Christian König authored
This patch adds an IOCTL for turning a pointer supplied by userspace into a buffer object. It imposes several restrictions upon the memory being mapped: 1. It must be page aligned (both start/end addresses, i.e ptr and size). 2. It must be normal system memory, not a pointer into another map of IO space (e.g. it must not be a GTT mmapping of another object). 3. The BO is mapped into GTT, so the maximum amount of memory mapped at all times is still the GTT limit. 4. The BO is only mapped readonly for now, so no write support. 5. List of backing pages is only acquired once, so they represent a snapshot of the first use. Exporting and sharing as well as mapping of buffer objects created by this function is forbidden and results in an -EPERM. v2: squash all previous changes into first public version v3: fix tabs, map readonly, don't use MM callback any more v4: set TTM_PAGE_FLAG_SG so that TTM never messes with the pages, pin/unpin pages on bind/unbind instead of populate/unpopulate v5: rebased on 3.17-wip, IOCTL renamed to userptr, reject any unknown flags, better handle READONLY flag, improve permission check v6: fix ptr cast warning, use set_page_dirty/mark_page_accessed on unpin v7: add warning about it's availability in the API definition v8: drop access_ok check, fix VM mapping bits Signed-off-by:

This reverts commit 48ba8137. Thanks to Chris: "drm_file->is_master is not synomous with having drm_file->master == drm_file->minor->master. This is because drm_file->master is the same for all drm_files of the same generation and so when there is a master, every drm_file believes itself to be the master. Confusion ensues and things go pear shaped when one file is closed and there is no master anymore." Conflicts: drivers/gpu/drm/drm_drv.c drivers/gpu/drm/drm_stub.c

drm/tegra: Changes for v3.17-rc1 Mostly some cleanup all over the place. Pitch alignment limitations of the display controller are now honored and job submission is 64-bit safe. The SOR output (used for eDP) properly configures sync signal polarities according to the display mode rather than hard-coding them to some value and the number of bits per color is now taken from the panel rather than hard-coded to properly support 24-bit vs. 18-bit panels. The DSI controller now properly supports non-continuous clock mode. GEM objects can now have their flags and tiling mode modified via IOCTLs to allow buffers imported from Nouveau to be properly displayed. Newer generations of the Tegra display controller can also detile block linear buffers at scan-out time. Finally the driver now properly exports MODULE_DEVICE_TABLEs to allow it to be automatically loaded when built as a module. * tag 'drm/tegra/for-3.17-rc1' of git://anongit.freedesktop.org/tegra/linux: drm/tegra: add MODULE_DEVICE_TABLEs drm/tegra: dc - Reset controller on driver remove drm/tegra: Properly align stride for framebuffers drm/tegra: sor - Configure proper sync polarities drm/tegra: sor - Use bits-per-color from panel drm/tegra: Make job submission 64-bit safe drm/tegra: Allow non-authenticated processes to create buffer objects drm/tegra: Add SET/GET_FLAGS IOCTLs drm/tegra: Add SET/GET_TILING IOCTLs drm/tegra: Implement more tiling modes drm/tegra: dsi - Handle non-continuous clock flag drm/tegra: sor - missing unlock on error

drm/panel: Changes for v3.17-rc1 Panels can now be more finely controlled via .prepare() and .unprepare() callbacks in addition to .enable() and .disable(). New kerneldoc details what they are supposed to do and when they should be called. The simple panel driver gained support for a couple of new panels and it is now possible to specify additional delays during power up and power down sequences if panels require it. DSI devices can now advertise that they support non-continuous clock mode which will allow DSI host controllers to disable the high speed clock after transmissions to save power. * tag 'drm/panel/for-3.17-rc1' of git://anongit.freedesktop.org/tegra/linux: (30 commits) drm/panel: simple: Use devm_gpiod_get_optional() drm/dsi: Replace upcasting macro by function drm/panel: ld9040: Replace upcasting macro by function drm/exynos: dp: Modify driver to support drm_panel drm/exynos: Move DP setup into commit() drm/panel: simple: Add AUO B133HTN01 panel support drm/panel: simple: Support delays in panel functions drm/panel: simple: Add proper definition for prepare and unprepare drm/panel: s6e8aa0: Add proper definition for prepare and unprepare drm/panel: ld9040: Add proper definition for prepare and unprepare drm/tegra: Add support for panel prepare and unprepare routines drm/exynos: dsi: Add support for panel prepare and unprepare routines drm/exynos: dpi: Add support for panel prepare and unprepare routines drm/panel: simple: Add dummy prepare and unprepare routines drm/panel: s6e8aa0: Add dummy prepare and unprepare routines drm/panel: ld9040: Add dummy prepare and unprepare routines drm/panel: Provide convenience wrapper for .get_modes() drm/panel: add .prepare() and .unprepare() functions drm/panel: simple: Remove simple-panel compatible drm/panel: simple: Add Innolux N116BGE panel support ...

Panels often require an initialization sequence that consists of three steps: a) powering up the panel, b) starting transmission of video data and c) enabling the panel (e.g. turn on backlight). This is usually necessary to avoid visual glitches at the beginning of video data transmission. Similarly, the shutdown sequence is typically done in three steps as well: a) disable the panel (e.g. turn off backlight), b) cease video data transmission and c) power down the panel. Currently drivers can only implement .enable() and .disable() functions, which is not enough to implement the above sequences. This commit adds a second pair of functions, .prepare() and .unprepare() to allow more fine-grained control over when the above steps are performed. Signed-off-by:

simple-panel is not a valid panel model, so there is no data (video timings, etc.) associated with it. Therefore drivers can't do anything useful with it, so it should not appear in the table of OF matches. Device trees will always need to specify the exact model of the panel. Signed-off-by: -

We need to take the connection mutex around the link status check for non-MST case, but also around the MST link training on short HPDs. I suspect we actually should have a dpcd lock in the future as well, that just lock the local copies of dpcd and flags stored from that. Reviewed-by:

For each minor we allocate a sysfs device as minor->kdev. Currently, this is allocated and registered in drm_minor_register(). This makes it impossible to add sysfs-attributes to the device before it is registered. Therefore, they are not added atomically, nor can we move device_add() *after* ->load() is called. This patch makes minor->kdev available early, but only adds the device during minor-registration. Note that the registration is still called before ->load() as debugfs needs to be split, too. This will be fixed in follow-ups. Reviewed-by:

Instead of allocating the minor-index during registration, we now do this during allocation. This way, debug-messages between minor-allocation and minor-registration will now use the correct minor instead of 0. Same is done for unregistration vs. free, so debug-messages between device-shutdown and device-destruction show proper indices. Even though minor-indices are allocated early, we don't enable minor lookup early. Instead, we keep the entry set to NULL and replace it during registration / unregistration. This way, the index is allocated but lookup only works if registered. Reviewed-by:

All that is left in drm_drv.c is ioctl management. Merge it into drm_ioctl.c so we have all ioctl management in one file (and the name is much more fitting). Maybe we should now rename drm_stub.c to drm_drv.c again? Acked-by:

Most of the new DRM management functions are nowadays in drm_stub.c. By moving the core module initialization to drm_stub.c we can make several global variables static and keep the stub-open helper local. The core files now look like this: drm_stub.c: Core management drm_drv.c: Ioctl dispatcher drm_ioctl.c: Actual ioctl backends drm_fops.c: Char-dev file-operations A follow-up patch will move what is left from drm_drv.c into drm_ioctl.c.

If an active DRM-Master closes its device, we deauthenticate all clients on that master. However, if an inactive DRM-Master closes its device, we do nothing. This is quite inconsistent and breaks several scenarios: 1) If this was used as security mechanism, it fails horribly if a master closes a device while VT switched away. Furthermore, none of the few drivers using ->master_*() callbacks seems to require it, anyway. 2) If you spawn weston (or any other non-UMS compositor) in background while another compositor is active, both will get assigned to the same "drm_master" object. If the foreground compositor now exits, all clients of both the foreground AND background compositor will be de-authenticated leading to unexpected behavior. Stop this non-sense and keep clients authenticated. We don't do this when dropping DRM-Master (i.e., switching VTs) so don't do it on active-close either! Reviewed-by: -

The drm_file->is_master field is redundant as it's equivalent to: drm_file->master && drm_file->master == drm_file->minor->master 1) "=>" Whenever we set drm_file->is_master, we also set: drm_file->minor->master = drm_file->master; Whenever we clear drm_file->is_master, we also call: drm_master_put(&drm_file->minor->master); which implicitly clears it to NULL. 2) "<=" minor->master cannot be set if it is non-NULL. Therefore, it stays as is unless a file drops it. If minor->master is NULL, it is only set by places that also adjust drm_file->is_master. Therefore, we can safely drop is_master and replace it by an inline helper that matches: drm_file->master && drm_file->master == drm_file->minor->master Reviewed-by: -

The ctxbitmap code is only used by legacy drivers so lets try to keep it as separated as possible. Furthermore, the locking is non-obvious and kinda weird with ctxlist_mutex *and* struct_mutex. Keeping all ctxbitmap access in one file is much easier to review and makes drm_release() more readable. Reviewed-by:
