2022-12-13drm/i915: Bpp/timeslot calculation fixes for DP MST DSCStanislav Lisovskiy
Fix intel_dp_dsc_compute_config, previously timeslots parameter was used in fact not as a timeslots, but more like a ratio timeslots/64, which of course didn't have any effect for SST DSC, but causes now issues for MST DSC. Secondly we need to calculate pipe_bpp using intel_dp_dsc_compute_bpp only for SST DSC case, while for MST case it has been calculated earlier already with intel_dp_dsc_mst_compute_link_config. Third we also were wrongly determining sink min bpp/max bpp, those limites should be intersected with our limits to find common acceptable bpp's, plus on top of that we should align those with VESA bpps and only then calculate required timeslots amount. Some MST hubs started to work only after third change was made. v2: Make kernel test robot happy(claimed there was unitialzed use, while there is none) v3: Rename intel_dp_dsc_nearest_vesa_bpp to intel_dp_dsc_nearest_valid_bpp (Manasi Navare) Reviewed-by: Manasi Navare <manasi.d.navare@intel.com> Signed-off-by: Stanislav Lisovskiy <stanislav.lisovskiy@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20221123100718.29130-1-stanislav.lisovskiy@intel.com

We might to use that function separately from intel_dp_dsc_compute_config for DP DSC over MST case, because allocating bandwidth in that case can be a bit more tricky. So in order to avoid code copy-pasta lets extract this to separate function and reuse it for both SST and MST cases. v2: Removed multiple blank lines v3: Rename intel_dp_dsc_nearest_vesa_bpp to intel_dp_dsc_nearest_valid_bpp to reflect its meaning more properly.

2022-12-13drm/i915: Add DSC support to MST pathStanislav Lisovskiy
Whenever we are not able to get enough timeslots for required PBN, let's try to allocate those using DSC, just same way as we do for SST. v2: Removed intel_dp_mst_dsc_compute_config and refactored intel_dp_dsc_compute_config to support timeslots as a parameter(Ville Syrjälä) v3: - Rebased - Added a debug to see that we at least try reserving VCPI slots using DSC, because currently its not visible from the logs, thus making debugging more tricky. - Moved timeslots to numerator, where it should be. v4: - Call drm_dp_mst_atomic_check already during link config computation, because we need to know already by this moment if uncompressed amount of VCPI slots needed can fit, otherwise we need to use DSC. (thanks to Vinod Govindapillai for pointing this out) v5: - Put pipe_config->bigjoiner_pipes back to original condition in intel_dp_dsc_compute_config (don't remember when I lost it) v6: - Removed unnecessary drm_dp_mst_atomic_check as it is now always called in a newly introduced intel_dp_mst_find_vcpi_slots_for_bpp function (Vinod Govindapillai) Reviewed-by: Vinod Govindapillai <vinod.govindapillai@intel.com> Signed-off-by: Stanislav Lisovskiy <stanislav.lisovskiy@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20221101094222.22091-5-stanislav.lisovskiy@intel.com

2022-12-13drm/i915: Fix intel_dp_mst_compute_link_configStanislav Lisovskiy
We currently always exit that bpp loop because drm_dp_atomic_find_vcpi_slots doesn't care if we actually can fit those or not. I think that wasn't the initial intention here, especially when we keep trying with lower bpps, we are supposed to keep trying until we actually find some _working_ configuration, which isn't the case here. So added that drm_dp_mst_check here, so that we can make sure that try all the bpps before we fail.

2022-12-13kbuild: use .NOTINTERMEDIATE for future GNU Make versionsMasahiro Yamada
In Kbuild, some files are generated by chains of pattern/implicit rules. For example, *.dtb.o files in drivers/of/unittest-data/Makefile are generated by the chain of 3 pattern rules, like this: %.dts -> %.dtb -> %.dtb.S -> %.dtb.o Here, %.dts is the real source, %.dtb.o is the final target. %.dtb and %.dtb.S are called "intermediate files". As GNU Make manual [1] says, intermediate files are treated differently in two ways: (a) The first difference is what happens if the intermediate file does not exist. If an ordinary file 'b' does not exist, and make considers a target that depends on 'b', it invariably creates 'b' and then updates the target from 'b'. But if 'b' is an intermediate file, then make can leave well enough alone: it won't create 'b' unless one of its prerequisites is out of date. This means the target depending on 'b' won't be rebuilt either, unless there is some other reason to update that target: for example the target doesn't exist or a different prerequisite is newer than the target. (b) The second difference is that if make does create 'b' in order to update something else, it deletes 'b' later on after it is no longer needed. Therefore, an intermediate file which did not exist before make also does not exist after make. make reports the deletion to you by printing a 'rm' command showing which file it is deleting. The combination of these is problematic for Kbuild because most of the build rules depend on FORCE and the if_changed* macros really determine if the target should be updated. So, all missing files, whether they are intermediate or not, are always rebuilt. To see the problem, delete ".SECONDARY:" from scripts/Kbuild.include, and repeat this command: $ make allmodconfig drivers/of/unittest-data/ The intermediate files will be deleted, which results in rebuilding intermediate and final objects in the next run of make. In the old days, people suppressed (b) in inconsistent ways. As commit 54a702f70589 ("kbuild: mark $(targets) as .SECONDARY and remove .PRECIOUS markers") noted, you should not use .PRECIOUS because .PRECIOUS has the following behavior (c), which is not likely what you want. (c) If make is killed or interrupted during the execution of their recipes, the target is not deleted. Also, the target is not deleted on error even if .DELETE_ON_ERROR is specified. .SECONDARY is a much better way to disable (b), but a small problem is that .SECONDARY enables (a), which gives a side-effect to $?; prerequisites marked as .SECONDARY do not appear in $?. This is a drawback for Kbuild. I thought it was a bug and opened a bug report. As Paul, the GNU Make maintainer, concluded in [2], this is not a bug. A good news is that, GNU Make 4.4 added the perfect solution, .NOTINTERMEDIATE, which cancels both (a) and (b). For clarificaton, my understanding of .INTERMEDIATE, .SECONDARY, .PRECIOUS and .NOTINTERMEDIATE are as follows: (a) (b) (c) .INTERMEDIATE enable enable disable .SECONDARY enable disable disable .PRECIOUS disable disable enable .NOTINTERMEDIATE disable disable disable However, GNU Make 4.4 has a bug for the global .NOTINTERMEDIATE. [3] It was fixed by commit 6164608900ad ("[SV 63417] Ensure global .NOTINTERMEDIATE disables all intermediates"), and will be available in the next release of GNU Make. The following is the gain for .NOTINTERMEDIATE: [Current Make] $ make allnoconfig vmlinux [ full build ] $ rm include/linux/device.h $ make vmlinux CALL scripts/checksyscalls.sh Make does not notice the removal of <linux/device.h>.

GNU Make 4.4 introduced $(intcmp ...), which is useful to compare two integers without forking a new process. Add test-{ge,gt,le,lt} macros, which work more efficiently with GNU Make >= 4.4. For older Make versions, they fall back to the 'test' shell command. The first two parameters to $(intcmp ...) must not be empty. To avoid the syntax error, I appended '0' to them. Fortunately, '00' is treated as '0'. This is needed because CONFIG options may expand to an empty string when the kernel configuration is not included.

2022-12-12riscv: Fix P4D_SHIFT definition for 3-level page table modeAlexandre Ghiti
RISC-V kernels support 3,4,5-level page tables at runtime by folding upper levels. In case of a 3-level page table, PGDIR is folded into P4D which in turn is folded into PUD: PGDIR_SHIFT value is correctly set to the same value as PUD_SHIFT, but P4D_SHIFT is not, then any use of P4D_SHIFT will access invalid address bits (all set to 1). Fix this by dynamically defining P4D_SHIFT value, like we already do for PGDIR_SHIFT.

