2019-07-21drm: Add Grain Media GM12U320 driver v2Hans de Goede6-0/+834
Add a modesetting driver for Grain Media GM12U320 based devices (primarily Acer C120 projector, but there may be compatible devices). This is based on the fb driver from Viacheslav Nurmekhamitov: https://github.com/slavrn/gm12u320 This driver uses drm_simple_display_pipe to deal with all the atomic stuff, gem_shmem_helper functions for buffer management and drm_fbdev_generic_setup for fbdev emulation, so that leaves the driver itself with only the actual code for talking to the gm12u320 chip, leading to a nice simple and clean driver. Changes in v2: -Add drm-misc tree to MAINTAINERS -Drop mode_config.preferred_depth = 24 / fix fbdev support Reviewed-by: Noralf Trønnes <noralf@tronnes.org> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190721132525.10396-1-hdegoede@redhat.com
2019-07-21drm/fb: remove unused function: drm_gem_fbdev_fb_create()Sam Ravnborg2-50/+0
After migrating several drivers to the generic fbdev emulation there are no users left of drm_gem_fbdev_fb_create. Delete the function. Noticed that there was no callers while browsing around in the drm_fb* code. The code that referenced the function was removed by: commit 13aff184ed9f ("drm/qxl: remove dead qxl fbdev emulation code") The actual use was removed by: commit 26d4707d445d ("drm/qxl: use generic fbdev emulation") v2: - Updated changelog based on feedback from Noralf Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Reviewed-by: Noralf Trønnes <noralf@tronnes.org> Cc: Gerd Hoffmann <kraxel@redhat.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20190721140610.GA20842@ravnborg.org

2019-07-21dt-bindings: riscv: Limit cpus schema to only check RiscV 'cpu' nodesRob Herring1-82/+61
Matching on the 'cpus' node was a bad choice because the schema is incorrectly applied to non-RiscV cpus nodes. As we now have a common cpus schema which checks the general structure, it is also redundant to do so in the Risc-V CPU schema. The downside is one could conceivably mix different architecture's cpu nodes or have typos in the compatible string. The latter problem pretty much exists for every schema.

2019-07-21dt-bindings: Ensure child nodes are of type 'object'Rob Herring6-0/+8
Properties which are child node definitions need to have an explict type. Otherwise, a matching (DT) property can silently match when an error is desired. Fix this up tree-wide. Once this is fixed, the meta-schema will enforce this on any child node definitions.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull CONFIG_PREEMPT_RT stub config from Thomas Gleixner: "The real-time preemption patch set exists for almost 15 years now and while the vast majority of infrastructure and enhancements have found their way into the mainline kernel, the final integration of RT is still missing. Over the course of the last few years, we have worked on reducing the intrusivenness of the RT patches by refactoring kernel infrastructure to be more real-time friendly. Almost all of these changes were benefitial to the mainline kernel on their own, so there was no objection to integrate them. Though except for the still ongoing printk refactoring, the remaining changes which are required to make RT a first class mainline citizen are not longer arguable as immediately beneficial for the mainline kernel. Most of them are either reordering code flows or adding RT specific functionality. But this now has hit a wall and turned into a classic hen and egg problem: Maintainers are rightfully wary vs. these changes as they make only sense if the final integration of RT into the mainline kernel takes place. Adding CONFIG_PREEMPT_RT aims to solve this as a clear sign that RT will be fully integrated into the mainline kernel. The final integration of the missing bits and pieces will be of course done with the same careful approach as we have used in the past. While I'm aware that you are not entirely enthusiastic about that, I think that RT should receive the same treatment as any other widely used out of tree functionality, which we have accepted into mainline over the years. RT has become the de-facto standard real-time enhancement and is shipped by enterprise, embedded and community distros. It's in use throughout a wide range of industries: telecommunications, industrial automation, professional audio, medical devices, data acquisition, automotive - just to name a few major use cases. RT development is backed by a Linuxfoundation project which is supported by major stakeholders of this technology. The funding will continue over the actual inclusion into mainline to make sure that the functionality is neither introducing regressions, regressing itself, nor becomes subject to bitrot. There is also a lifely user community around RT as well, so contrary to the grim situation 5 years ago, it's a healthy project. As RT is still a good vehicle to exercise rarely used code paths and to detect hard to trigger issues, you could at least view it as a QA tool if nothing else" * 'sched-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: sched/rt, Kconfig: Introduce CONFIG_PREEMPT_RT

