Mike Gerow 539ba3dcc9 Reland "devices: debugcon: add bochs-style debugcon device" ... This is a reland of commit 129840471d Original change's description: > devices: debugcon: add bochs-style debugcon device > > This allows for creating a simple write-only debug connection that uses > a single IO port. This method is supported by both bochs and qemu[1]. > > The main motivation here is to help in improving crosvm's ability to > boot OVMF, which makes use of this simple debug device on port 0x402. > For that one would use `--serial > type=stdout,hardware=debugcon,debugcon_port=1026` or something similar. > > Note that serde_keyvalue doesn't support parsing hex values, hence the > need to use `1026`, but I intend to address that as well to allow the > more natural `debugcon_port=0x402` phrasing. > > [1]: https://github.com/qemu/qemu/blob/master/hw/char/debugcon.c > > BUG=b:233610263 > > Change-Id: I73238e5c35925668d133bfaa542fcbcf1e28765f > Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/platform/crosvm/+/3661255 > Reviewed-by: Daniel Verkamp <dverkamp@chromium.org> > Commit-Queue: Mike Gerow <gerow@google.com> > Tested-by: kokoro <noreply+kokoro@google.com> Bug: b:233610263 Change-Id: I2f2125da95e8907f4f0c16930952e9b765d33e6c Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/platform/crosvm/+/3671087 Tested-by: kokoro <noreply+kokoro@google.com> Auto-Submit: Mike Gerow <gerow@google.com> Reviewed-by: Daniel Verkamp <dverkamp@chromium.org> Commit-Queue: Daniel Verkamp <dverkamp@chromium.org>		2022-05-26 19:25:02 +00:00
