Subject: [PATCH v1 1/1] MiscBootServices: Stall_Func: Reduces the stall interval for Stall_Func
Date: Wed, 5 Oct 2022 07:55:46 -0700 [thread overview]
Message-ID: <20221005145546.176712-2-robwoo@google.com> (raw)
In-Reply-To: <20221005145546.176712-1-robwoo@google.com>
The Stall_Func test on the highest TPL causes issues with the disk IO by
blocking interrupts. This blocking can cause disk corruption through IO
timeouts. Since this doesn't seem to be the intent of the test this
revision reduces the stall interval from 10 seconds to 4 and adjusts the
delta tolerance in scale.
