2017-06-28drm/vblank: Unexport drm_vblank_cleanupDaniel Vetter2-17/+3
There's no reason for drivers to call this, and all the ones I've removed looked very fishy: - Proper quiescenting of the vblank machinery should be done by calling drm_crtc_vblank_off(), which is best done by shutting down the entire display engine with drm_atomic_helper_shutdown. - Releasing of allocated memory is done by the core already, it calls drm_vblank_cleanup as a fallback. - drm_vblank_cleanup also has checks for drivers which forget to clean up vblank interrupts. This essentially reverts commit e77cef9c2d87db835ad9d70cde4a9b00b0ca2262 Author: Jerome Glisse <jglisse@redhat.com> Date: Thu Jan 7 15:39:13 2010 +0100 drm: Avoid calling vblank function is vblank wasn't initialized which was done to fix a bug in radeon code with msi interrupts: commit 003e69f9862bcda89a75c27750efdbc17ac02945 Author: Jerome Glisse <jglisse@redhat.com> Date: Thu Jan 7 15:39:14 2010 +0100 drm/radeon/kms: Don't try to enable IRQ if we have no handler installed Afaict from digging around in old code, this was needed to avoid blowing up in the ums fallback, and has stopped serving it's purpose long ago - if irq init fails, the driver fails to load, and there's really no way to blow up anymore. Long story short, this was most likely a small ums compat/fallback hack that became a thing of it's own and got cargo-cult duplicated all over the drm codebase for essentially no gain at all. v2: Mention that for drivers with a ->release callback cleanup is handled by drm_dev_fini() (Thierry).

2017-06-28drm/core: Fail atomic IOCTL with no CRTC state but with signaling.Andrey Grodzovsky1-1/+10
Problem : While running IGT kms_atomic_transition test suite i encountered a hang in drmHandleEvent immediately following an atomic_commit. After dumping the atomic state I relized that in this case there was not even one CRTC attached to the state and only disabled planes. This probably due to a commit which hadn't changed any property which would require attaching crtc state. This means drmHandleEvent will never wake up from read since without CRTC in atomic state the event fd will not be signaled. Fix: Protect against this issue by failing atomic_commit early in drm_mode_atomic_commit where such probelm can be identified. v2: Fix typos and extra newlines.

2017-06-23drm/vgem: Pin our pages for dmabuf exportsChris Wilson2-21/+64
When the caller maps their dmabuf and we return an sg_table, the caller doesn't expect the pages beneath that sg_table to vanish on a whim (i.e. under mempressure). The contract is that the pages are pinned for the duration of the mapping (from dma_buf_map_attachment() to dma_buf_unmap_attachment). To comply, we need to introduce our own vgem_object.pages_pin_count and elevate it across the mapping. However, the drm_prime interface we use calls drv->prime_pin on dma_buf_attach and drv->prime_unpin on dma_buf_detach, which while that does cover the mapping is much broader than is desired -- but it will do for now. v2: also hold the pin across prime_vmap/vunmap Reported-by: Tomi Sarvela <tomi.p.sarvela@intel.com> Testcase: igt/gem_concurrent_blit/*swap*vgem* Fixes: 5ba6c9ff961a ("drm/vgem: Fix mmaping") Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Tomi Sarvela <tomi.p.sarvela@intel.com> Cc: Laura Abbott <labbott@redhat.com> Cc: Sean Paul <seanpaul@chromium.org> Cc: Matthew Auld <matthew.auld@intel.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: <stable@vger.kernel.org> # needs a backport Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/20170622134617.17912-1-chris@chris-wilson.co.uk

Both drivers shut down all crtc beforehand already, which will shut up any pending vblank (the only thing vblank_cleanup really does is disable the disable timer). Hence we don't need this here and can remove it.

2017-06-23Input: synaptics-rmi4 - only read the F54 query registers which are usedAndrew Duggan1-10/+7
The F54 driver is currently only using the first 6 bytes of F54 so there is no need to read all 27 bytes. Some Dell systems (Dell XP13 9333 and similar) have an issue with the touchpad or I2C bus when reading reports larger then 16 bytes. Reads larger then 16 bytes are reported in two HID reports. Something about the back to back reports seems to cause the next read to report incorrect data. This results in F30 failing to load and the click button failing to work. Previous issues with the I2C controller or touchpad were addressed in: commit 5b65c2a02966 ("HID: rmi: check sanity of the incoming report") Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=195949 Signed-off-by: Andrew Duggan <aduggan@synaptics.com> Reviewed-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> Reviewed-by: Nick Dyer <nick@shmanahar.org> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

2017-06-23drm/rockchip: dw_hdmi: introduce the pclk for grfMark Yao1-0/+18
For RK3399's GRF module, if we want to operate the graphic related grf registers, we need to enable the pclk_vio_grf which supply power for VIO GRF IOs, so it's better to introduce an optional grf clock in driver.

2017-06-23drm/rockchip: dw_hdmi: introduce the VPLL clock settingMark Yao1-1/+24
For RK3399 HDMI, there is an external clock need for HDMI PHY, and it should keep the same clock rate with VOP DCLK. VPLL have supported the clock for HDMI PHY, but there is no clock divider bewteen VPLL and HDMI PHY. So we need to set the VPLL rate manually in HDMI driver.
