Subject: [PATCH v3 0/2] mpt3sas: Additional retries when reading specific registers
Date: Wed, 26 Jul 2023 16:55:25 +0530 [thread overview]
Message-ID: <20230726112527.14987-1-ranjan.kumar@broadcom.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 689 bytes --]
Doorbell and Host diagnostic registers could return 0 even
after 3 retries and that leads to occasional resets of the
controllers, hence increased the retry count to thirty.
v1->v2:
-added a new patch for volatile as suggested by Greg KH.
-renamed macro as suggested by Damien Le Moal.
v2->v3:
-Modified patch description with more details.
Ranjan Kumar (2):
Perform additional retries if Doorbell read returns 0
mpt3sas: Removing volatile qualifier
