Date: Thu, 24 Sep 2026 02:08:59 +0000 [thread overview]
Message-ID: <20260924020859.E61E01F000FF@smtp.kernel.org> (raw)
In-Reply-To: <20260924-spacemit-k1-pcie-fix-v1-1-002b5c1ba9fc@linux.spacemit.com>
> The K1 PCIe controller and PHY are affected by the PERST signal from
> the link partner during initialization. With some devices connected,
> this can prevent host initialization from progressing and cause the
> system to hang while probing the PCIe controller.
>
> Set PCIE_IGNORE_PERSTN before accessing the DBI registers. When set,
> this bit makes both the PCIe controller and PHY ignore the PERST
> signal from the link partner.
>
> This allows host initialization to complete without being affected by
> the link partner's PERST state.
