Hopefully for 6.3 we will be able to line up a driver to use it. In drivers land, i915 enables DG2 support by default now, and nouveau has a big stability refactoring and initial ampere support, AMD includes new hw IP support and should build on ARM again. There is also an ofdrm driver to take over offb on platforms it's used. Stuff outside my tree, the dma-buf patches hit a few places, the vc4 firmware changes also do, and i915 has some interactions with MEI for discrete GPUs. I think all of those should have been acked/reviewed by relevant parties.

target destruction in DM targets: thin-pool, cache, integrity and clone. - Fix ABBA deadlocks in DM thin-pool and cache targets due to their use of a bufio client (that has a shrinker whose locking can cause the incorrect locking order). - Fix DM cache target to set its needs_check flag after first aborting the metadata (whereby using reset persistent-data objects to update the superblock with, otherwise the superblock update could be dropped due to aborting metadata). This was found with code-inspection when comparing with the equivalent in DM thinp code. - Fix DM thin-pool's presume to continue resuming the device even if the pool in is fail mode -- otherwise bios may never be failed up the IO stack (which will prevent resetting the thin-pool target via table reload) - Fix DM thin-pool's metadata to use proper btree root (from previous transaction) if metadata commit failed. - Add 'waitfor' module param to DM module (dm_mod) to allow dm-init to wait for the specified device before continuing with its DM target initialization. -----BEGIN PGP SIGNATURE----- iQEzBAABCAAdFiEEJfWUX4UqZ4x1O2wixSPxCi2dA1oFAmOXp8IACgkQxSPxCi2d A1rS2wf/VF82dcQpsAAT05L6j6xqo/eUe3Q3AZYbJGRl1Kg41NE/YRA1A/lsxykO j3wZut5UyL0ZEsjHhhUMC8rOeexfyqiecVdMofuQRkKJYa4l85IbPBE2qOMi/Ida WMsZg8bmm01hDPpZRUwj7L5BRDJlB0n9hdtkh16K0gboiaPZxmIEtum0IYr8krPj hOv6amx9MhrsiUcVWylFipmxTgpsxwwg67g2R6tCGUmHQhxHKFInvySrYdv5hYdy 3kr1pxy87Wn3oETrHNNc506qh6QK85mOC+D/VdNNzNnM6yhgOEkE9lSS/Er2rHyT D6Af4j5SIBy/srv5DjcWd7pi4NHIBA== =fuDb -----END PGP SIGNATURE----- Merge tag 'for-6.2/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper updates from Mike Snitzer: - Fix use-after-free races due to missing resource cleanup during DM target destruction in DM targets: thin-pool, cache, integrity and clone. - Fix ABBA deadlocks in DM thin-pool and cache targets due to their use of a bufio client (that has a shrinker whose locking can cause the incorrect locking order). - Fix DM cache target to set its needs_check flag after first aborting the metadata (whereby using reset persistent-data objects to update the superblock with, otherwise the superblock update could be dropped due to aborting metadata).

This was a not-too-busy cycle for documentation; highlights include:
- The beginnings of a set of translations into Spanish, headed up by Carlos
Bilbao.
- More Chinese translations.
- A change to the Sphinx "alabaster" theme by default for HTML generation.
Unlike the previous default (Read the Docs), alabaster is shipped with
Sphinx by default, reducing the number of other dependencies that need to
be installed. It also (IMO) produces a cleaner and more readable result.
- The ability to render the documentation into the texinfo format
(something Sphinx could always do, we just never wired it up until now).
Plus the usual collection of typo fixes, build-warning fixes, and minor
updates.

