[Qemu-devel] [RFC PATCH 0/2] docker: Add gentoo-mipsr5900el-cross image

["Philippe Mathieu-Daudé" <f4bug@amsat.org>]

Hi,

The first patch adds a cross toolchain for the R5900 MIPS.
It is working correctly but the patches provided by Fredrik in [1] don't
have proper S-o-b, thus it is tagged RFC.
Fredrik: any update on the status of those patches upstream?
I setup this image to try Fredrik's TCG tests in [2].

The second patch intents to have Shippable CI build the image and run the
TCG tests.
Since current idea of the Shippable tests is to cross-build QEMU for the
target, it does not work (and makes sense) here. I don't think there is
interest in running cross-compiled QEMU on a PS2... But we never know ;)
The failure I have is pkg-config using an incorrect path. I suppose I
am not using the CROSSDEV_OVERLAY path correctly.
Help from Gentoo developers would be appreciated!

I run the tests using:

$ docker-image-gentoo-mipsr5900el-cross
$ docker run --rm -it -v $PWD:$PWD \
    -w $PWD/tests/tcg/mips/mipsr5900 qemu:gentoo-mipsr5900el-cross \
    make all
$ make -C $PWD/tests/tcg/mips/mipsr5900 \
    check \
    SIM=$PWD/build/mipsel-softmmu/qemu-system-mipsel

With this minor modification:
