* Sometimes apt-get install qemu fails with fetch error, run apt-get
update first to mitigate
* unittest.py often fails due to app shell not started in 0.5s, increase
timeout
A large pile of changes to the PC platform and x86 architecture that
facilitate SMP support. Tested in both 64 and 32bit on qemu and real
hardware all the way back through i486.
This allows it to override the WERROR setting if, say, someone put
WERROR?=1 in their local.mk. (It's a good idea)
Note: I can't really leave WERROR enabled in the default build because
of all of the variants of compilers folks use in the wild, but I do
highly suggest folks use it locally.
This change introduces $LK_ROOT/toolchain as an official installation
directory for toolchains, as well as a new script for conveniently
installing them there (versus manual GETs + untarring).
getting_started.md is updated to suggest its use.
- Add the v9p support for arm platform.
- Add an option `-f` to set the shared directory on the host machine to
`do-qemuarm`.
- For example, to use the v9p dir sharing, run the script as:
```
# under `lk/` run the follow command will share the current
# directory `lk/` within LK vm as VirtIO 9p device
scripts/do-qemuarm -f .
```

In the non-QUIET case, the log function pipes output to the tee command.
Without the pipefail option, if a make command fails, but the tee exits
succesfully, the overall status is 0 and the failed project doesn't get
added to the FAILED list and reported. Adding the pipefail option
propagates the make failure appropriately and adds the target to the
FAILED list.
Updated comment regarding clobbers on the SBI call.
Tweak a boot time print of SBI version.
Add a commented out line to the do-qemuriscv to assist in dumping future
device trees.
This allows you to tag your build dirs with an optional string.
Update scripts/buildall to also allow building all release (DEBUG=0)
builds. Add a few other convenience switches.
If we were booted at EL2 (e.g. when passing -machine
virt,virtualization=on), we need to use SMC instead of HVC for PSCI
calls. Change psci_call() to do this and add a flag to do-qemuarm to
allow testing this scenario.
Wire them up on arm and riscv which need them. x86-pc does not, so dont
call it.
Also fix a few miscellaneous bugs, notably PCI not detecting 64bit bars
properly due to an off by one bit error.
Uses the QEMU virt machine for 68k defined in qemu 6.0+.
Basic support that boots, prints to the console, takes input from
console, and context switches.
TODO: interrupt support, timer support.
Use the new github actions to replace the travis-ci builders which
seem to no longer work and are being removed.
This first stab is fairly rough, just matches the explicit matrix
that was in the travis-ci hooks, but at least gets back to a buildable
state again.
Previous to now it had always relied on a custom patched gcc
and a custom sim. In the interim since the initial port went in
some time in 2015 GCC and QEMU have both officially picked up support
for the architecture and the machine that was emulated in the previous
emultor.
Using gcc 10.2 fix up the build and get it basically working. Timers
seem to not be working right but it's probably fairly easy to fix.
-Fix plic driver to handle machine vs supervisor mode
-Add switch to scripts/do-qemuriscv to run in supervisor mode (with OpenSBI)
-Use the FDT to detect the number of cpus and size of memory
Very little needed to port except to conditionalize some assembly in the
context switch and exception code. Mostly needed to move build system
stuff around and add a new project.
The virt machine is a generic target, much like the arm virt machine.
Intended to be simple to use and a good target to run large systems like
linux on. At the moment simply support booting and simple uart and timer
support.
