Subject: [PATCH] iommuv2/amd: Add quirk for AMD 15H_M10 IOMMUv2 Performance
Counters
Add AMD PCI device definition that will identify devices that relate to the
IOMMUv2 PC PCI quirk added for potential non-enable by BIOS.
On AMD family 15h models 10h-1Fh BIOS may not enable performance counters in
IOMMUv2's EFR. Add a quirk to enable the counters when this happens.

Subject: [PATCH] iommuv2/amd: Enable Performance Counters On Family 15h
Models 10h-1Fh
Add Kernel configuration selection for AMD IOMMUv2 performance counters.
Add a check that will determine the configuration of the AMD IOMMUv2
performance counter(s) and extend the IOMMUv2 MMIO Region to account for the
additional PC register bank.
Add maximum IOMMUv2 bank/counter members to the amd_iommu structure that will
hold the relevant data concerning the available PC bank and counter resources.
Add code to iommu_init_pci that will check for IOMMUv2 PC HW support and
populate the max banks and counters into the amd_iommu structure.
Add exported functionality that will allow external drivers to obtain IOMMUv2
PC bank/counter resource information and manage the IOMMUv2 PC measurment
configuration. Bank and counter assignment is managed outside of this driver;
for example, within a perf IOMMUv2 PMU realization.

Hi Steven,
Hmm, the quirk looks quite familiar to me.
IMHO you should (re-?)read Documentation/SubmittingPatches.
(esp. no attachements, and btw one patch per mail)
Do you mind adding Joerg with his current (non-AMD) mail address on
CC? Otherwise it's impossible to get any comment from him.
Andreas

Hi Andreas,
This is your quirk, from AMD, and if you need to sign the patch please let me know how to facilitate this. I will add Joerg using his Email.
Thanks,
Steve

Subject: Re: Re-send the AMD IOMMUv2 performance counter patched and PCI quirk. Sorry for the noise.
Hi Steven,
Hmm, the quirk looks quite familiar to me.
IMHO you should (re-?)read Documentation/SubmittingPatches.
(esp. no attachements, and btw one patch per mail)
Do you mind adding Joerg with his current (non-AMD) mail address on CC? Otherwise it's impossible to get any comment from him.
Andreas

Please maintain the proper patch authorship. This is actually more
important than the Signed-off-by: sequence since this is a work for hire.
