's more-uarchesgraysky3-17/+499
From https://github.com/graysky2/kernel_compiler_patch more-ISA-levels-and-uarches-for-kernel-6.1.79+.patch FEATURES This patch adds additional tunings via new x86-64 ISA levels and more micro-architecture options to the Linux kernel in three classes. 1. New generic x86-64 ISA levels These are selectable under: Processor type and features ---> x86-64 compiler ISA level • x86-64 A value of (1) is the default • x86-64-v2 A value of (2) brings support for vector instructions up to Streaming SIMD Extensions 4.2 (SSE4.2) and Supplemental Streaming SIMD Extensions 3 (SSSE3), the POPCNT instruction, and CMPXCHG16B. • x86-64-v3 A value of (3) adds vector instructions up to AVX2, MOVBE, and additional bit-manipulation instructions. There is also x86-64-v4 but including this makes little sense as the kernel does not use any of the AVX512 instructions anyway. Users of glibc 2.33 and above can see which level is supported by running: /lib/ld-linux-x86-64.so.2 --help | grep supported Or /lib64/ld-linux-x86-64.so.2 --help | grep supported 2. New micro-architectures These are selectable under: Processor type and features ---> Processor family • AMD Improved K8-family • AMD K10-family • AMD Family 10h (Barcelona) • AMD Family 14h (Bobcat) • AMD Family 16h (Jaguar) • AMD Family 15h (Bulldozer) • AMD Family 15h (Piledriver) • AMD Family 15h (Steamroller) • AMD Family 15h (Excavator) • AMD Family 17h (Zen) • AMD Family 17h (Zen 2) • AMD Family 19h (Zen 3)** • AMD Family 19h (Zen 4)‡ • AMD Family 1Ah (Zen 5)§ • Intel Silvermont low-power processors • Intel Goldmont low-power processors (Apollo Lake and Denverton) • Intel Goldmont Plus low-power processors (Gemini Lake) • Intel 1st Gen Core i3/i5/i7 (Nehalem) • Intel 1.5 Gen Core i3/i5/i7 (Westmere) • Intel 2nd Gen Core i3/i5/i7 (Sandybridge) • Intel 3rd Gen Core i3/i5/i7 (Ivybridge) • Intel 4th Gen Core i3/i5/i7 (Haswell) • Intel 5th Gen Core i3/i5/i7 (Broadwell) • Intel 6th Gen Core i3/i5/i7 (Skylake) • Intel 6th Gen Core i7/i9 (Skylake X) • Intel 8th Gen Core i3/i5/i7 (Cannon Lake) • Intel 10th Gen Core i7/i9 (Ice Lake) • Intel Xeon (Cascade Lake) • Intel Xeon (Cooper Lake)* • Intel 3rd Gen 10nm++ i3/i5/i7/i9-family (Tiger Lake)* • Intel 4th Gen 10nm++ Xeon (Sapphire Rapids)† • Intel 11th Gen i3/i5/i7/i9-family (Rocket Lake)† • Intel 12th Gen i3/i5/i7/i9-family (Alder Lake)† • Intel 13th Gen i3/i5/i7/i9-family (Raptor Lake)‡ • Intel 14th Gen i3/i5/i7/i9-family (Meteor Lake)‡ • Intel 5th Gen 10nm++ Xeon (Emerald Rapids)‡ Notes: If not otherwise noted, gcc >=9.1 is required for support. *Requires gcc >=10.1 or clang >=10.0 **Required gcc >=10.3 or clang >=12.0 †Required gcc >=11.1 or clang >=12.0 ‡Required gcc >=13.0 or clang >=15.0.5 §Required gcc >14.0 or clang >=19.0? 3. Auto-detected micro-architecture levels Compile by passing the '-march=native' option which, "selects the CPU to generate code for at compilation time by determining the processor type of the compiling machine. Using -march=native enables all instruction subsets supported by the local machine and will produce code optimized for the local machine under the constraints of the selected instruction set."[1] Users of Intel CPUs should select the 'Intel-Native' option and users of AMD CPUs should select the 'AMD-Native' option. MINOR NOTES RELATING TO INTEL ATOM PROCESSORS This patch also changes -march=atom to -march=bonnell in accordance with the gcc v4.9 changes. Upstream is using the deprecated -match=atom flags when I believe it should use the newer -march=bonnell flag for atom processors.[2] It is not recommended to compile on Atom-CPUs with the 'native' option.[3] The recommendation is to use the 'atom' option instead. BENEFITS Small but real speed increases are measurable using a make endpoint comparing a generic kernel to one built with one of the respective microarchs.

