Subject: [PATCH v7 1/5] PCI: Don't disable decoding when mmio_always_on is set
Date: Tue, 28 Apr 2020 09:14:16 +0800 [thread overview]
Message-ID: <20200428011429.1852081-2-jiaxun.yang@flygoat.com> (raw)
In-Reply-To: <20200428011429.1852081-1-jiaxun.yang@flygoat.com>
Don't disable MEM/IO decoding when a device have both non_compliant_bars
and mmio_always_on.
That would allow us quirk devices with junk in BARs but can't disable
their decoding.
