Subject: [PATCH 17/26] spl: Use map_sysmem where appropriate
Date: Wed, 11 Oct 2023 21:56:17 -0400 [thread overview]
Message-ID: <20231012015626.3487451-18-seanga2@gmail.com> (raw)
In-Reply-To: <20231012015626.3487451-1-seanga2@gmail.com>
All "physical" addresses in SPL must be converted to virtual addresses
before access in order for sandbox to work. Add some calls to map_sysmem in
appropriate places. We do not generally call unmap_sysmem, since we need
the image memory to still be mapped when we jump to the image. This doesn't
matter at the moment since unmap_sysmem is a no-op.