2025-01-23drivers/firmware: skip simpledrm if nvidia-drm.modeset=1 is setJavier Martinez Canillas1-1/+17
The Nvidia proprietary driver has some bugs that leads to issues if used with the simpledrm driver. The most noticeable is that does not register an emulated fbdev device. It just relies on a fbdev to be registered by another driver, that could be that could be attached to the framebuffer console. On UEFI machines, this is the efifb driver. This means that disabling the efifb driver will cause virtual consoles to not be present in the system when using the Nvidia driver. Legacy BIOS is not affected just because fbcon is not used there, but instead vgacon. Unless a VGA mode is specified using the vga= kernel command line option, in that case the vesafb driver is used instead and its fbdev attached to the fbcon. This is a problem because with CONFIG_SYSFB_SIMPLEFB=y, the sysfb platform code attempts to register a "simple-framebuffer" platform device (that is matched against simpledrm) and only registers either an "efi-framebuffer" or "vesa-framebuffer" if this fails to be registered due the video modes not being compatible. The Nvidia driver relying on another driver to register the fbdev is quite fragile, since it can't really assume those will stick around. For example there are patches posted to remove the EFI and VESA platform devices once a real DRM or fbdev driver probes. But in any case, moving to a simpledrm + emulated fbdev only breaks this assumption and causes users to not have VT if the Nvidia driver is used. So to prevent this, let's add a workaround and make the sysfb to skip the "simple-framebuffer" registration when nvidia-drm.modeset=1 option is set. This is quite horrible, but honestly I can't think of any other approach. For this to work, the CONFIG_FB_EFI and CONFIG_FB_VESA config options must be enabled besides CONFIG_DRM_SIMPLEDRM.

As defines get translated into their values in the trace event format files, the user space tooling could easily convert the GFP flags into their symbols via the __print_flags() helper macro. The problem is that enums do not get converted, and the names of the enums show up in the format files and user space tooling cannot translate them. Add TRACE_DEFINE_ENUM() around the enums used for GFP flags which is the tracing infrastructure macro that informs the tracing subsystem what the values for enums and it can then expose that to user space" * tag 'trace-v6.13-rc7-2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: tracing: gfp: Fix the GFP enum values shown for user space tracing tools

2025-01-17tracing: gfp: Fix the GFP enum values shown for user space tracing toolsSteven Rostedt1-0/+63
Tracing tools like perf and trace-cmd read the /sys/kernel/tracing/events/*/*/format files to know how to parse the data and also how to print it. For the "print fmt" portion of that file, if anything uses an enum that is not exported to the tracing system, user space will not be able to parse it. The GFP flags use to be defines, and defines get translated in the print fmt sections. But now they are converted to use enums, which is not. The mm_page_alloc trace event format use to have: print fmt: "page=%p pfn=0x%lx order=%d migratetype=%d gfp_flags=%s", REC->pfn != -1UL ? (((struct page *)vmemmap_base) + (REC->pfn)) : ((void *)0), REC->pfn != -1UL ? REC->pfn : 0, REC->order, REC->migratetype, (REC->gfp_flags) ? __print_flags(REC->gfp_flags, "|", {( unsigned long)(((((((( gfp_t)(0x400u|0x800u)) | (( gfp_t)0x40u) | (( gfp_t)0x80u) | (( gfp_t)0x100000u)) | (( gfp_t)0x02u)) | (( gfp_t)0x08u) | (( gfp_t)0)) | (( gfp_t)0x40000u) | (( gfp_t)0x80000u) | (( gfp_t)0x2000u)) & ~(( gfp_t)(0x400u|0x800u))) | (( gfp_t)0x400u)), "GFP_TRANSHUGE"}, {( unsigned long)((((((( gfp_t)(0x400u|0x800u)) | (( gfp_t)0x40u) | (( gfp_t)0x80u) | (( gfp_t)0x100000u)) | (( gfp_t)0x02u)) | (( gfp_t)0x08u) | (( gfp_t)0)) ... Where the GFP values are shown and not their names. But after the GFP flags were converted to use enums, it has: print fmt: "page=%p pfn=0x%lx order=%d migratetype=%d gfp_flags=%s", REC->pfn != -1UL ? (vmemmap + (REC->pfn)) : ((void *)0), REC->pfn != -1UL ? REC->pfn : 0, REC->order, REC->migratetype, (REC->gfp_flags) ? __print_flags(REC->gfp_flags, "|", {( unsigned long)(((((((( gfp_t)(((((1UL))) << (___GFP_DIRECT_RECLAIM_BIT))|((((1UL))) << (___GFP_KSWAPD_RECLAIM_BIT)))) | (( gfp_t)((((1UL))) << (___GFP_IO_BIT))) | (( gfp_t)((((1UL))) << (___GFP_FS_BIT))) | (( gfp_t)((((1UL))) << (___GFP_HARDWALL_BIT)))) | (( gfp_t)((((1UL))) << (___GFP_HIGHMEM_BIT)))) | (( gfp_t)((((1UL))) << (___GFP_MOVABLE_BIT))) | (( gfp_t)0)) | (( gfp_t)((((1UL))) << (___GFP_COMP_BIT))) ... Where the enums names like ___GFP_KSWAPD_RECLAIM_BIT are shown and not their values. User space has no way to convert these names to their values and the output will fail to parse. What is shown is now: mm_page_alloc: page=0xffffffff981685f3 pfn=0x1d1ac1 order=0 migratetype=1 gfp_flags=0x140cca The TRACE_DEFINE_ENUM() macro was created to handle enums in the print fmt files. This causes them to be replaced at boot up with the numbers, so that user space tooling can parse it. By using this macro, the output is back to the human readable: mm_page_alloc: page=0xffffffff981685f3 pfn=0x122233 order=0 migratetype=1 gfp_flags=GFP_HIGHUSER_MOVABLE|__GFP_COMP Cc: [email protected] Cc: Masami Hiramatsu <[email protected]> Cc: Mark Rutland <[email protected]> Cc: Mathieu Desnoyers <[email protected]> Cc: Andrew Morton <[email protected]> Cc: Veronika Molnarova <[email protected]> Cc: Suren Baghdasaryan <[email protected]> Cc: Linus Torvalds <[email protected]> Link: https://lore.kernel.org/[email protected] Reported-by: Michael Petlan <[email protected]> Closes: https://lore.kernel.org/all/[email protected]/ Fixes: 772dd0342727c ("mm: enumerate all gfp flags") Signed-off-by: Steven Rostedt (Google) <[email protected]>

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Fix a regression in the irqsoff and wakeup latency tracing The function graph tracer infrastructure has become generic so that fprobes and BPF can be based on it. As it use to only handle function graph tracing, it would always calculate the time the function entered so that it could then calculate the time it exits and give the length of time the function executed for. But this is not needed for the other users (fprobes and BPF) and reading the clock adds a non-negligible overhead, so the calculation was moved into the function graph tracer logic. But the irqsoff and wakeup latency tracers, when the "display-graph" option was set, would use the function graph tracer to calculate the times of functions during the latency. The movement of the calltime calculation made the value zero for these tracers, and the output no longer showed the length of time of each tracer, but instead the absolute timestamp of when the function returned (rettime - calltime where calltime is now zero). Have the irqsoff and wakeup latency tracers also do the calltime calculation as the function graph tracer does and report the proper length of the function timings. - Update the tracing display to reflect the new preempt lazy model When the system is configured with preempt lazy, the output of the trace data would state "unknown" for the current preemption model. Because the lazy preemption model was just added, make it known to the tracing subsystem too. This is just a one line change. - Document multiple function graph having slightly different timings Now that function graph tracer infrastructure is separate, this also allows the function graph tracer to run in multiple instances (it wasn't able to do so before). If two instances ran the function graph tracer and traced the same functions, the timings for them will be slightly different because each does their own timings and collects the timestamps differently. Document this to not have people be confused by it. * tag 'trace-v6.13-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: ftrace: Document that multiple function_graph tracing may have different times tracing: Print lazy preemption model tracing: Fix irqsoff and wakeup latency tracers when using function graph
