Subject: Re: [PATCH v6 2/8] dma: swiotlb: Consolidate slab rounding
Date: Thu, 24 Sep 2026 06:19:42 +0000 [thread overview]
Message-ID: <20260924061943.7CF8E1F000FF@smtp.kernel.org> (raw)
In-Reply-To: <20260924060756.1325156-3-aneesh.kumar@kernel.org>
> Pass the area count explicitly to swiotlb_calc_nslabs() and keep the
> calculation separate from updates to the default_nslabs . Move the
> default_nslabs update into swiotlb_adjust_nareas().
>
> Round slabs to a power of two even before the area count is initialized.
> For early swiotlb_adjust_size() calls, this moves rounding from area
> initialization to size adjustment, so early queries see the rounded
> size.
