2024-11-13octeontx2-pf: Get VF stats via representorGeetha sowjanya
Adds support to export VF port statistics via representor netdev. Defines new mbox "NIX_LF_STATS" to fetch VF hw stats. Signed-off-by: Geetha sowjanya <gakula@marvell.com> Reviewed-by: Simon Horman <horms@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2024-11-13octeontx2-af: Add packet path between representor and VFGeetha sowjanya
Current HW, do not support in-built switch which will forward pkts between representee and representor. When representor is put under a bridge and pkts needs to be sent to representee, then pkts from representor are sent on a HW internal loopback channel, which again will be punted to ingress pkt parser. Now the rules that this patch installs are the MCAM filters/rules which will match against these pkts and forward them to representee. The rules that this patch installs are for basic representor <=> representee path similar to Tun/TAP between VM and Host.

2024-11-13octeontx2-pf: RVU representor driverGeetha sowjanya
Adds basic driver for the RVU representor. Driver on probe does pci specific initialization and does hw resources configuration. Introduces RVU_ESWITCH kernel config to enable/disable the driver. Representor and NIC shares the code but representors netdev support subset of NIC functionality. Hence "otx2_rep_dev" API helps to skip the features initialization that are not supported by the representors.

2024-11-13Merge tag 'kvm-x86-misc-6.13' of https://github.com/kvm-x86/linux into HEADPaolo Bonzini
KVM x86 misc changes for 6.13 - Clean up and optimize KVM's handling of writes to MSR_IA32_APICBASE. - Quirk KVM's misguided behavior of initialized certain feature MSRs to their maximum supported feature set, which can result in KVM creating invalid vCPU state. E.g. initializing PERF_CAPABILITIES to a non-zero value results in the vCPU having invalid state if userspace hides PDCM from the guest, which can lead to save/restore failures. - Fix KVM's handling of non-canonical checks for vCPUs that support LA57 to better follow the "architecture", in quotes because the actual behavior is poorly documented. E.g. most MSR writes and descriptor table loads ignore CR4.LA57 and operate purely on whether the CPU supports LA57. - Bypass the register cache when querying CPL from kvm_sched_out(), as filling the cache from IRQ context is generally unsafe, and harden the cache accessors to try to prevent similar issues from occuring in the future. - Advertise AMD_IBPB_RET to userspace, and fix a related bug where KVM over-advertises SPEC_CTRL when trying to support cross-vendor VMs. - Minor cleanups

KVM VMX change for 6.13 - Remove __invept()'s unused @gpa param, which was left behind when KVM dropped code for invalidating a specific GPA (Intel never officially documented support for single-address INVEPT; presumably pre-production CPUs supported it at some point).

2024-11-13Merge tag 'kvm-x86-mmu-6.13' of https://github.com/kvm-x86/linux into HEADPaolo Bonzini
KVM x86 MMU changes for 6.13 - Cleanup KVM's handling of Accessed and Dirty bits to dedup code, improve documentation, harden against unexpected changes, and to simplify A/D-disabled MMUs by using the hardware-defined A/D bits to track if a PFN is Accessed and/or Dirty. - Elide TLB flushes when aging SPTEs, as has been done in x86's primary MMU for over 10 years. - Batch TLB flushes when zapping collapsible TDP MMU SPTEs, i.e. when dirty logging is toggled off, which reduces the time it takes to disable dirty logging by ~3x. - Recover huge pages in-place in the TDP MMU instead of zapping the SP and waiting until the page is re-accessed to create a huge mapping. Proactively installing huge pages can reduce vCPU jitter in extreme scenarios. - Remove support for (poorly) reclaiming page tables in shadow MMUs via the primary MMU's shrinker interface.
2024-11-13Merge tag 'kvm-x86-generic-6.13' of https://github.com/kvm-x86/linux into HEADPaolo Bonzini
KVM generic changes for 6.13 - Rework kvm_vcpu_on_spin() to use a single for-loop instead of making two partial poasses over "all" vCPUs. Opportunistically expand the comment to better explain the motivation and logic. - Protect vcpu->pid accesses outside of vcpu->mutex with a rwlock instead of RCU, so that running a vCPU on a different task doesn't encounter long stalls due to having to wait for all CPUs become quiescent.

Interrupts can be routed to maximal four virtual CPUs with real HW EIOINTC interrupt controller model, since interrupt routing is encoded with CPU bitmap and EIOINTC node combined method. Here add the EIOINTC virt extension support so that interrupts can be routed to 256 vCPUs in virtual machine mode. CPU bitmap is replaced with normal encoding and EIOINTC node type is removed, so there are 8 bits for cpu selection, at most 256 vCPUs are supported for interrupt routing.

2024-11-13ARM: 9431/1: mm: Pair atomic_set_release() with _read_acquire()Linus Walleij
The code for syncing vmalloc memory PGD pointers is using atomic_read() in pair with atomic_set_release() but the proper pairing is atomic_read_acquire() paired with atomic_set_release(). This is done to clearly instruct the compiler to not reorder the memcpy() or similar calls inside the section so that we do not observe changes to init_mm. memcpy() calls should be identified by the compiler as having unpredictable side effects, but let's try to be on the safe side.

2024-11-13usb: dwc3: gadget: Add missing check for single port RAM in TxFIFO resizing ↵Selvarasu Ganesan
logic The existing implementation of the TxFIFO resizing logic only supports scenarios where more than one port RAM is used. However, there is a need to resize the TxFIFO in USB2.0-only mode where only a single port RAM is available. This commit introduces the necessary changes to support TxFIFO resizing in such scenarios by adding a missing check for single port RAM. This fix addresses certain platform configurations where the existing TxFIFO resizing logic does not work properly due to the absence of support for single port RAM. By adding this missing check, we ensure that the TxFIFO resizing logic works correctly in all scenarios, including those with a single port RAM.
