Subject: [PATCH v2 0/2] SGX NUMA fix
Date: Thu, 5 Sep 2024 16:08:53 +0800 [thread overview]
Message-ID: <20240905080855.1699814-1-aaron.lu@intel.com> (raw)
Hi,
A soft lockup issue was found during some SGX testing and it turned
out to be a problem in SGX code related to NUMA, please see patch1/2
for details.
While Dave reviewed v1 of patch1/2, he suggested dumping an info when
a node has both CPUs and memory but no EPC section, so that's patch2/2.
Comments are welcome, thanks.
v2:
- Enhance changelog for patch1/2 according to Kai, Dave and Jarkko's
suggestions;
- Fix Reported-by tag, it should be Gerardo. Sorry for the mistake.
- Collect review tags.
- Add patch2/2.
