Subject: [PATCH 0/4] Emulator fixes to enable running NetBSD/alpha
Date: Sun, 13 Jun 2021 14:15:45 -0700	[thread overview]
Message-ID: <20210613211549.18094-1-thorpej@me.com> (raw)

The following are a set of fixes to device and system emulation that
allow NetBSD/alpha to run in qemu-system-alpha.

The first change fixes behavior in the mc146818rtc emulation to more
accurately reflect how the real hardware vis a vis the PF status bit
(specifically, that it is independent of the PIE control bit).  The
behavior of PF now matches the data sheet for the part.  This documented
behavior is relied upon by NetBSD/alpha to calibrate some timing loops.

The next two fix up a couple of aspects of the emulated device topology
for the "Clipper" system emulation.

The fourth passes console configuration information to the PALcode
at start-up, which in turn will reflect this information in the
Console Terminal Block to the guest operating system, and relies
on a corresponding PALcode change, although older PALcode will still
work if the "-nographics" option is not specified.

Jason Thorpe (4):
  mc146818rtc: Make PF independent of PIE
  alpha: Set minimum PCI device ID to 1 to match Clipper IRQ mappings.
  alpha: Provide a PCI-ISA bridge device node for guest OS's that expect
    it
  alpha: Provide console information to the PALcode at start-up.
