Subject: [ISSUE] `cxl disable-region region0` twice but got same output
Date: Mon, 30 Oct 2023 14:41:36 +0800	[thread overview]
Message-ID: <dc013f7b-2039-e2ed-01ad-705435d16862@fujitsu.com> (raw)

Dear Linux Community Members,

I am writing to seek assistance with a issue that I have encountered 
while testing [Repeat executing the "cxl disable-region region0" 
command]. I have provided a detailed description of the problem along 
with relevant test for reference. I would greatly appreciate it if you 
could spare some time to help me resolve this issue.

Problem Description:

After investigation, it was found that when disabling the region and 
attempting to disable the same region again, the message "cxl region: 
cmd_disable_region: disabled 1 region" is still returned.
I consider this to be unreasonable.


Test Example:

[root@fedora-37-client memory]# cxl list
[
   {
     "memdevs":[
       {
         "memdev":"mem0",
         "ram_size":1073741824,
         "serial":0,
         "host":"0000:0d:00.0"
       }
     ]
   },
   {
     "regions":[
       {
         "region":"region0",
         "resource":27111981056,
         "size":1073741824,
         "type":"ram",
         "interleave_ways":1,
         "interleave_granularity":256,
         "decode_state":"commit"
       }
     ]
   }
]

[root@fedora-37-client ~]# cxl disable-region region0
cxl region: cmd_disable_region: disabled 1 region
[root@fedora-37-client ~]# cxl disable-region region0
cxl region: cmd_disable_region: disabled 1 region

expectation:cmd_disable_region: disabled 0 region


Thank you very much for taking the time to review my issue. I am 
grateful for your assistance and look forward to your response.

Best regards,
