Subject: [PATCH 0/2] Check VT-d Device-TLB flush error
Date: Thu, 17 Mar 2016 14:54:34 +0800 [thread overview]
Message-ID: <1458197676-60696-1-git-send-email-quan.xu@intel.com> (raw)
this patch set is a prereq patch set for Patch:'VT-d Device-TLB flush issue'.
Current code would be panic(), when VT-d Device-TLB flush timed out. the panic()
is going to be eliminated, so we must check all kinds of error and all the way up
the call trees.
Quan Xu (2):
IOMMU/MMU: Adjust top level functions for VT-d Device-TLB flush error.
IOMMU/MMU: Adjust low level functions for VT-d Device-TLB flush error.
This patch set was patch#1/patch#2 of 'VT-d Device-TLB flush issue' v6 patch sets.
--Changes in this version:
* Rebase against efc904263f483026672a5cdf3ccf9be8c4fdaa31.
* Make a reasonable attempt at splitting things, adjusting top level functions first and then
working the way down to leaf ones.
* Remove some pointless initializers (Compiler helps me check them).
* Log error and don't return error value for hardware_domain init and crashed system shutdown.
* when to populate iommu page table for domu, try to tear down the iommu page table for iommu
iotlb flush error.
* when the flush_iotlb_qi() return value is positive, All we need are:
-call iommu_flush_write_buffer() only when rc > 0
-return zero from this function when rc is positive (or 'rc = 0' after call iommu_flush_write_buffer()).
* Fix v4 "VT-d Device-TLB flush issue" unaddressed issue:
