To improve PCI performance on arm64 AWS instances, enable arch_can_pci_mmap_wc() via the patch:
From: Clint Sbisa <csbisa@amazon.com>
Subject: [PATCH] arm64: Enable PCI write-combine resources under sysfs
https://lore.kernel.org/linux-pci/20200831151827.pumm2p54fyj7fz5s@amazon.com/ |
To improve PCI performance on certain arm64 AWS instance types, enable arch_can_pci_mmap_wc() via the patch:
From: Clint Sbisa <csbisa@amazon.com>
Subject: [PATCH] arm64: Enable PCI write-combine resources under sysfs
https://lore.kernel.org/linux-pci/20200831151827.pumm2p54fyj7fz5s@amazon.com/
--------------
[Impact]
* AWS requires PCI-write-combine be enabled for arm64 via this one-line patch, to effect a significant performance improvement on certain AWS arm64 instance types.
* After considerable discussion, upstream indicates that this patch will be accepted into mainline[0] once additional documentation details get added to the commit description.
* Applying this patch to linux-aws affects only AWS arm64 instance types.
[Test Case]
* Has been performance-tested by AWS; smoke-tested by me.
[Regression Potential]
* Low.
