git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next Summary: . Add atomic feature support - Exynos also now supports atomic feature. However, it doesn't guarantee atomic operation yet, and is required for more cleanups. This time we just modified for Exynos drm driver to use atomic interfaces instead of legacy ones. Next time, we will enhance Exynos drm driver to support the atomic operation. . Add iommu support - This is a patch series according to below Exynos iommu integration work with DT and dma-mapping subsystem, http://lwn.net/Articles/607626/ . Consolidate Exynos drm driver initialization. - This patch sereis resolves the issue that only the first compoments was bound when happened deferred probing for other pipelines and also makes the driver to be more cleanned up by moving the dispered codes for registering kms drivers to one place. . Add new MIC, DECON drivers, and MIPI-DSI support for Exynos5433. - Add MIC(Mobile image compressor) driver. MIC is a new IP for Exynos5433 and later, which is used to transfer frame data to MIPI-DSI controller compressing the data to reduce memory bandwidth. - Add DECON driver for Exynos5433 SoC. This IP is a dislay controller similar to Exynos7's one but this controller has much different registers from Exynos7's ones so this driver has been implemented separately. We will implement a helper modules for FIMD and two DECON controllers to remove duplicated codes later. - Add Exynos5433 SoC support to MIPI-DSI driver, and device tree relevant patches. * 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos: (50 commits) ARM: dts: rename the clock of MIPI DSI 'pll_clk' to 'sclk_mipi' drm/exynos: dsi: do not set TE GPIO direction by input drm/exynos: dsi: add support for MIC driver as a bridge drm/exynos: dsi: add support for Exynos5433 drm/exynos: dsi: make use of array for clock access drm/exynos: dsi: make use of driver data for static values drm/exynos: dsi: add macros for register access drm/exynos: dsi: rename pll_clk to sclk_clk drm/exynos: mic: add MIC driver of: add helper for getting endpoint node of specific identifiers drm/exynos: add Exynos5433 decon driver drm/exynos: fix the input prompt of Exynos7 DECON drm/exynos: add drm_iommu_attach_device_if_possible() drm/exynos: Add the dependency for DRM_EXYNOS to DPI/DSI/DP drm/exynos: remove the dependency of DP driver for ARCH_EXYNOS drm/exynos: do not wait for vblank at atomic operation drm/exynos: Remove unused vma field of exynos_drm_gem_obj drm/exynos: fimd: fix page fault issue with iommu drm/exynos: iommu: improve a check for non-iommu dma_ops drm/exynos: iommu: detach from default dma-mapping domain on init ...

With dsi, not display port, to send frame data to the panel, the bandwidth is not enough. That is why this compressor is introduced.

git://anongit.freedesktop.org/drm-intel into drm-next One more round of drm-misc, again mostly atomic. Big thing is the userspace blob code from Daniel Stone, with support for the mode_id blob now added to the atomic ioctl. Finally we can do atomic modesets! Note that the atomic ioctl is still behind the module knob since the weston patches aren't quite ready yet imo - they lack TEST_ONLY support, which is a fairly crucial bit of the atomic api. But besides that I think it's all good to go. That's also why we didn't bother to hide the new blob ioctls behind the knob, that part won't need to change. And if weston patches get in shape in time we could throw the "atomic by default patch" on top for 4.2. * tag 'topic/drm-misc-2015-05-27' of git://anongit.freedesktop.org/drm-intel: drm: Fix off-by-one in vblank hardware counter wraparound handling drm/atomic: fix out of bounds read in for_each_*_in_state helpers drm/atomic: Add MODE_ID property drm/atomic: Add current-mode blob to CRTC state drm: Add drm_atomic_set_mode_for_crtc drm: check for garbage in unused addfb2 fields drm: Retain reference to blob properties in lookup drm/mode: Add user blob-creation ioctl drm: Return error value from blob creation drm: Allow creating blob properties without copy drm/mode: Unstatic kernel-userspace mode conversion drm/mode: Validate modes inside drm_crtc_convert_umode drm/crtc_helper: Replace open-coded CRTC state helpers drm: kerneldoc fixes for blob properties drm/DocBook: Add more drm_bridge documentation drm: bridge: Allow daisy chaining of bridges drm/atomic: add all affected planes in drm_atomic_helper_check_modeset drm/atomic: add drm_atomic_add_affected_planes drm/atomic: add commit_planes_on_crtc helper

