| programmerjake | well, my build server randomly crashed for the 3rd or 4th time, I found no indication of what went wrong in any of the logs, and the temperature logging I added said the temperature was fine... | 02:28 |
|---|---|---|
| programmerjake | I'm thinking it's time to replace the motherboard and cpu with the ones from my old desktop ... even if piledriver is less likely to be able to be hacked/backdoored, having to constantly manually turn it on again is imho too much. also, the replacement system has more ram and is probably 2x faster. | 02:30 |
| programmerjake | lkcl: thank you for fixing the broken tests! | 02:47 |

| ghostmansd | lkcl, a quick question: why is self.insnlog established inside execute_one()? I suspect you circumvent it by using append mode for stream, but shouldn't we rather establish the stream before executing anything? | 14:29 |

| ghostmansd | programmerjake, lkcl, it seems that ISACaller is used not only by tests. I think nmutil.get_test_path is not a real option. How about creating a temporary file per ISA class instance? | 15:24 |
| vaino[m] | octavius: thanks, I'll check it out :) | 15:35 |

| octavius | ghostmansd, lkcl here : just pass in the filename as an option to ISACaller | 15:41 |
| octavius | (put it at the end on the list of arguments) | 15:41 |
| octavius | default to None | 15:41 |
| octavius | you get the idea | 15:41 |

| programmerjake | ghostmansd: just pass the filename into ISACaller and use nmutil.get_test_path in TestRunnerBase | 18:14 |
| programmerjake | inside the with self.subTest block | 18:15 |
| programmerjake | you may need to add a function to ISACaller to close the old file and open a new file with passed-in filename | 18:16 |

| lkcl | ghostmansd, eslf.insnlog is per-instruction, and i happen to know that execute_one() is the main "execute one instruction" entry-point | 20:42 |
| lkcl | https://git.libre-soc.org/?p=openpower-isa.git;a=blob;f=src/openpower/decoder/isa/pypowersim.py;h=fed3091f83ea7c19cbace36f65c02f7751be68d7;hb=1a96d4f3a63c17054c0f176909e3284c3b5c7831#l219 | 20:43 |
| lkcl | therefore, at the *start* of execute_one() the (copy of) the disassembled instruction is placed as the first (and only) entry, overwriting whatever was in it previously | 20:44 |
| lkcl | at various points within the "yield from self.call(opname)" additional "stuff" will be appended | 20:45 |
| lkcl | (registers read, registers written) | 20:45 |
| lkcl | and towards the end of execute_one you write out the entire contents of self.insnlog to the log file | 20:45 |
| lkcl | (only if self.insnlog_file has been initialised, obviously). | 20:45 |
| lkcl | open /tmp/inslog.txt is obviously intended as a proof-of-concept hack | 20:46 |
| lkcl | to be entirely replaced, but i wanted you to at least know *where* the replacement code should go | 20:47 |
| lkcl | as it's not immediately obvious | 20:47 |
