2021-03-31drm/displayid: add new displayid section/block iteratorsJani Nikula1-0/+18
Iterating DisplayID blocks across sections (in EDID extensions) is unnecessarily complicated for the caller. Implement DisplayID iterators to go through all blocks in all sections. Usage example: const struct displayid_block *block; struct displayid_iter iter; displayid_iter_edid_begin(edid, &iter); displayid_iter_for_each(block, &iter) { /* operate on block */ } displayid_iter_end(&iter); When DisplayID is stored in EDID extensions, the DisplayID sections map to extensions as described in VESA DisplayID v1.3 Appendix B: DisplayID as an EDID Extension. This is implemented here. When DisplayID is stored in its dedicated DDC device 0xA4, according to VESA E-DDC v1.3, different rules apply for the structure. This is not implemented here, as we don't currently use it, but the idea is you'd have a different call for beginning the iteration, for example simply: displayid_iter_begin(displayid, &iter); instead of displayid_iter_edid_begin(), and everything else would be hidden away in the iterator functions. v2: - sizeof(struct displayid_block) -> sizeof(*block) (Ville) - remove __ prefix from displayid_iter_block Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/da3dead1752ab16c061f7bd248ac1a4268f7fefb.1617024940.git.jani.nikula@intel.com

2021-03-16drm: Add GUD USB Display driverNoralf Trønnes1-0/+333
This adds a USB display driver with the intention that it can be used with future USB interfaced low end displays/adapters. The Linux gadget device driver will serve as the canonical device implementation. The following DRM properties are supported: - Plane rotation - Connector TV properties There is also support for backlight brightness exposed as a backlight device. Display modes can be made available to the host driver either as DRM display modes or through EDID. If both are present, EDID is just passed on to userspace. Performance is preferred over color depth, so if the device supports RGB565, DRM_CAP_DUMB_PREFERRED_DEPTH will return 16. If the device transfer buffer can't fit an uncompressed framebuffer update, the update is split up into parts that do fit. Optimal user experience is achieved by providing damage reports either by setting FB_DAMAGE_CLIPS on pageflips or calling DRM_IOCTL_MODE_DIRTYFB. LZ4 compression is used if the device supports it.

2021-03-13linux/compiler-clang.h: define HAVE_BUILTIN_BSWAP*Arnd Bergmann1-0/+6
Separating compiler-clang.h from compiler-gcc.h inadventently dropped the definitions of the three HAVE_BUILTIN_BSWAP macros, which requires falling back to the open-coded version and hoping that the compiler detects it. Since all versions of clang support the __builtin_bswap interfaces, add back the flags and have the headers pick these up automatically. This results in a 4% improvement of compilation speed for arm defconfig. Note: it might also be worth revisiting which architectures set CONFIG_ARCH_USE_BUILTIN_BSWAP for one compiler or the other, today this is set on six architectures (arm32, csky, mips, powerpc, s390, x86), while another ten architectures define custom helpers (alpha, arc, ia64, m68k, mips, nios2, parisc, sh, sparc, xtensa), and the rest (arm64, h8300, hexagon, microblaze, nds32, openrisc, riscv) just get the unoptimized version and rely on the compiler to detect it. A long time ago, the compiler builtins were architecture specific, but nowadays, all compilers that are able to build the kernel have correct implementations of them, though some may not be as optimized as the inline asm versions. The patch that dropped the optimization landed in v4.19, so as discussed it would be fairly safe to backport this revert to stable kernels to the 4.19/5.4/5.10 stable kernels, but there is a remaining risk for regressions, and it has no known side-effects besides compile speed.

2021-03-13mm: introduce page_needs_cow_for_dma() for deciding whether cowPeter Xu1-0/+21
We've got quite a few places (pte, pmd, pud) that explicitly checked against whether we should break the cow right now during fork(). It's easier to provide a helper, especially before we work the same thing on hugetlbfs. Since we'll reference is_cow_mapping() in mm.h, move it there too. Actually it suites mm.h more since internal.h is mm/ only, but mm.h is exported to the whole kernel. With that we should expect another patch to use is_cow_mapping() whenever we can across the kernel since we do use it quite a lot but it's always done with raw code against VM_* flags.

2021-03-13mm/fork: clear PASID for new mmFenghua Yu1-0/+1
When a new mm is created, its PASID should be cleared, i.e. the PASID is initialized to its init state 0 on both ARM and X86. This patch was part of the series introducing mm->pasid, but got lost along the way [1]. It still makes sense to have it, because each address space has a different PASID. And the IOMMU code in iommu_sva_alloc_pasid() expects the pasid field of a new mm struct to be cleared.

2021-03-13stop_machine: mark helpers __always_inlineArnd Bergmann1-5/+6
With clang-13, some functions only get partially inlined, with a specialized version referring to a global variable. This triggers a harmless build-time check for the intel-rng driver: WARNING: modpost: drivers/char/hw_random/intel-rng.o(.text+0xe): Section mismatch in reference from the function stop_machine() to the function .init.text:intel_rng_hw_init() The function stop_machine() references the function __init intel_rng_hw_init(). This is often because stop_machine lacks a __init annotation or the annotation of intel_rng_hw_init is wrong. In this instance, an easy workaround is to force the stop_machine() function to be inline, along with related interfaces that did not show the same behavior at the moment, but theoretically could. The combination of the two patches listed below triggers the behavior in clang-13, but individually these commits are correct.

