Subject: [PATCH v1 0/2] swiotlb: Fix a couple of bugs in sizing areas
Date: Mon, 26 Jun 2023 15:01:02 +0200 [thread overview]
Message-ID: <cover.1687784289.git.petr.tesarik.ext@huawei.com> (raw)
From: Petr Tesarik <petr.tesarik.ext@huawei.com>
While reworking the dynamic SWIOTLB implementation, I ran into some
locking issues with the current implementation. I believe the bugs
are serious enough to be fixed separately.
Petr Tesarik (2):
swiotlb: Always set the number of areas before allocating the pool
swiotlb: Reduce the number of areas to match actual memory pool size