Pull random number generator updates from Jason Donenfeld:
- Replace prandom_u32_max() and various open-coded variants of it,
there is now a new family of functions that uses fast rejection
sampling to choose properly uniformly random numbers within an
interval:
get_random_u32_below(ceil) - [0, ceil)
get_random_u32_above(floor) - (floor, U32_MAX]
get_random_u32_inclusive(floor, ceil) - [floor, ceil]
Coccinelle was used to convert all current users of
prandom_u32_max(), as well as many open-coded patterns, resulting in
improvements throughout the tree.
I'll have a "late" 6.1-rc1 pull for you that removes the now unused
prandom_u32_max() function, just in case any other trees add a new
use case of it that needs to converted. According to linux-next,
there may be two trivial cases of prandom_u32_max() reintroductions
that are fixable with a 's/.../.../'. So I'll have for you a final
conversion patch doing that alongside the removal patch during the
second week.
This is a treewide change that touches many files throughout.
- More consistent use of get_random_canary().
- Updates to comments, documentation, tests, headers, and
simplification in configuration.
- The arch_get_random*_early() abstraction was only used by arm64 and
wasn't entirely useful, so this has been replaced by code that works
in all relevant contexts.
- The kernel will use and manage random seeds in non-volatile EFI
variables, refreshing a variable with a fresh seed when the RNG is
initialized. The RNG GUID namespace is then hidden from efivarfs to
prevent accidental leakage.
These changes are split into random.c infrastructure code used in the
EFI subsystem, in this pull request, and related support inside of
EFISTUB, in Ard's EFI tree. These are co-dependent for full
functionality, but the order of merging doesn't matter.
- Part of the infrastructure added for the EFI support is also used for
an improvement to the way vsprintf initializes its siphash key,
replacing an sleep loop wart.
- The hardware RNG framework now always calls its correct random.c
input function, add_hwgenerator_randomness(), rather than sometimes
going through helpers better suited for other cases.
- The add_latent_entropy() function has long been called from the fork
handler, but is a no-op when the latent entropy gcc plugin isn't
used, which is fine for the purposes of latent entropy.
But it was missing out on the cycle counter that was also being mixed
in beside the latent entropy variable. So now, if the latent entropy
gcc plugin isn't enabled, add_latent_entropy() will expand to a call
to add_device_randomness(NULL, 0), which adds a cycle counter,
without the absent latent entropy variable.
- The RNG is now reseeded from a delayed worker, rather than on demand
when used. Always running from a worker allows it to make use of the
CPU RNG on platforms like S390x, whose instructions are too slow to
do so from interrupts. It also has the effect of adding in new inputs
more frequently with more regularity, amounting to a long term
transcript of random values. Plus, it helps a bit with the upcoming
vDSO implementation (which isn't yet ready for 6.2).
- The jitter entropy algorithm now tries to execute on many different
CPUs, round-robining, in hopes of hitting even more memory latencies
and other unpredictable effects. It also will mix in a cycle counter
when the entropy timer fires, in addition to being mixed in from the
main loop, to account more explicitly for fluctuations in that timer
firing. And the state it touches is now kept within the same cache
line, so that it's assured that the different execution contexts will
cause latencies.

s390 updates for 6.2 merge window
- Factor out handle_write() function and simplify 3215 console
write operation.
- When 3170 terminal emulator is connected to the 3215 console
driver the boot time could be very long due to limited buffer
space or missing operator input. Add con3215_drop command line
parameter and con3215_drop sysfs attribute file to instruct
the kernel drop console data when such conditions are met.
- Fix white space errors in 3215 console driver.
- Move enum paiext_mode definition to a header file and rename
it to paievt_mode to indicate this is now used for several
events. Rename PAI_MODE_COUNTER to PAI_MODE_COUNTING to make
consistent with PAI_MODE_SAMPLING.
- Simplify the logic of PMU pai_crypto mapped buffer reference
counter and make it consistent with PMU pai_ext.
- Rename PMU pai_crypto mapped buffer structure member users
to active_events to make it consistent with PMU pai_ext.
- Enable HUGETLB_PAGE_OPTIMIZE_VMEMMAP configuration option.
This results in saving of 12K per 1M hugetlb page (~1.2%)
and 32764K per 2G hugetlb page (~1.6%).
- Use generic serial.h, bugs.h, shmparam.h and vga.h header
files and scrap s390-specific versions.
- The generic percpu setup code does not expect the s390-like
implementation and emits a warning. To get rid of that warning
and provide sane CPU-to-node and CPU-to-CPU distance mappings
implementat a minimal version of setup_per_cpu_areas().
- Use kstrtobool() instead of strtobool() for re-IPL sysfs device
attributes.
- Avoid unnecessary lookup of a pointer to MSI descriptor when
setting IRQ affinity for a PCI device.
- Get rid of "an incompatible function type cast" warning by
changing debug_sprintf_format_fn() function prototype so it
matches the debug_format_proc_t function type.
- Remove unused info_blk_hdr__pcpus() and get_page_state()
functions.
- Get rid of clang "unused unused insn cache ops function"
warning by moving s390_insn definition to a private header.
- Get rid of clang "unused function" warning by making function
raw3270_state_final() only available if CONFIG_TN3270_CONSOLE
is enabled.
- Use kstrobool() to parse sclp_con_drop parameter to make it
identical to the con3215_drop parameter and allow passing
values like "yes" and "true".
- Use sysfs_emit() for all SCLP sysfs show functions, which is
the current standard way to generate output strings.
- Make SCLP con_drop sysfs attribute also writable and allow to
change its value during runtime. This makes SCLP console drop
handling consistent with the 3215 device driver.
- Virtual and physical addresses are indentical on s390. However,
there is still a confusion when pointers are directly casted to
physical addresses or vice versa. Use correct address converters
virt_to_phys() and phys_to_virt() for s390 channel IO drivers.
- Support for power managemant has been removed from s390 since
quite some time. Remove unused power managemant code from the
appldata device driver.
- Allow memory tools like KASAN see memory accesses from the
checksum code. Switch to GENERIC_CSUM if KASAN is enabled,
just like x86 does.
- Add support of ECKD DASDs disks so it could be used as boot
and dump devices.
- Follow checkpatch recommendations and use octal values instead
of S_IRUGO and S_IWUSR for dump device attributes in sysfs.
- Changes to vx-insn.h do not cause a recompile of C files that
use asm(".include \"asm/vx-insn.h\"\n") magic to access vector
instruction macros from inline assemblies. Add wrapper include
header file to avoid this problem.
- Use vector instruction macros instead of byte patterns to
increase register validation routine readability.
- The current machine check register validation handling does not
take into account various scenarios and might lead to killing a
wrong user process or potentially ignore corrupted FPU registers.
Simplify logic of the machine check handler and stop the whole
machine if the previous context was kerenel mode. If the previous
context was user mode, kill the current task.
- Introduce sclp_emergency_printk() function which can be used to
emit a message in emergency cases. It is supposed to be used in
cases where regular console device drivers may not work anymore,
e.g. unrecoverable machine checks.
Keep the early Service-Call Control Block so it can also be used
after initdata has been freed to allow sclp_emergency_printk()
implementation.
- In case a system will be stopped because of an unrecoverable
machine check error print the machine check interruption code
to give a hint of what went wrong.
- Move storage error checking from the assembly entry code to C
in order to simplify machine check handling. Enter the handler
with DAT turned on, which simplifies the entry code even more.
- The machine check extended save areas are allocated using
a private "nmi_save_areas" slab cache which guarantees a
required power-of-two alignment. Get rid of that cache in
favour of kmalloc().