2022-12-12riscv: Apply a static assert to riscv_isa_ext_idAndrew Jones
Add a static assert to ensure a RISCV_ISA_EXT_* enum is never created with a value >= RISCV_ISA_EXT_MAX. We can do this by putting RISCV_ISA_EXT_ID_MAX to more work. Before it was redundant with RISCV_ISA_EXT_MAX and hence only used to document the limit. Now it grows with the enum and is used to check the limit.

Pull nfsd updates from Chuck Lever: "This release introduces support for the CB_RECALL_ANY operation. NFSD can send this operation to request that clients return any delegations they choose. The server uses this operation to handle low memory scenarios or indicate to a client when that client has reached the maximum number of delegations the server supports. The NFSv4.2 READ_PLUS operation has been simplified temporarily whilst support for sparse files in local filesystems and the VFS is improved. Two major data structure fixes appear in this release: - The nfs4_file hash table is replaced with a resizable hash table to reduce the latency of NFSv4 OPEN operations. - Reference counting in the NFSD filecache has been hardened against races. In furtherance of removing support for NFSv2 in a subsequent kernel release, a new Kconfig option enables server-side support for NFSv2 to be left out of a kernel build.

User visible features: - raid56 reliability vs performance trade off: - fix destructive RMW for raid5 data (raid6 still needs work): do full checksum verification for all data during RMW cycle, this should prevent rewriting potentially corrupted data without notice - stripes are cached in memory which should reduce the performance impact but still can hurt some workloads - checksums are verified after repair again - this is the last option without introducing additional features (write intent bitmap, journal, another tree), the extra checksum read/verification was supposed to be avoided by the original implementation exactly for performance reasons but that caused all the reliability problems - discard=async by default for devices that support it - implement emergency flush reserve to avoid almost all unnecessary transaction aborts due to ENOSPC in cases where there are too many delayed refs or delayed allocation - skip block group synchronization if there's no change in used bytes, can reduce transaction commit count for some workloads Performance improvements: - fiemap and lseek: - overall speedup due to skipping unnecessary or duplicate searches (-40% run time) - cache some data structures and sharedness of extents (-30% run time) - send: - faster backref resolution when finding clones - cached leaf to root mapping for faster backref walking - improved clone/sharing detection - overall run time improvements (-70%) Core: - module initialization converted to a table of function pointers run in a sequence - preparation for fscrypt, extend passing file names across calls, dir item can store encryption status - raid56 updates: - more accurate error tracking of sectors within stripe - simplify recovery path and remove dedicated endio worker kthread - simplify scrub call paths - refactoring to support the extra data checksum verification during RMW cycle - tree block parentness checks consolidated and done at metadata read time - improved error handling - cleanups: - move a lot of code for better synchronization between kernel and user space sources, split big files - enum cleanups - GFP flag cleanups - header file cleanups, prototypes, dependencies - redundant parameter cleanups - inline extent handling simplifications - inode parameter conversion - data structure cleanups, reductions, renames, merges" * tag 'for-6.2-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: (249 commits) btrfs: print transaction aborted messages with an error level btrfs: sync some cleanups from progs into uapi/btrfs.h btrfs: do not BUG_ON() on ENOMEM when dropping extent items for a range btrfs: fix extent map use-after-free when handling missing device in read_one_chunk btrfs: remove outdated logic from overwrite_item() and add assertion btrfs: unify overwrite_item() and do_overwrite_item() btrfs: replace strncpy() with strscpy() btrfs: fix uninitialized variable in find_first_clear_extent_bit btrfs: fix uninitialized parent in insert_state btrfs: add might_sleep() annotations btrfs: add stack helpers for a few btrfs items btrfs: add nr_global_roots to the super block definition btrfs: remove BTRFS_LEAF_DATA_OFFSET btrfs: add helpers for manipulating leaf items and data btrfs: add eb to btrfs_node_key_ptr_offset btrfs: pass the extent buffer for the btrfs_item_nr helpers btrfs: move the csum helpers into ctree.h btrfs: move eb offset helpers into extent_io.h btrfs: move file_extent_item helpers into file-item.h btrfs: move leaf_data_end into ctree.c ...
