Subject: [PATCH 0/4] OpenRISC fixes and setjmp/longjmp work
Date: Wed, 3 Mar 2021 22:50:22 +0900 [thread overview]
Message-ID: <20210303135026.3450789-1-shorne@gmail.com> (raw)
Hello,
These are the patches I came up with to get the setjmp/longjmp routines to work
on OpenRISC. It seems to be working well.
The patches are on github here:
https://github.com/stffrdhrn/barebox/tree/openrisc-bthread
I had to revert a commit to remove openrisc to do this work, I hope that can be
reverted.
Test output:
barebox@or1ksim:/ bthread -v
bthread_printer yield #1
bthread_printer yield #2
bthread_printer yield #3
bthread_printer yield #4
36441 bthread yield calls in 1s
barebox@or1ksim:/ bthread -v
bthread_printer yield #1
bthread_printer yield #2
bthread_printer yield #3
bthread_printer yield #4
36504 bthread yield calls in 1s
barebox@or1ksim:/ bthread
bthread - print info about registered bthreads
print info about registered barebox threads
Options:
-i Print information about registered bthreads
-t measure how many bthreads we currently run in 1s
-c count maximum context switches in 1s
-v verify correct bthread operation
barebox@or1ksim:/ bthread -c
bthread -c
269536 bthread context switches possible in 1s