- Seperate 'struct ftrace_regs' from 'struct pt_regs' in core ftrace
and existing arch code
- Introduce and implement FTRACE_WITH_ARGS on arm64 to replace the
old FTRACE_WITH_REGS
- Extend 'crashkernel=' parameter with default value and fallback to
placement above 4G physical if initial (low) allocation fails
SVE:
- Optimisation to avoid disabling SVE unconditionally on syscall
entry and just zeroing the non-shared state on return instead
Exceptions:
- Rework of undefined instruction handling to avoid serialisation on
global lock (this includes emulation of user accesses to the ID
registers)
Perf and PMU:
- Support for TLP filters in Hisilicon's PCIe PMU device
- Support for the DDR PMU present in Amlogic Meson G12 SoCs
- Support for the terribly-named "CoreSight PMU" architecture from
Arm (and Nvidia's implementation of said architecture)
Misc:
- Tighten up our boot protocol for systems with memory above 52 bits
physical
- Const-ify static keys to satisty jump label asm constraints
- Trivial FFA driver cleanups in preparation for v1.1 support
- Export the kernel_neon_* APIs as GPL symbols
- Harden our instruction generation routines against instrumentation
- A bunch of robustness improvements to our arch-specific selftests
- Minor cleanups and fixes all over (kbuild, kprobes, kfence, PMU, ...)"

dm init: add dm-mod.waitfor to wait for asynchronously probed block devices
Just calling wait_for_device_probe() is not enough to ensure that
asynchronously probed block devices are available (E.G. mmc, usb), so
add a "dm-mod.waitfor=<device1>[,..,<deviceN>]" parameter to get
dm-init to explicitly wait for specific block devices before
initializing the tables with logic similar to the rootwait logic that
was introduced with commit

media: visl: add virtual stateless decoder driver
A virtual stateless device for stateless uAPI development purposes. This tool's objective is to help the development and testing of userspace applications that use the V4L2 stateless API to decode media. A userspace implementation can use visl to run a decoding loop even when no hardware is available or when the kernel uAPI for the codec has not been upstreamed yet. This can reveal bugs at an early stage. This driver can also trace the contents of the V4L2 controls submitted to it. It can also dump the contents of the vb2 buffers through a debugfs interface. This is in many ways similar to the tracing infrastructure available for other popular encode/decode APIs out there and can help develop a userspace application by using another (working) one as a reference. Note that no actual decoding of video frames is performed by visl. The V4L2 test pattern generator is used to write various debug information to the capture buffers instead.

drivers/accel: define kconfig and register a new major
Add a new Kconfig for the accel subsystem. The Kconfig currently contains only the basic CONFIG_DRM_ACCEL option that will be used to decide whether to compile the accel registration code. Therefore, the kconfig option is defined as bool. The accel code will be compiled as part of drm.ko and will be called directly from the DRM core code. The reason we compile it as part of drm.ko and not as a separate module is because of cyclic dependency between drm.ko and the separate module (if it would have existed). This is due to the fact that DRM core code calls accel functions and vice-versa. The accelerator devices will be exposed to the user space with a new, dedicated major number - 261. The accel init function registers the new major number as a char device and create corresponding sysfs and debugfs root entries, similar to what is done in DRM init function. I added a new header called drm_accel.h to include/drm/, that will hold the prototypes of the drm_accel.c functions. In case CONFIG_DRM_ACCEL is set to 'N', that header will contain empty inline implementations of those functions, to allow DRM core code to compile successfully without dependency on CONFIG_DRM_ACCEL. I Updated the MAINTAINERS file accordingly with the newly added folder and I have taken the liberty to appropriate the dri-devel mailing list and the dri-devel IRC channel for the accel subsystem.

core_pattern: add CPU specifier
Statistically, in a large deployment regular segfaults may indicate a CPU issue. Currently, it is not possible to find out what CPU the segfault happened on. There are at least two attempts to improve segfault logging with this regard, but they do not help in case the logs rotate. Hence, lets make sure it is possible to permanently record a CPU the task ran on using a new core_pattern specifier.

It's very unusual to have both a command line option and a compile time option, and apparently that's confusing to people. Also, basically everybody enables the compile time option now, which means people who want to disable this wind up having to use the command line option to ensure that anyway. So just reduce the number of moving pieces and nix the compile time option in favor of the more versatile command line option. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com> |

drm: Move nomodeset kernel parameter to drivers/video
Move the nomodeset kernel parameter to drivers/video to make it available to non-DRM drivers. Adapt the interface, but keep the DRM interface drm_firmware_drivers_only() to avoid churn within DRM. The function should later be inlined into callers. The parameter disables any DRM graphics driver that would replace a driver for firmware-provided scanout buffers. It is an option to easily fallback to basic graphics output if the hardware's native driver is broken. Moving it to a more prominent location wil make it available to fbdev as well. v2: * clarify the meaning of the nomodeset parameter (Javier) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20221111133024.9897-2-tzimmermann@suse.de |

s390/con3215: Drop console data printout when buffer full
Using z/VM the 3270 terminal emulator also emulates an IBM 3215 console which outputs line by line. When the screen is full, the console enters the MORE... state and waits for the operator to confirm the data on the screen by pressing a clear key. If this does not happen in the default time frame (currently 50 seconds) the console enters the HOLDING state. It then waits another time frame (currently 10 seconds) before the output continues on the next screen. When the operator presses the clear key during these wait times, the output continues immediately. This may lead to a very long boot time when the console has to print many messages, also the system may hang because of the console's limited buffer space and the system waits for the console output to drain and finally to finish. This problem can only occur when a terminal emulator is actually connected to the 3215 console driver. If not z/VM simply drops console output. Remedy this rare situation and add a kernel boot command line parameter con3215_drop. It can be set to 0 (do not drop) or 1 (do drop) which is the default. This instructs the kernel drop console data when the console buffer is full. This speeds up the boot time considerable and also does not hang the system anymore. Add a sysfs attribute file for console IBM 3215 named con_drop. This allows for changing the behavior after the boot, for example when during interactive debugging a panic/crash is expected. Here is a test of the new behavior using the following test program: #/bin/bash declare -i cnt=4 mode=$(cat /sys/bus/ccw/drivers/3215/con_drop) [ $mode = yes ] && cnt=25 echo "cons_drop $(cat /sys/bus/ccw/drivers/3215/con_drop)" echo "vmcp term more 5 2" vmcp term more 5 2 echo "Run $cnt iterations of "'echo t > /proc/sysrq-trigger' for i in $(seq $cnt) do echo "$i. command 'echo t > /proc/sysrq-trigger' at $(date +%F,%T)" echo t > /proc/sysrq-trigger sleep 1 done echo "droptest done" > /dev/kmsg # Output with sysfs attribute con_drop set to 1: # ./droptest.sh cons_drop yes vmcp term more 5 2 Run 25 iterations of echo t > /proc/sysrq-trigger 1. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:09 2. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:10 3. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:11 4. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:12 5. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:13 6. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:14 7. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:15 8. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:16 9. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:17 10. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:18 11. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:19 12. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:20 13. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:21 14. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:22 15. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:23 16. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:24 17. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:25 18. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:26 19. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:27 20. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:28 21. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:29 22. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:30 23. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:31 24. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:32 25. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:33 # There are no hangs anymore.

Function raw3125_putchar() just forwards its character for output to raw3215_write(). This moves tab to blank conversion to one function raw3215_write() which also does call raw3215_make_room() to wait for enough free buffer space. Function handle_write() loops over all its input and segments input into chunks of console buffer size (should the input be larger). Rework tab expansion handling logic to avoid code duplication.
