Misc stuff all over: - more mode_fixup removal from Carlos, there's another final pile still left. - final bits of vgaswitcheroo from Lukas for apple gmux, we're still discussing an api cleanup patch to make it a bit more abuse-safe as a follow-up - dp aux interface for userspace for tools&tests from Rafael Antognolli - actual interface parts for dma-buf flushing for userspace mmap - few small bits all over - vgaswitcheroo support for apple gmux from Lukas Wunner - checks for ->mode_fixup in non-atomic helpers from Carlos Palminha, plus removing dummy funcs from drivers. Carlos promised to follow up with more, since there's lots more silly dummy functions around. - dma-buf patches from Tiago, except the ioctl itself (that needed a respin to address review from David Herrmann) - encoder mask for atomic from Maarten - bunch of random things all over. * tag 'topic/drm-misc-2016-02-18' of git://anongit.freedesktop.org/drm-intel: (57 commits) drm/udl: Use module_usb_driver drm: fixes crct set_mode when crtc mode_fixup is null. drm/tilcdc: removed optional dummy encoder mode_fixup function. drm/sti: removed optional dummy encoder mode_fixup function. drm/rockchip: removed optional dummy encoder mode_fixup function. drm/qxl: removed optional dummy encoder mode_fixup function. drm/mgag200: removed optional dummy encoder mode_fixup function. drm/msm/mdp: removed optional dummy encoder mode_fixup function. drm/imx: removed optional dummy encoder mode_fixup function. drm/gma500: removed optional dummy encoder mode_fixup function. drm/radeon: removed optional dummy encoder mode_fixup function. drm/cirrus: removed optional dummy encoder mode_fixup function. drm/bochs: removed optional dummy encoder mode_fixup function. drm/ast: removed optional dummy encoder mode_fixup function. drm/amdgpu: removed optional dummy encoder mode_fixup function. drm/exynos: removed optional dummy encoder mode_fixup function. drm/udl: removed optional dummy encoder mode_fixup function. drm/virtio: removed optional dummy encoder mode_fixup function. drm/fb_helper: Use add_one_connector in add_all_connectors. drm/fb_helper: Use correct allocation count for arrays. ...

Macro module_usb_driver is used for drivers whose init and exit paths only register and unregister to usb API. So remove boilerplate code to make code simpler by using module_usb_driver. This change was made with the help of the following Coccinelle semantic patch: //<smpl> @A@ identifier f, x; @@ -static f(...) { return usb_register(&x); } @b depends on a@ identifier e, a.x; @@ -static e(...) { usb_deregister(&x); } @c depends on a && b@ identifier a.f; declarer name module_init; @@ -module_init(f); @d depends on a && b && c@ identifier b.e, a.x; declarer name module_exit; declarer name module_usb_driver; @@ -module_exit(e); +module_usb_driver(x); //</smpl> Signed-off-by:

So far, the i915 driver and some other drivers set it to the drm_device, which doesn't allow one to know which DP a given aux channel is related to. Changing this to be the drm_connector provides proper nesting, still allowing one to get the drm_device from it. Some drivers already set it to the drm_connector. This also removes the need to add a sysfs link for the i2c device under the connector, as it will already be there. v9: - As a side effect, drm_dp_aux_unregister() must be called before intel_connector_unregister(), as both the aux.dev and the i2c adapter dev are children of the drm_connector device now. Calling drm_dp_aux_unregister() before prevents them from being destroyed twice. v10: - move aux_fini() to connector_unregister(), instead of moving drm_dp_aux_unregister() outside of connector_register().

The userspace might need some sort of cache coherency management e.g. when CPU and GPU domains are being accessed through dma-buf at the same time. To circumvent this problem there are begin/end coherency markers, that forward directly to existing dma-buf device drivers vfunc hooks. Userspace can make use of those markers through the DMA_BUF_IOCTL_SYNC ioctl. The sequence would be used like following: - mmap dma-buf fd - for each drawing/upload cycle in CPU 1. SYNC_START ioctl, 2. read/write to mmap area 3. SYNC_END ioctl. This can be repeated as often as you want (with the new data being consumed by the GPU or say scanout device) - munmap once you don't need the buffer any more v2 (Tiago): Fix header file type names (u64 -> __u64) v3 (Tiago): Add documentation. Use enum dma_buf_sync_flags to the begin/end dma-buf functions. Check for overflows in start/length. v4 (Tiago): use 2d regions for sync. v5 (Tiago): forget about 2d regions (v4); use _IOW in DMA_BUF_IOCTL_SYNC and remove range information from struct dma_buf_sync. v6 (Tiago): use __u64 structured padded flags instead enum. Adjust documentation about the recommendation on using sync ioctls. v7 (Tiago): Alex' nit on flags definition and being even more wording in the doc about sync usage. v9 (Tiago): remove useless is_dma_buf_file check. Fix sync.flags conditionals and its mask order check. Add <linux/types.h> include in dma-buf.h.

This module is heavily based on i2c-dev. Once loaded, it provides one dev node per DP AUX channel, named drm_dp_auxN, where N is an integer. It's possible to know which connector owns this aux channel by looking at the respective sysfs /sys/class/drm_aux_dev/drm_dp_auxN/connector, if the connector device pointer was correctly set in the aux helper struct. Two main operations are provided on the registers read and write. The address of the register to be read or written is given using lseek. The seek position is updated upon read or write. v2: - lseek is used to select the register to read/write - read/write are used instead of ioctl - no blocking_notifier is used, just a direct callback v3: - use drm_dp_aux_dev prefix for public functions - chardev is named drm_dp_auxN - read/write don't allocate a buffer anymore, and transfer up to 16 bytes a time - remove notifier list from the implementation - option on menuconfig is now a boolean - add inline stub functions to avoid breakage when this option is disabled v4: - fix build system changes - actually disable this module when not selected. v5: - Use kref to avoid device closing while still in use - Don't use list, use an idr for storing aux_dev - Remove "connector" attribute - set aux.dev to the connector drm_connector device, instead of drm_device v6: - Use atomic_t for usage count - Use a mutex instead of spinlock for idr lock - Destroy chardev immediately on unregister - other minor suggestions from Ville v7: - style fixes - error handling fixes v8: - more error handling fixes v9: - remove module_init and module_exit, and add drm_dp_aux_dev_init/exit to drm_kms_helper_init/exit.
