[PATCH 0/6] tests/acceptance: Test the Fuloong 2E machine

[Philippe Mathieu-Daudé]

This series add tests for the MIPS Fuloong 2E machine.

I have been using these tests for over 1 year now.
After recent discussions with Huacai and Mark regarding
how to contribute tests for machines using private blob,
I think it is time to publish this series, to see how
the final part will be discussed, as it tests a blob
which Lemote company doesn't publish the sources. The
binary is know to work and has been used for various
years on real hardware. Its MD5 is also know (I am not
using SHA-1 because it has been published with MD5).

The idea is to be able to share tests without infringing
licenses issues.

Please comment :)

Phil.

[PATCH 2/6] tests/acceptance: Use .ppm extention for Portable PixMap files

[Philippe Mathieu-Daudé]

The HMP 'screendump' command generates Portable PixMap files.
Make it obvious by using the .ppm file extention.

Would it make sense to completely hide the tesseract version handling in
this new tesseract_utils.py file now, so that the tests themselves do not
have to worry about this anymore (i.e. would it be possible to merge
test_bootrom_framebuffer_ocr_with_tesseract_v3 and
test_bootrom_framebuffer_ocr_with_tesseract_v4 into one single test that way?)

If I've got that right, there is also now a proper release 4 of Tesseract,
so maybe we can simply scratch the testing with version 3 now?

Yes, good idea.

Good to know, I'll have a look. Thanks!

The problem is the recognized strings differ between versions,
see in tests/acceptance/machine_m68k_nextcube.py:

         lines = tesseract_ocr(screenshot_path, tesseract_version=3)
         text = '\n'.join(lines)
         self.assertIn('Backplane', text)
         self.assertIn('Ethernet address', text)

and:

         lines = tesseract_ocr(screenshot_path, tesseract_version=4)
         text = '\n'.join(lines)
         self.assertIn('Testing the FPU, SCC', text)
         self.assertIn('System test failed. Error code', text)
         self.assertIn('Boot command', text)
         self.assertIn('Next>', text)

Ah, right, I forgot about that ... well, one more reason to completely
switch to tesseract v4 now ;-)

[PATCH 6/6] tests/acceptance: Test PMON on the Fuloong 2E machine

[Philippe Mathieu-Daudé]

Test the PMON firmware. As the firmware is not redistributable,
it has to be downloaded manually first. Then it can be used by
providing its path via the PMON_BIN_PATH environment variable:

  $ PMON_BIN_PATH=~/images/fuloong2e/pmon_2e.bin \
    AVOCADO_ALLOW_UNTRUSTED_CODE=1 \

In general this looks good: certainly I don't see any reason why the tesseract_ocr 
helper changes shouldn't be merged, since I expect that this is something that will 
be used more in future.

Looking at the fuloong test it seems that it stops fairly early in the kernel boot: 
one of the problems that Zoltan's VIA southbridge patches were trying to solve 
earlier in the year was because of problems with PCI IRQ routing, so it would be nice 
to include a small OS image that can be used to boot to userspace to ensure that such 
problems can be detected in future.


ATB,

Mark.

The Linux tests (ab)use of the rescue image prepared for the Yeeloong
machine which we don't model (Loongson 2F CPU, 1GB of DRAM). The kernel
triggers DATA ABORT while accessing >256MB because we do not model
mapping more than 256MB :/ (The Fuloong comes with 512MB extensible to 
1GB). I have a branch adding that but had the idea nobody was interested
in the Fuloong 2E so I didn't insist (I have more interest in embedded
32-bit CPUs). I might try to post it after the release, as it makes this
test complete.

Thanks for giving it a try!

Phil.

I've noticed that missing high RAM when cleaning up SPD EEPROMs and addded 
a FIXME comment but did't know MIPS enough to attemt to fix it. Anyway I'm 
also only interested in fuloong2e as a test case for the devices also used 
by Pegasos2 (that I'll need to update and clean up to submit eventually) 
but not beyond that.

I haven't seen these patches before, so I've spotted only now that your 
test case uses -vga std. Shouldn't it work with ati-vga,model=rv100 which 
I think is the default for this machine and that's what the pmon firmware 
expects and has a driver for?

Dequeuing as Thomas already merged them.
