* V4
- Now the conf files can use @TAP@, @ROOTFS@ and @PORT@ when set vars
for runqemu, so all the arch info are gone. And also update comments
in qemuboot.bbclass.
- Add var QB_SLIRP_OPT for slirp mode as Nathan suggested, also add
QB_TAP_OPT whichi is for tap mode.
- Print "Try 'runqemu help' on how to use it" when failed to parse args
as Nathan suggested.
- Fix device locking problems.
- Fix nativesdk-qemu-helper.
- Fix comments for qemurunner.py/qemutinyrunner.py
* V3
- Move the qemu boot settings out of tune files (e.g., arch-x86.inc)
to avoid mixing BSP settings with the tunings as Mark suggested. and
put them to <machine>.conf or <qemuboot>.inc file.
* V2
- Fixes for RP's comments
a) Remove a kvm commit message since qemu-kvm can only run target when
its arch is the same as the host arch:
The kvm support is not limited on x86 or x86_64
b) Fix a typo in commit message: qemu-boot.bbclass -> qemuboot.bbclass,
You may wonder why I use qemuboot.bbclass but not qemu-boot.bbclass,
this is because the bbclass will save vars into qemuboot.py, the
qemuboot.py can't be qemu-boot.py here, otherwise,
"import qemu-boot.py" doesn't work since "-" is not a validate
identifier, so use "qemuboot" to make them unify.
c) Reorder the patches to make sure they don't break the bisect build.
- Update commit message:
"Fix SLIRP mode" -> "Fix SLIRP mode, add help message, avoid mixing
with tap"
* V1
Previously, runqemu had hard coded machine knowledge, which limited its
usage, for example, qemu can boot genericx86, but runqemu can't, we need
edit runqemu/runqemu-internal a lot if we want to boot genericx86.
Now bsp conf files can set vars to make it can be boot by runqemu, and
qemuboot.bbclass will save these info to DEPLOY_DIR_IMAGE/qemuboot.py.
Please see qemuboot.bbclass' comments on how to set the vars.
- Re-write it in python3, which can reduce lines from 1239 to about 750
lines
- All the machine knowledges are gone
- All of the TUN_ARCH knowledge are gone (FIXED in V4)
- All the previous options are preserved, and there is a new way to run
runqemu: (it doesn't need run "bitake -e" in such a case)
$ runqemu tmp/deploy/images/qemux86
or:
$ runqemu tmp/deploy/images/qemuarm/<image>.ext4
or:
$ runqemu tmp/deploy/images/qemuarm/qemuboot.py
- Fixed audio support, not limited on x86 or x86_64
- The kvm support is not limited on x86 or x86_64 (REMOVED by V2)
- Fix SLIRP mode (FIXED by V2)
- Fix NFS boot, it will extract <image>.tar.bz2 or tar.gz to
DEPLOY_DIR_IMAGE/<image>-nfsroot when no NFS_DIR, and remove it after
stop.
- More bsps can be boot, such as genericx86 and genericx86-64.
- The patch for qemuzynq, qemuzynqmp, qemumicroblaze has been sent to
meta-xilinx' mailing list.
- I can't find any qemush4 bsp or how to build it, so it is not
considered atm.
- Tested the following machines, all of them work well.
genericx86 genericx86-64
qemuarm qemuarm64
qemumips qemumips64 qemuppc
qemux86 qemux86-64
qemuzynq qemuzynqmp
Tested ext4, nfs, slirp, vmdk, iso and cpio.gz when they are available.
And also test "bitbake core-image-sato -ctestimage" which uses runqemu,
it works, well.