2019-07-20x86/entry/64: Prevent clobbering of saved CR2 valueThomas Gleixner1-1/+10
The recent fix for CR2 corruption introduced a new way to reliably corrupt the saved CR2 value. CR2 is saved early in the entry code in RDX, which is the third argument to the fault handling functions. But it missed that between saving and invoking the fault handler enter_from_user_mode() can be called. RDX is a caller saved register so the invoked function can freely clobber it with the obvious consequences. The TRACE_IRQS_OFF call is safe as it calls through the thunk which preserves RDX, but TRACE_IRQS_OFF_DEBUG is not because it also calls into C-code outside of the thunk. Store CR2 in R12 instead which is a callee saved register and move R12 to RDX just before calling the fault handler.

2019-07-20KVM: Boost vCPUs that are delivering interruptsWanpeng Li3-5/+10
Inspired by commit 9cac38dd5d (KVM/s390: Set preempted flag during vcpu wakeup and interrupt delivery), we want to also boost not just lock holders but also vCPUs that are delivering interrupts. Most smp_call_function_many calls are synchronous, so the IPI target vCPUs are also good yield candidates. This patch introduces vcpu->ready to boost vCPUs during wakeup and interrupt delivery time; unlike s390 we do not reuse vcpu->preempted so that voluntarily preempted vCPUs are taken into account by kvm_vcpu_on_spin, but vmx_vcpu_pi_put is not affected (VT-d PI handles voluntary preemption separately, in pi_pre_block).

2019-07-20KVM: SVM: Fix detection of AMD Errata 1096Liran Alon1-7/+35
When CPU raise #NPF on guest data access and guest CR4.SMAP=1, it is possible that CPU microcode implementing DecodeAssist will fail to read bytes of instruction which caused #NPF. This is AMD errata 1096 and it happens because CPU microcode reading instruction bytes incorrectly attempts to read code as implicit supervisor-mode data accesses (that is, just like it would read e.g. a TSS), which are susceptible to SMAP faults. The microcode reads CS:RIP and if it is a user-mode address according to the page tables, the processor gives up and returns no instruction bytes. In this case, GuestIntrBytes field of the VMCB on a VMEXIT will incorrectly return 0 instead of the correct guest instruction bytes. Current KVM code attemps to detect and workaround this errata, but it has multiple issues: 1) It mistakenly checks if guest CR4.SMAP=0 instead of guest CR4.SMAP=1, which is required for encountering a SMAP fault. 2) It assumes SMAP faults can only occur when guest CPL==3. However, in case guest CR4.SMEP=0, the guest can execute an instruction which reside in a user-accessible page with CPL<3 priviledge. If this instruction raise a #NPF on it's data access, then CPU DecodeAssist microcode will still encounter a SMAP violation. Even though no sane OS will do so (as it's an obvious priviledge escalation vulnerability), we still need to handle this semanticly correct in KVM side. Note that (2) *is* a useful optimization, because CR4.SMAP=1 is an easy triggerable condition and guests usually enable SMAP together with SMEP. If the vCPU has CR4.SMEP=1, the errata could indeed be encountered onlt at guest CPL==3; otherwise, the CPU would raise a SMEP fault to guest instead of #NPF. We keep this condition to avoid false positives in the detection of the errata. In addition, to avoid future confusion and improve code readbility, include details of the errata in code and not just in commit message.

2019-07-20KVM: LAPIC: Inject timer interrupt via posted interruptWanpeng Li7-36/+87
Dedicated instances are currently disturbed by unnecessary jitter due to the emulated lapic timers firing on the same pCPUs where the vCPUs reside. There is no hardware virtual timer on Intel for guest like ARM, so both programming timer in guest and the emulated timer fires incur vmexits. This patch tries to avoid vmexit when the emulated timer fires, at least in dedicated instance scenario when nohz_full is enabled. In that case, the emulated timers can be offload to the nearest busy housekeeping cpus since APICv has been found for several years in server processors. The guest timer interrupt can then be injected via posted interrupts, which are delivered by the housekeeping cpu once the emulated timer fires. The host should tuned so that vCPUs are placed on isolated physical processors, and with several pCPUs surplus for busy housekeeping. If disabled mwait/hlt/pause vmexits keep the vCPUs in non-root mode, ~3% redis performance benefit can be observed on Skylake server, and the number of external interrupt vmexits drops substantially.
