git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 fixes from Thomas Gleixner: - Ensure that the encryption mask at boot is properly propagated on 5-level page tables, otherwise the PGD entry is incorrectly set to non-encrypted, which causes system crashes during boot. - Undo the deferred 5-level page table setup as it cannot work with memory encryption enabled. - Prevent inconsistent XFD state on CPU hotplug, where the MSR is reset to the default value but the cached variable is not, so subsequent comparisons might yield the wrong result and as a consequence the result prevents updating the MSR. - Register the local APIC address only once in the MPPARSE enumeration to prevent triggering the related WARN_ONs() in the APIC and topology code. - Handle the case where no APIC is found gracefully by registering a fake APIC in the topology code. That makes all related topology functions work correctly and does not affect the actual APIC driver code at all. - Don't evaluate logical IDs during early boot as the local APIC IDs are not yet enumerated and the invoked function returns an error code. Nothing requires the logical IDs before the final CPUID enumeration takes place, which happens after the enumeration. - Cure the fallout of the per CPU rework on UP which misplaced the copying of boot_cpu_data to per CPU data so that the final update to boot_cpu_data got lost which caused inconsistent state and boot crashes. - Use copy_from_kernel_nofault() in the kprobes setup as there is no guarantee that the address can be safely accessed. - Reorder struct members in struct saved_context to work around another kmemleak false positive - Remove the buggy code which tries to update the E820 kexec table for setup_data as that is never passed to the kexec kernel. - Update the resource control documentation to use the proper units. - Fix a Kconfig warning observed with tinyconfig * tag 'x86-urgent-2024-03-24' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/boot/64: Move 5-level paging global variable assignments back x86/boot/64: Apply encryption mask to 5-level pagetable update x86/cpu: Add model number for another Intel Arrow Lake mobile processor x86/fpu: Keep xfd_state in sync with MSR_IA32_XFD Documentation/x86: Document that resctrl bandwidth control units are MiB x86/mpparse: Register APIC address only once x86/topology: Handle the !APIC case gracefully x86/topology: Don't evaluate logical IDs during early boot x86/cpu: Ensure that CPU info updates are propagated on UP kprobes/x86: Use copy_from_kernel_nofault() to read from unsafe address x86/pm: Work around false positive kmemleak report in msr_build_context() x86/kexec: Do not update E820 kexec table for setup_data x86/config: Fix warning for 'make ARCH=x86_64 tinyconfig'

2024-03-24Documentation/x86: Document that resctrl bandwidth control units are MiBTony Luck
The memory bandwidth software controller uses 2^20 units rather than 10^6. See mbm_bw_count() which computes bandwidth using the "SZ_1M" Linux define for 0x00100000. Update the documentation to use MiB when describing this feature. It's too late to fix the mount option "mba_MBps" as that is now an established user interface.

git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux Pull remoteproc updates from Bjorn Andersson: "Qualcomm SM8650 audio, compute and modem remoteproc are added. Qualcomm X1 Elite audio and compute remoteprocs are added, after support for shutting down the bootloader-loaded firmware loaded into the audio DSP..

2024-03-20tools/rtla: Add -U/--user-load option to timerlatDaniel Bristot de Oliveira
The timerlat tracer provides an interface for any application to wait for the timerlat's periodic wakeup. Currently, rtla timerlat uses it to dispatch its user-space workload (-u option). But as the tracer interface is generic, rtla timerlat can also be used to monitor any workload that uses it. For example, a user might place their own workload to wait on the tracer interface, and monitor the results with rtla timerlat. Add the -U option to rtla timerlat top and hist. With this option, rtla timerlat will not dispatch its workload but only setting up the system, waiting for a user to dispatch its workload. The sample code in this patch is an example of python application that loops in the timerlat tracer fd. To use it, dispatch: # rtla timerlat -U In a terminal, then run the python program on another terminal, specifying the CPU to run it. For example, setting on CPU 1: #./timerlat_load.py 1 Then rtla timerlat will start printing the statistics of the ./timerlat_load.py app. An interesting point is that the "Ret user Timer Latency" value is the overall response time of the load. The sample load does a memory copy to exemplify that. The stop tracing options on rtla timerlat works in this setup as well, including auto analysis.

