there is a Bug that: vop_enable()->drm_vblank_on, drm_vblank_on may call vop enable vblank. if it happen, vblank enable would failed, then cause irq status error. because is_enabled value is set after drm_vblank_on. after enable vop clocks and iommu regs, we can sure that R/W vop regs and do vop plane flip is safe, so place is_enabled = true after enable iommu is suitable.

2015-03-16drm/rockchip: Only alloc a kmap for fbdev gem objectDaniel Kurtz
In general, the data in drm/rockchip GEM objects is never accessed by the kernel. The objects are either accessed by a GPU, by display controller DMA, or by mmap'ing them to user space. Thus, these buffers need not be mapped into kernel address space. The only exception is the fbdev framebuffer(s), which may be written in-kernel by fbcon.

2015-03-11drm/dp: Use large transactions for I2C over AUXSimon Farnsworth
Older DisplayPort to DVI-D Dual Link adapters designed by Bizlink have bugs in their I2C over AUX implementation (fixed in newer revisions). They work fine with Windows, but fail with Linux. It turns out that they cannot keep an I2C transaction open unless the previous read was 16 bytes; shorter reads can only be followed by a zero byte transfer ending the I2C transaction. Copy Windows's behaviour, and read 16 bytes at a time. If we get a short reply, assume that there's a hardware bottleneck, and shrink our read size to match. For this purpose, use the algorithm in the DisplayPort 1.2 spec, in the hopes that it'll be closest to what Windows does. Also provide an unsafe module parameter for testing smaller transfer sizes, in case there are sinks out there that cannot work with Windows. Note also that despite the previous comment in drm_dp_i2c_xfer, this speeds up native DP EDID reads; Ville Syrjälä <ville.syrjala@linux.intel.com> found the following changes in his testing: Device under test: old -> with this patch DP->DVI (OUI 001cf8): 40ms -> 35ms DP->VGA (OUI 0022b9): 45ms -> 38ms Zotac DP->2xHDMI: 25ms -> 4ms Asus PB278 monitor: 22ms -> 3ms A back of the envelope calculation shows that peak theoretical transfer rate for 1 byte reads is around 60 kbit/s; with 16 byte reads, this increases to around 500 kbit/s, which explains the increase in speed.

2015-03-10drm: Lighten sysfs connector 'status'Chris Wilson
Since the beginning, sysfs/connector/status has done a heavyweight detection of the current connector status. But no user, such as upowerd or logind, has ever desired to initiate a probe. Move the probing into a new attribute so that existing readers get the behaviour they desire. v2: David Herrmann suggested using "echo detect > /sys/.../status" to trigger the probing, which is a fine idea. This extends that to also allow the user to apply the force detection overrides at runtime. v3: Now with airlied's email address fixed!

2015-03-10drm: Fixup racy refcounting in plane_force_disableDaniel Vetter
Originally it was impossible to be dropping the last refcount in this function since there was always one around still from the idr. But in commit 83f45fc360c8e16a330474860ebda872d1384c8c Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Wed Aug 6 09:10:18 2014 +0200 drm: Don't grab an fb reference for the idr we've switched to weak references, broke that assumption but forgot to fix it up. Since we still force-disable planes it's only possible to hit this when racing multiple rmfb with fbdev restoring or similar evil things. As long as userspace is nice it's impossible to hit the BUG_ON. But the BUG_ON would most likely be hit from fbdev code, which usually invovles the console_lock besides all modeset locks. So very likely we'd never get the bug reports if this was hit in the wild, hence better be safe than sorry and backport. Spotted by Matt Roper while reviewing other patches.
