very old qxl hardware revisions (predating qxl ksm support by a few years) supported a fixed list of video modes only.

2017-03-07drm: qxl: Don't alloc fbdev if emulation is not supportedGabriel Krisman Bertazi1-1/+8
If fbdev emulation is disabled, the QXL shutdown path will try to clean a framebuffer that wasn't initialized, hitting the Oops below. The problem is that even when FBDEV_EMULATION is disabled we allocate the qfbdev strutucture, but we don't initialize it. The fix is to stop allocating the memory, since it won't be used. This allows the existing verification in the cleanup hook to do it's job preventing the oops. Now that we don't allocate the unused fbdev structure, we need to be careful when dereferencing it in the PM suspend hook.

2017-03-05drm/bridge: Drivers for megachips-stdpxxxx-ge-b850v3-fw (LVDS-DP++)Peter Senna Tschudin3-0/+440
The video processing pipeline on the second output on the GE B850v3: Host -> LVDS|--(STDP4028)--|DP -> DP|--(STDP2690)--|DP++ -> Video output Each bridge has a dedicated flash containing firmware for supporting the custom design. The result is that in this design neither the STDP4028 nor the STDP2690 behave as the stock bridges would. The compatible strings include the suffix "-ge-b850v3-fw" to make it clear that the driver is for the bridges with the firmware which is specific for the GE B850v3. The driver is powerless to control the video processing pipeline, as the two bridges behaves as a single one. The driver is only needed for telling the host about EDID / HPD, and for giving the host powers to ack interrupts. This driver adds one i2c_device for each bridge, but only one drm_bridge. This design allows the creation of a functional connector that is capable of reading EDID from the STDP2690 while handling interrupts on the STDP4028.

Details: - An "nvdimm namespace label" is metadata on an nvdimm that provisions dimm capacity into a "namespace" that can host a block device / dax-filesytem, or a device-dax character device. A namespace is an object that other operating environment and platform firmware needs to comprehend for capabilities like booting from an nvdimm. The label metadata contains a checksum that Linux was not calculating correctly leading to other environments rejecting the Linux label. These have received a build success notification from the kbuild robot, and a positive test result from Nick who reported the problem" * 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: nfit, libnvdimm: fix interleave set cookie calculation tools/testing/nvdimm: make iset cookie predictable