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing updates from Steven Rostedt: "Main user visible change: - User events can now have "multi formats" The current user events have a single format. If another event is created with a different format, it will fail to be created. That is, once an event name is used, it cannot be used again with a different format. This can cause issues if a library is using an event and updates its format. An application using the older format will prevent an application using the new library from registering its event. A task could also DOS another application if it knows the event names, and it creates events with different formats. The multi-format event is in a different name space from the single format. Both the event name and its format are the unique identifier. This will allow two different applications to use the same user event name but with different payloads. - Added support to have ftrace_dump_on_oops dump out instances and not just the main top level tracing buffer. Other changes: - Add eventfs_root_inode Only the root inode has a dentry that is static (never goes away) and stores it upon creation. There's no reason that the thousands of other eventfs inodes should have a pointer that never gets set in its descriptor. Create a eventfs_root_inode desciptor that has a eventfs_inode descriptor and a dentry pointer, and only the root inode will use this. - Added WARN_ON()s in eventfs There's some conditionals remaining in eventfs that should never be hit, but instead of removing them, add WARN_ON() around them to make sure that they are never hit. - Have saved_cmdlines allocation also include the map_cmdline_to_pid array The saved_cmdlines structure allocates a large amount of data to hold its mappings. Within it, it has three arrays. Two are already apart of it: map_pid_to_cmdline[] and saved_cmdlines[]. More memory can be saved by also including the map_cmdline_to_pid[] array as well. - Restructure __string() and __assign_str() macros used in TRACE_EVENT() Dynamic strings in TRACE_EVENT() are declared with: __string(name, source) And assigned with: __assign_str(name, source) In the tracepoint callback of the event, the __string() is used to get the size needed to allocate on the ring buffer and __assign_str() is used to copy the string into the ring buffer. There's a helper structure that is created in the TRACE_EVENT() macro logic that will hold the string length and its position in the ring buffer which is created by __string(). There are several trace events that have a function to create the string to save. This function is executed twice. Once for __string() and again for __assign_str(). There's no reason for this. The helper structure could also save the string it used in __string() and simply copy that into __assign_str() (it also already has its length). By using the structure to store the source string for the assignment, it means that the second argument to __assign_str() is no longer needed. It will be removed in the next merge window, but for now add a warning if the source string given to __string() is different than the source string given to __assign_str(), as the source to __assign_str() isn't even used and will be going away. - Added checks to make sure that the source of __string() is also the source of __assign_str() so that it can be safely removed in the next merge window.

Furthermore describe better what tasks the script ideally performs so that users can more easily check if those have been taken care of. In addition to that point to the distro's documentation for further details on installing kernels manually.

2024-03-18docs: *-regressions.rst: Add colon to regzbot commandsNícolas F. R. A. Prado
Use colon as command terminator everywhere for consistency, even though it's not strictly necessary. That way it will also match regzbot's reference documentation.

2024-03-16Merge tag 'cxl-for-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxlLinus Torvalds
Pull CXL updates from Dan Williams: "CXL has mechanisms to enumerate the performance characteristics of memory devices. Those mechanisms allow Linux to build the equivalent of ACPI SRAT, SLIT, and HMAT tables dynamically at runtime. That capability is necessary because static ACPI can not represent dynamic CXL configurations (and reconfigurations). So, building on the v6.8 work to add "Quality of Service" enumeration, this update plumbs CXL "access coordinates" (read/write access latency and bandwidth) in all the same places that ACPI HMAT feeds similar data. Follow-on patches from the -mm side can then use that data to feed mechanisms like mm/memory-tiers.c. Greg has acked the touch to drivers/base/. The other feature update this cycle is support for CXL error injection via the ACPI EINJ module. That facility enables injection of bus protocol errors provided the user knows the magic address values to insert in the interface. To hide that magic, and make this easier to use, new error injection attributes were added to CXL debugfs. That interface injects the errors relative to a CXL object rather than require user tooling to know how to lookup and inject RCRB (Root Complex Register Block) addresses into the raw EINJ debugfs interface. It received some helpful review comments from Tony, but no explicit acks from the ACPI side. The primary user visible change for existing EINJ users is that they may find that einj.ko was already loaded by cxl_core.ko. Previously, einj.ko was only loaded on demand. The usual collection of miscellaneous cleanups are also present this cycle.
