Subject: [PATCH 4.4 43/46] serial: 8250_pci: Add Realtek 816a and 816b
Date: Mon, 21 Sep 2020 18:27:59 +0200 [thread overview]
Message-ID: <20200921162035.255862443@linuxfoundation.org> (raw)
In-Reply-To: <20200921162033.346434578@linuxfoundation.org>
From: Tobias Diedrich <tobiasdiedrich@gmail.com>
commit 3c5a87be170aba8ac40982182f812dcff6ed1ad1 upstream.
These serial ports are exposed by the OOB-management-engine on
RealManage-enabled network cards (e.g. AMD DASH enabled systems using
Realtek cards).
Because these have 3 BARs, they fail the "num_iomem <= 1" check in
serial_pci_guess_board.
I've manually checked the two IOMEM regions and BAR 2 doesn't seem to
respond to reads, but BAR 4 seems to be an MMIO version of the IO ports
(untested).
With this change, the ports are detected:
0000:02:00.1: ttyS0 at I/O 0x2200 (irq = 82, base_baud = 115200) is a 16550A
0000:02:00.2: ttyS1 at I/O 0x2100 (irq = 55, base_baud = 115200) is a 16550A
lspci output:
