build scripts for the WIP xenomai porting to kernel 5.4

build scripts for the WIP xenomai porting to kernel 5.4

[Fino Meng]

hi team,

I just updated the scripts to build the WIP version xenomai porting to
kernel 5.4, just follow the steps:

git clone https://github.com/finomeng/xenomai-mirror.git /tmp/xenomai-mirror.next-5.4
cd /tmp/xenomai-mirror.next-5.4
git checkout -t origin/wip/next-5.4-porting

git clone https://github.com/intel/linux-stable-xenomai /tmp/kernel
cd /tmp/kernel
git checkout -t review/5.4.59/stable/ipipe-x86

./patching-xenomai2kernel.sh

cp config_xenomai.kernel_debug .config
make olddefconfig
./build-debpkg.sh


I didn't put it togethter with ISAR/Debian yet. I test it with a PC with Debian 10 installed.

if no error, linux-image-*.deb and linux-headers-*.deb should generated outside kernel folder,
copy them to your target test device with already installed a Debian/Ubuntu,
install the deb with "dpkg -i", update-grub should be called during install linux-image-*.deb
reboot and select to boot the new kernel in grub's menu

the build steps also written in patching-xenomai2kernel.sh and build-debpkg.sh

switchtest will fail in current version, for example: "./switchtest rtk_fp_ufpp0"
will print:

r0: 2147483648 != 1000
r1: 2147483648 != 1000
r2: 2147483648 != 1000
r3: 2147483648 != 1000
r4: 2147483648 != 1000
r5: 2147483648 != 1000
r6: 2147483648 != 1000
r7: 2147483648 != 1000
ymm0: 2676586395008836901/0 != 1000/1000

ymm7: 1000/0 != 1000/1000
Error after context switch from task 1(rtk_fp_ufpp0-1) to task 0(sleeper_ufps0-0),
FPU registers were set to 0 (maybe task sleeper_ufps0-0)

if meet more questions just write to me, thanks!

I can reproduce in KVM and poked around a bit, though without finding
the needle yet. Likely, there are multiple aspects. The change in
upstream to FPU switching on user-return is a hot lead, but it takes a
bit to fully grasp that and map it on our scenarios with Xenomai.

Subplot: "switchtest --help" does not show the real help of that tool,
only "switchtest something-invalid". If someone is bored by debugging
the kernel, fixing that would also be appreciated!

it seems that, switch_fpu_prepare() and switch_fpu_finish() are
for kernel thread context switch (in __switch_to() )and switch_fpu_return() is needed
before return to userspace( in prepare_exit_to_usermode()).

Yes, we need explicit switch_fpu_return() (likely open-coded, to skip
the PF_KTHREAD check) at the end of xnarch_switch_to, at least as long
as we do not add that to all fast (primary-mode) return-to-user paths.

But it's more complex. The removal of fpu_initialized changed the
condition under which __switch_to() does FPU saving and restoring: All
kernel threads, also ours, are excluded. That needs to be compensated.

But I'm still facing corruptions - continuing to debug.

Quick update:

I made some progress with changes like below, but I'm still facing 
issues, not with weird AVX register corruptions. They confuse me because 
classic FPU registers are updated and saved/restored the same way, but 
they are currently unaffected.

in my current understand, 
a userspace Xenomai/Cobalt process's context switch always need FPU
state save/restore; but how about the other case?

in vanilla kernel, I see if a pure kernel thread want to use FPU, need
manually call kernel_fpu_begin() and kernel_fpu_end(), like a critical
area.

Xenomai kernel threads can use the FPU, and that without
kernel_fpu_begin/end. That this works is also tested by switchtest, and
there were several issues, possibly there are still more.

One step further: My weird avx register corruption is understand. It was
the local instrumentation. xnftrace_printf likely uses xmm regs
internally, and I had such an output after setting up the test pattern.
Fixing that, I still have a corruption, but not a "normal one" again,
ie. of the legacy FPU regs.

This still requires proper wrapping for the different kernel versions 
and some comments. But maybe you can continue testing from there.

I cannot reproduce it,

I use this config with IPIPE_DEBUG
https://github.com/intel/linux-stable-xenomai/blob/review/5.4.59/stable/ipipe-x86/config_xenomai.xeno_debug

test on a real WHL-U board (UP Xtreme), kernel boot OK and swtichtest
runs continously without error.

another config also have no error:
https://github.com/intel/linux-stable-xenomai/blob/review/5.4.59/stable/ipipe-x86/config_xenomai.kernel_debug

am I missing something? need to test the image inside QEMU/KVM? and this issue happens
during boot or after launch the switchtest?

This comes once during boot (in QEMU/KVM, but that should not matter -
famous last words). I have this set here:

CONFIG_IPIPE_DEBUG=y
CONFIG_IPIPE_DEBUG_CONTEXT=y
CONFIG_IPIPE_DEBUG_INTERNAL=y
CONFIG_HAVE_IPIPE_TRACER_SUPPORT=y
CONFIG_IPIPE_TRACE=y
# CONFIG_IPIPE_TRACE_ENABLE is not set
CONFIG_IPIPE_TRACE_MCOUNT=y
# CONFIG_IPIPE_TRACE_IRQSOFF is not set
CONFIG_IPIPE_TRACE_SHIFT=14
CONFIG_IPIPE_TRACE_VMALLOC=y
CONFIG_IPIPE_TRACE_PANIC=y

If you look at the source of the warning, you can see that
CONFIG_IPIPE_DEBUG_INTERNAL=y makes the difference.

in this version, xeno-test can successfully run until finish, log as
below.

be aware of RTNET and RTIPC part still have compile error, I didn't
enable them in .config yet. hope can fix them next week.

That's great. I'm currently rebasing things over 5.4.72 and also
starting to clean up / prepare for integration. Will likely require some
more rounds of reviews.

Do you recall why you switched from fpu__initialize to fpu__clear in
https://github.com/finomeng/xenomai-mirror/commit/59ab88aa0ddb109ae39572c7baacaaef68be86ce?

Yeah, that would be great!

actually no special reason, just thought fpu__initialize is not a export function
in vanilla kernel anymore. didn't check it's code.

Do you have patches for RTnet and Analogy already? RTIPC is fixed in
next. I'm currently trying to get CI fully running.

this morning, I didn't meet error when compile RTnet as module, strange.
for Analogy I didn't try yet, will try it today.

Happy to know RTIPC is done, I was checking it's code and make it pass compile like this:

I also tested hackbench:

it output errors, but the board is still alive.

latest ipipe-x86 + xenomai-next behaves much better than my previous
build, but still print similar error.

"hackbench -s 512 -l 200 -g 20 -f 50 -P" don't give error, which just
run once.

"while true; do taskset -c 1 hackbench -s 512 -l 200 -g 20 -f 50 -P;
done" will give error, it will keep folking and system pressure will bigger
and bigger; the way to stop it is keep pressing Ctrl-C. We use this
script as a torture method. 

the error appears in dmesg, after the script run for sometime. Test hardware
is UP Xtreme board (WHL8365UE).

I tested this script on Debian 10's original 4.19 kernel, no such error
appears in dmesg.

I'm also getting this, but first an OOM. I gave 4G to that machine, do
you have more?

Does the issue also happen with the same kernel when I-pipe is off?

I have 8G on board.

well, I pop off ipipe and xenomai patches, build a vanilla 5.4.72
kernel, the scripts also print such error. So maybe the issue is not
within ipipe/xenomai code~

That's what I was just about to do as well.

With I-pipe patches applied but disabled, I cannot avoid the OOM, even
with 8G. I did not get the RCU stall warning, though.

In any case, none of the internal lock-checker fired, neither on the
kernel nor I-pipe side. And the system remained operational after
killing hackbench. All good signs.
