This panel is marketed as Banana Pi 7" LCD display. On the back is a sticker denoting the model name S070WV20-CT16. This is a 7" 800x480 panel connected through a 24-bit RGB interface. However the panel only does 262k colors. Depending on the variant, the PCB attached to the panel module either supports DSI, or DSI + 24-bit RGB. DSI is converted to 24-bit RGB via an onboard ICN6211 MIPI DSI - RGB bridge chip, then fed to the panel itself.

2018-09-20KVM: x86: Control guest reads of MSR_PLATFORM_INFODrew Schmitt1-0/+9
Add KVM_CAP_MSR_PLATFORM_INFO so that userspace can disable guest access to reads of MSR_PLATFORM_INFO. Disabling access to reads of this MSR gives userspace the control to "expose" this platform-dependent information to guests in a clear way. As it exists today, guests that read this MSR would get unpopulated information if userspace hadn't already set it (and prior to this patch series, only the CPUID faulting information could have been populated). This existing interface could be confusing if guests don't handle the potential for incorrect/incomplete information gracefully (e.g. zero reported for base frequency).

2018-09-14xen/balloon: add runtime control for scrubbing ballooned out pagesMarek Marczykowski-Górecki2-0/+15
Scrubbing pages on initial balloon down can take some time, especially in nested virtualization case (nested EPT is slow). When HVM/PVH guest is started with memory= significantly lower than maxmem=, all the extra pages will be scrubbed before returning to Xen. But since most of them weren't used at all at that point, Xen needs to populate them first (from populate-on-demand pool). In nested virt case (Xen inside KVM) this slows down the guest boot by 15-30s with just 1.5GB needed to be returned to Xen. Add runtime parameter to enable/disable it, to allow initially disabling scrubbing, then enable it back during boot (for example in initramfs). Such usage relies on assumption that a) most pages ballooned out during initial boot weren't used at all, and b) even if they were, very few secrets are in the guest at that time (before any serious userspace kicks in). Convert CONFIG_XEN_SCRUB_PAGES to CONFIG_XEN_SCRUB_PAGES_DEFAULT (also enabled by default), controlling default value for the new runtime switch.

git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper fixes from Mike Snitzer: - DM verity fix for crash due to using vmalloc'd buffers with the asynchronous crypto hadsh API. - Fix to both DM crypt and DM integrity targets to discontinue using CRYPTO_TFM_REQ_MAY_SLEEP because its use of GFP_KERNEL can lead to deadlock by recursing back into a filesystem. - Various DM raid fixes related to reshape and rebuild races. - Fix for DM thin-provisioning to avoid data corruption that was a side-effect of needing to abort DM thin metadata transaction due to running out of metadata space. Fix is to reserve a small amount of metadata space so that once it is used the DM thin-pool can finish its active transaction before switching to read-only mode. * tag 'for-4.19/dm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: dm thin metadata: try to avoid ever aborting transactions dm raid: bump target version, update comments and documentation dm raid: fix RAID leg rebuild errors dm raid: fix rebuild of specific devices by updating superblock dm raid: fix stripe adding reshape deadlock dm raid: fix reshape race on small devices dm: disable CRYPTO_TFM_REQ_MAY_SLEEP to fix a GFP_KERNEL recursion deadlock dm verity: fix crash on bufio buffer that was allocated with vmalloc

2018-09-12KVM: s390: Make huge pages unavailable in ucontrol VMsJanosch Frank1-1/+2
We currently do not notify all gmaps when using gmap_pmdp_xchg(), due to locking constraints. This makes ucontrol VMs, which is the only VM type that creates multiple gmaps, incompatible with huge pages. Also we would need to hold the guest_table_lock of all gmaps that have this vmaddr maped to synchronize access to the pmd. ucontrol VMs are rather exotic and creating a new locking concept is no easy task. Hence we return EINVAL when trying to active KVM_CAP_S390_HPAGE_1M and report it as being not available when checking for it.

2018-09-09drm: extract drm_atomic_uapi.cDaniel Vetter1-1/+10
This leaves all the commit/check and state handling in drm_atomic.c, while pulling all the uapi glue and the huge ioctl itself into a seprate file. This seems to almost perfectly split the rather big drm_atomic.c file into 2 equal sizes. Also adjust the kerneldoc and type a very terse overview text. v2: Rebase. v3: Fix tiny typo. v4: - Fixup armada, newly converted atomic driver hooray! - Fixup msm/dpu1, newly added too.
