When trying to debug program, the user often needs to
dump large parts of the device's DRAM, which can reach to tens of GBs.
Because reading from the device's internal memory through the PCI BAR
is extremely slow, the debug can take hours.
Instead, we can provide the user to copy data through one of the DMA
engines. This will make the operation much faster.
Currently, only GAUDI is supported.
In GAUDI, we need to find a PCI DMA engine that is IDLE and set the
DMA as secured to be able to bypass our MMU as we currently don't
map the temporary buffer to the MMU.
Example bash one-line to dump entire HBM to file (~2 minutes):
for (( i=0x0; i < 0x800000000; i+=0x8000000 )); do \
printf '0x%x\n' $i | sudo tee /sys/kernel/debug/habanalabs/hl0/addr ; \
echo 0x8000000 | sudo tee /sys/kernel/debug/habanalabs/hl0/dma_size ; \
sudo cat /sys/kernel/debug/habanalabs/hl0/data_dma >> hbm.txt ; done

The commit 724fabf5df ("dt-bindings: phy: qcom,qmp-usb3-dp: Add DP phy
information") has support for DP part of USB3+DP combo PHYs. However
this change is not backwards compatible, placing additional requirements
onto qcom,sc7180-qmp-usb3-phy and qcom,sdm845-qmp-usb3-phy device nodes
(to include separate DP part, etc). However the aforementioned nodes do
not inclue DP part, they strictly follow the schema defined in the
qcom,qmp-phy.yaml file. Move those compatibles, leaving
qcom,qmp-usb3-dp-phy.yaml to describe only real "combo" USB3+DP device nodes.

On NVIDIA Carmel cores, CNP behaves differently than it does on standard
ARM cores. On Carmel, if two cores have CNP enabled and share an L2 TLB
entry created by core0 for a specific ASID, a non-shareable TLBI from
core1 may still see the shared entry. On standard ARM cores, that TLBI
will invalidate the shared entry as well.
This causes issues with patchsets that attempt to do local TLBIs based
on cpumasks instead of broadcast TLBIs. Avoid these issues by disabling
CNP support for NVIDIA Carmel cores.

Fix a plethora of issues with MSR filtering by installing the resulting
filter as an atomic bundle instead of updating the live filter one range
at a time. The KVM_X86_SET_MSR_FILTER ioctl() isn't truly atomic, as
the hardware MSR bitmaps won't be updated until the next VM-Enter, but
the relevant software struct is atomically updated, which is what KVM
really needs.
Similar to the approach used for modifying memslots, make arch.msr_filter
a SRCU-protected pointer, do all the work configuring the new filter
outside of kvm->lock, and then acquire kvm->lock only when the new filter
has been vetted and created. That way vCPU readers either see the old
filter or the new filter in their entirety, not some half-baked state.
Yuan Yao pointed out a use-after-free in ksm_msr_allowed() due to a
TOCTOU bug, but that's just the tip of the iceberg...
- Nothing is __rcu annotated, making it nigh impossible to audit the
code for correctness.
- kvm_add_msr_filter() has an unpaired smp_wmb(). Violation of kernel
coding style aside, the lack of a smb_rmb() anywhere casts all code
into doubt.
- kvm_clear_msr_filter() has a double free TOCTOU bug, as it grabs
count before taking the lock.
- kvm_clear_msr_filter() also has memory leak due to the same TOCTOU bug.
The entire approach of updating the live filter is also flawed. While
installing a new filter is inherently racy if vCPUs are running, fixing
the above issues also makes it trivial to ensure certain behavior is
deterministic, e.g. KVM can provide deterministic behavior for MSRs with
identical settings in the old and new filters. An atomic update of the
filter also prevents KVM from getting into a half-baked state, e.g. if
installing a filter fails, the existing approach would leave the filter
in a half-baked state, having already committed whatever bits of the
filter were already processed.