2021-03-13memblock: fix section mismatch warningArnd Bergmann1-2/+2
The inlining logic in clang-13 is rewritten to often not inline some functions that were inlined by all earlier compilers. In case of the memblock interfaces, this exposed a harmless bug of a missing __init annotation: WARNING: modpost: vmlinux.o(.text+0x507c0a): Section mismatch in reference from the function memblock_bottom_up() to the variable .meminit.data:memblock The function memblock_bottom_up() references the variable __meminitdata memblock. This is often because memblock_bottom_up lacks a __meminitdata annotation or the annotation of memblock is wrong. Interestingly, these annotations were present originally, but got removed with the explanation that the __init annotation prevents the function from getting inlined. I checked this again and found that while this is the case with clang, gcc (version 7 through 10, did not test others) does inline the functions regardless. As the previous change was apparently intended to help the clang builds, reverting it to help the newer clang versions seems appropriate as well. gcc builds don't seem to care either way.

Summary: - NVMe pull request: - one more quirk (Dmitry Monakhov) - fix max_zone_append_sectors initialization (Chaitanya Kulkarni) - nvme-fc reset/create race fix (James Smart) - fix status code on aborts/resets (Hannes Reinecke) - fix the CSS check for ZNS namespaces (Chaitanya Kulkarni) - fix a use after free in a debug printk in nvme-rdma (Lv Yunlong) - Follow-up NVMe error fix for NULL 'id' (Christoph) - Fixup for the bd_size_lock being IRQ safe, now that the offending driver has been dropped (Damien). - rsxx probe failure error return (Jia-Ju) - umem probe failure error return (Wei) - s390/dasd unbind fixes (Stefan) - blk-cgroup stats summing fix (Xunlei) - zone reset handling fix (Damien) - Rename BIO_MAX_PAGES to BIO_MAX_VECS (Christoph) - Suppress uevent trigger for hidden devices (Daniel) - Fix handling of discard on busy device (Jan) - Fix stale cache issue with zone reset (Shin'ichiro)" * tag 'block-5.12-2021-03-12-v2' of git://git.kernel.dk/linux-block: nvme: fix the nsid value to print in nvme_validate_or_alloc_ns block: Discard page cache of zone reset target range block: Suppress uevent for hidden device when removed block: rename BIO_MAX_PAGES to BIO_MAX_VECS nvme-pci: add the DISABLE_WRITE_ZEROES quirk for a Samsung PM1725a nvme-rdma: Fix a use after free in nvmet_rdma_write_data_done nvme-core: check ctrl css before setting up zns nvme-fc: fix racing controller reset and create association nvme-fc: return NVME_SC_HOST_ABORTED_CMD when a command has been aborted nvme-fc: set NVME_REQ_CANCELLED in nvme_fc_terminate_exchange() nvme: add NVME_REQ_CANCELLED flag in nvme_cancel_request() nvme: simplify error logic in nvme_validate_ns() nvme: set max_zone_append_sectors nvme_revalidate_zones block: rsxx: fix error return code of rsxx_pci_probe() block: Fix REQ_OP_ZONE_RESET_ALL handling umem: fix error return code in mm_pci_probe() blk-cgroup: Fix the recursive blkg rwstat s390/dasd: fix hanging IO request during DASD driver unbind s390/dasd: fix hanging DASD driver unbind block: Try to handle busy underlying device on discard

Pull io_uring fixes from Jens Axboe: "Not quite as small this week as I had hoped, but at least this should be the end of it. All the little known issues have been ironed out - most of it little stuff, but cancelations being the bigger part. Only minor tweaks and/or regular fixes expected beyond this point. - Fix the creds tracking for async (io-wq and SQPOLL) - Various SQPOLL fixes related to parking, sharing, forking, IOPOLL, completions, and life times. Much simpler now. - Make IO threads unfreezable by default, on account of a bug report that had them spinning on resume. Honestly not quite sure why thawing leaves us with a perpetual signal pending (causing the spin), but for now make them unfreezable like there were in 5.11 and prior. - Move personality_idr to xarray, solving a use-after-free related to removing an entry from the iterator callback. Buffer idr needs the same treatment. - Re-org around and task vs context tracking, enabling the fixing of cancelations, and then cancelation fixes on top. - Various little bits of cleanups and hardening, and removal of now dead parts" * tag 'io_uring-5.12-2021-03-12' of git://git.kernel.dk/linux-block: (34 commits) io_uring: fix OP_ASYNC_CANCEL across tasks io_uring: cancel sqpoll via task_work io_uring: prevent racy sqd->thread checks io_uring: remove useless ->startup completion io_uring: cancel deferred requests in try_cancel io_uring: perform IOPOLL reaping if canceler is thread itself io_uring: force creation of separate context for ATTACH_WQ and non-threads io_uring: remove indirect ctx into sqo injection io_uring: fix invalid ctx->sq_thread_idle kernel: make IO threads unfreezable by default io_uring: always wait for sqd exited when stopping SQPOLL thread io_uring: remove unneeded variable 'ret' io_uring: move all io_kiocb init early in io_init_req() io-wq: fix ref leak for req in case of exit cancelations io_uring: fix complete_post races for linked req io_uring: add io_disarm_next() helper io_uring: fix io_sq_offload_create error handling io-wq: remove unused 'user' member of io_wq io_uring: Convert personality_idr to XArray io_uring: clean R_DISABLED startup mess ...
