* Kbuild : Use no-export-headers to avoid exporting headersNaitik Bharadiya2020-06-01
| | | | | | | | | | | | | Add header files under no-export-headers in Kbuild to avoid exporting specific headers files. Scan no-export-headers files in Kbuild and add it to exclude list in kernel_headers.py to avoid exporting header files.

* uapi: export all headers under uapi directoriesNicolas Dichtel2020-06-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Regularly, when a new header is created in include/uapi/, the developer forgets to add it in the corresponding Kbuild file. This error is usually detected after the release is out. In fact, all headers under uapi directories should be exported, thus it's useless to have an exhaustive list. After this patch, the following files, which were not exported, are now exported (with make headers_install_all): asm-arc/kvm_para.h asm-arc/ucontext.h asm-blackfin/shmparam.h asm-blackfin/ucontext.h asm-c6x/shmparam.h asm-c6x/ucontext.h asm-cris/kvm_para.h asm-h8300/shmparam.h asm-h8300/ucontext.h asm-hexagon/shmparam.h asm-m32r/kvm_para.h asm-m68k/kvm_para.h asm-m68k/shmparam.h asm-metag/kvm_para.h asm-metag/shmparam.h asm-metag/ucontext.h asm-mips/hwcap.h asm-mips/reg.h asm-mips/ucontext.h asm-nios2/kvm_para.h asm-nios2/ucontext.h asm-openrisc/shmparam.h asm-parisc/kvm_para.h asm-powerpc/perf_regs.h asm-sh/kvm_para.h asm-sh/ucontext.h asm-tile/shmparam.h asm-unicore32/shmparam.h asm-unicore32/ucontext.h asm-x86/hwcap2.h asm-xtensa/kvm_para.h drm/armada_drm.h drm/etnaviv_drm.h drm/vgem_drm.h linux/aspeed-lpc-ctrl.h linux/auto_dev-ioctl.h linux/bcache.h linux/btrfs_tree.h linux/can/vxcan.h linux/cifs/cifs_mount.h linux/coresight-stm.h linux/cryptouser.h linux/fsmap.h linux/genwqe/genwqe_card.h linux/hash_info.h linux/kcm.h linux/kcov.h linux/kfd_ioctl.h linux/lightnvm.h linux/module.h linux/nbd-netlink.h linux/nilfs2_api.h linux/nilfs2_ondisk.h linux/nsfs.h linux/pr.h linux/qrtr.h linux/rpmsg.h linux/sched/types.h linux/sed-opal.h linux/smc.h linux/smc_diag.h linux/stm.h linux/switchtec_ioctl.h linux/vfio_ccw.h linux/wil6210_uapi.h rdma/bnxt_re-abi.h Note that I have removed from this list the files which are generated in every exported directories (like .install or .install.cmd). Thanks to Julien Floret <julien.floret@6wind.com> for the tip to get all subdirs with a pure makefile command. For the record, note that exported files for asm directories are a mix of files listed by: - include/uapi/asm-generic/Kbuild.asm; - arch/<arch>/include/uapi/asm/Kbuild; - arch/<arch>/include/asm/Kbuild.

* drm: Pass CRTC ID in userspace vblank eventsAnder Conselvan de Oliveira2018-08-21
| | | | | | | | | | | | | | | | | | | | | | | | With the atomic API, it is possible that a single commit affects multiple crtcs. If the user requests an event with that commit, one event will be sent for each CRTC, but it is not possible to distinguish which crtc an event is for in user space. To solve this, the reserved field in struct drm_vblank_event is repurposed to include the crtc_id which the event is for. The DRM_CAP_CRTC_IN_VBLANK_EVENT is added to allow userspace to query if the crtc field will be set properly.

| | | | | | | | | | | | Add new remove framebuffer ioctl that simply unreferences the given framebuffer instead of triggering a shutdown of the CRTC if the buffer is in active use. This allows the user space to proactively unref the buffer without triggering an unwanted shutdown.

This works okay for simple cases but as applications become more complex we will want to set context specific flags and do various permisson checks to allow certain contexts to enable additional privileges. Add kernel-side submit queues to be analogous to 'contexts' or 'rendering queues' on the application side. Each file descriptor instance will maintain its own list of queues. Queues cannot be shared between file descriptors. For backwards compatibility context id '0' is defined as a default context specifying middle priority and no special flags. This is intended to be the usual configuration for 99% of applications so that a garden variety application can function correctly without creating a queue. Only those applications requiring the specific benefit of different queues need create one. In addition to the basic infrastructure, allow the user to specify the queue priority - this will be used in lieu of the legacy flags to set priority during the submission. Only the master DRM instance can set the highest priority, but all the others are open to all processes.

| * | drm/msm: Support secure rendering for A5XX targetsJordan Crouse2017-05-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A5XX targets support GPU rendering on secured surfaces by going into a special secure mode to execute the commands. In secure mode GPU rendering can only write to secure buffers that have been mapped in an appropriately secured pagetable. In secure mode the GPU can read both secure and unsecure buffers and the CP engine can only access unsecured buffers (so commands do not need to be secure). Secure buffers virtual addresses must fall into a specific range; this is the clue to the GPU that it should use the secure pagetable instead of the regular one. For A5XX targets that range will start at 0xC0000000 and be 256MB in size. All secure buffers in all processes share the same pagetable. Add a secure address space for A5XX targets and automatically trigger into secure mode if any buffer in the submission is marked as secure.

* | drm/msm: Add performance counter trackingJordan Crouse2017-03-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adreno GPUs have a certain number of fixed performance counters most of which can be programmed to a large number of different items (countables). A centralized database in the kernel is needed to make the most efficient use of counters across processes. Add performance counter tracking and APIs to allow applications to reserve performance counters by requesting a group ID and a countable (countables differ from block to block). The kernel will check to see if an active counter is already selected for that countable or if a new one should be assigned. Different processes can share the same counter if they both need the same countable. Counters are reserved with DRM_IOCTL_MSM_COUNTER_GET which returns a counter ID for the reserved counter and the hi/lo offset of the counter register. The reserving application can either read the counter from within a PM4 stream or it can use the group ID and counter ID and read the value of the counter with DRM_MSM_COUNTER_READ. After the counter is no longer needed DRM_IOCTL_MSM_COUNTER_PUT returns it and it can be released for other countables if no other processes are sharing it. Reservations are tracked for each process and cleaned up if the process dies without putting back the counters.
