2023-01-23vfio-mdev: remove an non-existing driver from vfio-mediated-deviceChristoph Hellwig
The nvidia mdev driver does not actually exist anywhere in the tree.

2023-01-13phy: Revert "phy: qualcomm: usb28nm: Add MDM9607 init sequence"Marijn Suijten
This reverts commit 557a28811c7e0286d3816842032db5eb7bb5f156. This commit introduced an init sequence from downstream DT [1] in the driver. As mentioned by the comment above the HSPHY_INIT_CFG macro for this sequence: /* * The macro is used to define an initialization sequence. Each tuple * is meant to program 'value' into phy register at 'offset' with 'delay' * in us followed. */ Instead of corresponding to offsets into the phy register, the sequence read by the downstream driver [2] is passed into ulpi_write [3] which crafts the address-value pair into a new value and writes it into the same register at USB_ULPI_VIEWPORT [4]. In other words, this init sequence is programmed into the hardware in a totally different way than downstream and is unlikely to achieve the desired result, if the hsphy is working at all. An alternative method needs to be found to write these init values at the desired location. Fortunately mdm9607 did not land upstream yet [5] and should have its compatible revised to use the generic one, instead of a compatible that writes wrong data to the wrong registers.

In commit 14243b387137a ("KVM: x86/xen: Add KVM_IRQ_ROUTING_XEN_EVTCHN and event channel delivery") the clever version of me left some helpful notes for those who would come after him: /* * For the irqfd workqueue, using the main kvm->lock mutex is * fine since this function is invoked from kvm_set_irq() with * no other lock held, no srcu. In future if it will be called * directly from a vCPU thread (e.g. on hypercall for an IPI) * then it may need to switch to using a leaf-node mutex for * serializing the shared_info mapping. */ mutex_lock(&kvm->lock); In commit 2fd6df2f2b47 ("KVM: x86/xen: intercept EVTCHNOP_send from guests") the other version of me ran straight past that comment without reading it, and introduced a potential deadlock by taking vcpu->mutex and kvm->lock in the wrong order. Solve this as originally suggested, by adding a leaf-node lock in the Xen state rather than using kvm->lock for it.

kvm->srcu is taken in KVM_RUN and several other vCPU ioctls, therefore vcpu->mutex is susceptible to the same deadlock that is documented for kvm->slots_lock. The same holds for kvm->lock, since kvm->lock is held outside vcpu->mutex.

Passing the host topology to the guest is almost certainly wrong and will confuse the scheduler. In addition, several fields of these CPUID leaves vary on each processor; it is simply impossible to return the right values from KVM_GET_SUPPORTED_CPUID in such a way that they can be passed to KVM_SET_CPUID2. The values that will most likely prevent confusion are all zeroes. Userspace will have to override it anyway if it wishes to present a specific topology to the guest.

2023-01-06docs: Deprecate use of Sphinx < 2.4.xJonathan Corbet
The Sphinx 2.4 release is three years old, and it is becoming increasingly difficult to even find a system with an sufficiently archaic Python installation that can run versions older than that. I can no longer test changes against anything prior to 2.4.x. Move toward raising our minimum Sphinx requirement to 2.4.x so we can delete some older support code and claim to support a range of versions that we can actually test. In the absence of screams, the actual removal of support can happen later in 2023. Signed-off-by: Jonathan Corbet <corbet@lwn.net>

2023-01-06arm64: errata: Workaround possible Cortex-A715 [ESR|FAR]_ELx corruptionAnshuman Khandual
If a Cortex-A715 cpu sees a page mapping permissions change from executable to non-executable, it may corrupt the ESR_ELx and FAR_ELx registers, on the next instruction abort caused by permission fault. Only user-space does executable to non-executable permission transition via mprotect() system call which calls ptep_modify_prot_start() and ptep_modify _prot_commit() helpers, while changing the page mapping. The platform code can override these helpers via __HAVE_ARCH_PTEP_MODIFY_PROT_TRANSACTION. Work around the problem via doing a break-before-make TLB invalidation, for all executable user space mappings, that go through mprotect() system call. This overrides ptep_modify_prot_start() and ptep_modify_prot_commit(), via defining HAVE_ARCH_PTEP_MODIFY_PROT_TRANSACTION on the platform thus giving an opportunity to intercept user space exec mappings, and do the necessary TLB invalidation. Similar interceptions are also implemented for HugeTLB.

power-domain is required for the sc7180 dispcc GDSC but not every qcom SoC has a similar dependency for example the apq8064. Most Qcom SoC's using mdss-dsi-ctrl seem to have the ability to power-collapse the MDP without collapsing DSI. For example the qcom vendor kernel commit for apq8084, msm8226, msm8916, msm8974. https://review.carbonrom.org/plugins/gitiles/CarbonROM/android_kernel_oneplus_msm8994/+/7b5c011a770daa2811778937ed646237a28a8694 "ARM: dts: msm: add mdss gdsc supply to dsi controller device It is possible for the DSI controller to be active when MDP is power collapsed. DSI controller needs to have it's own vote for mdss gdsc to ensure that gdsc remains on in such cases." This however doesn't appear to be the case for the apq8064 so we shouldn't be marking power-domain as required in yaml checks.

2023-01-05spi: dt-bindings: Rename spi-cs-setup-ns to spi-cs-setup-delay-nsHector Martin
Other delay values follow the delay-ns naming convention, so unify the newly introduced spi-cs-setup-ns property for consistency. Also fix a typo while we're here.

2023-01-05dt-bindings: interconnect: Add UFS clocks to MSM8996 A2NoCKonrad Dybcio
MSM8996 A2NoC contains a UFS master, which means the UFS hardware is accessed every time sync_state is called within the interconnect framework. It's all good on devices where this clock is already enabled (most likely from the bootloader), but devices with eMMC storage are rather unlikely to have it like that. Add the missing 2 clocks to the binding.

2023-01-05Merge branch kvm-arm64/s1ptw-write-fault into kvmarm-master/fixesMarc Zyngier
* kvm-arm64/s1ptw-write-fault: : . : Fix S1PTW fault handling that was until then always taken : as a write. From the cover letter: : : `Recent developments on the EFI front have resulted in guests that : simply won't boot if the page tables are in a read-only memslot and : that you're a bit unlucky in the way S2 gets paged in... The core : issue is related to the fact that we treat a S1PTW as a write, which : is close enough to what needs to be done. Until to get to RO memslots. : : The first patch fixes this and is definitely a stable candidate. It : splits the faulting of page tables in two steps (RO translation fault, : followed by a writable permission fault -- should it even happen). : The second one documents the slightly odd behaviour of PTW writes to : RO memslot, which do not result in a KVM_MMIO exit. The last patch is : totally optional, only tangentially related, and randomly repainting : stuff (maybe that's contagious, who knows)." : : .
