Subject: Re: [PATCH V2 1/2] Swiotlb: Add swiotlb_alloc_from_low_pages switch
Date: Mon, 14 Feb 2022 09:19:19 +0100 [thread overview]
Message-ID: <20220214081919.GA18337@lst.de> (raw)
In-Reply-To: <20220209122302.213882-2-ltykernel@gmail.com>
Adding a function to set the flag doesn't really change much. As Robin
pointed out last time you should fine a way to just call
swiotlb_init_with_tbl directly with the memory allocated the way you
like it. Or given that we have quite a few of these trusted hypervisor
schemes maybe add an argument to swiotlb_init that specifies how to
allocate the memory.