2015-05-27drm/tilcdc: Add support for external tda998x encoderJyri Sarha
Add support for an external compontised DRM encoder. The external encoder can be connected to tilcdc trough device tree graph binding. The binding document for tilcdc has been updated. The current implementation supports only tda998x encoder. To be able to filter out the unsupported video modes the tilcdc driver needs to hijack the external connectors helper functions. The tilcdc installes new helper functions that are otherwise identical to orignals, but the mode_valid() call-back check the mode first localy, before calling the original call-back. The tilcdc dirver restores the original helper functions before it is unbound from the external device. I got the idea and some lines of code from Jean-Francois Moine's "drm/tilcdc: Change the interface with the tda998x driver"-patch.

2015-05-15Documentation: dt: mtd: replace "nor-jedec" binding with "jedec, spi-nor"Brian Norris
In commit 8ff16cf77ce3 ("Documentation: devicetree: m25p80: add "nor-jedec" binding"), we added a generic "nor-jedec" binding to catch all mostly-compatible SPI NOR flash which can be detected via the READ ID opcode (0x9F). This was discussed and reviewed at the time, however objections have come up since then as part of this discussion: http://lkml.kernel.org/g/20150511224646.GJ32500@ld-irv-0074 It seems the parties involved agree that "jedec,spi-nor" does a better job of capturing the fact that this is SPI-specific, not just any NOR flash. This binding was only merged for v4.1-rc1, so it's still OK to change the naming. At the same time, let's move the documentation to a better name. Next up: stop referring to code (drivers/mtd/devices/m25p80.c) from the documentation.

2015-05-11KVM: MMU: fix SMAP virtualizationXiao Guangrong
KVM may turn a user page to a kernel page when kernel writes a readonly user page if CR0.WP = 1. This shadow page entry will be reused after SMAP is enabled so that kernel is allowed to access this user page Fix it by setting SMAP && !CR0.WP into shadow page's role and reset mmu once CR4.SMAP is updated Signed-off-by: Xiao Guangrong <guangrong.xiao@linux.intel.com> Cc: stable@vger.kernel.org Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2015-05-10pty: Fix input race when closingPeter Hurley
A read() from a pty master may mistakenly indicate EOF (errno == -EIO) after the pty slave has closed, even though input data remains to be read. For example, pty slave | input worker | pty master | | | | n_tty_read() pty_write() | | input avail? no add data | | sleep schedule worker --->| | . |---> flush_to_ldisc() | . pty_close() | fill read buffer | . wait for worker | wakeup reader --->| . | read buffer full? |---> input avail ? yes |<--- yes - exit worker | copy 4096 bytes to user TTY_OTHER_CLOSED <---| |<--- kick worker | | **** New read() before worker starts **** | | n_tty_read() | | input avail? no | | TTY_OTHER_CLOSED? yes | | return -EIO Several conditions are required to trigger this race: 1. the ldisc read buffer must become full so the input worker exits 2. the read() count parameter must be >= 4096 so the ldisc read buffer is empty 3. the subsequent read() occurs before the kicked worker has processed more input However, the underlying cause of the race is that data is pipelined, while tty state is not; ie., data already written by the pty slave end is not yet visible to the pty master end, but state changes by the pty slave end are visible to the pty master end immediately. Pipeline the TTY_OTHER_CLOSED state through input worker to the reader. 1. Introduce TTY_OTHER_DONE which is set by the input worker when TTY_OTHER_CLOSED is set and either the input buffers are flushed or input processing has completed. Readers/polls are woken when TTY_OTHER_DONE is set. 2. Reader/poll checks TTY_OTHER_DONE instead of TTY_OTHER_CLOSED. 3. A new input worker is started from pty_close() after setting TTY_OTHER_CLOSED, which ensures the TTY_OTHER_DONE state will be set if the last input worker is already finished (or just about to exit). Remove tty_flush_to_ldisc(); no in-tree callers.
