| lkcl | octavius, great feedback on ls012 - look in the original csv file optable.csv | 09:21 |
|---|---|---|
| lkcl | but also, run the python script manually to generate the markdown tables, it's not automatic | 09:22 |
| lkcl | are you looking at the version where i've added the register profiles? | 09:24 |
| lkcl | bear in mind i'm doing 20+ edits a day sometimes so please make sure you always pull and rebuild then check that what you're about to write is still relevant | 09:25 |

| ghostmansd | lkcl, it seems that I cannot avoid doing at least some of the scope of task 1003 in scope of 976. One thing pulls another, that one pulls yet another one, and so on... | 17:43 |
| ghostmansd | In order to make things consistent, I have to update headers and sources which we generate... | 17:43 |
| ghostmansd | And, well, this beats the shit out of modes we deleted in Python classes... :-D | 17:43 |
| ghostmansd | This brings changes to disassembler and assembler... sigh. | 17:44 |
| ghostmansd | I'll try to keep the scope as tigh as possible, but some things are simply inevitable, unless I rewrite parts of autogenerated code, and this is certainly not the way I want to follow. | 17:44 |
| lkcl | ghostmansd, well, it is what it is. | 18:11 |
| lkcl | btw do see i updated power_insns.py | 18:12 |
| lkcl | and i also just removed (yesterday) RC1 mode from LD/ST DD-FFirst | 18:13 |
| ghostmansd[m] | lkcl, RC1 changes... They are not yet pushed, are they? | 18:15 |
| ghostmansd[m] | The last commit I see from you is Apr. 6 | 18:16 |
| lkcl | specification page - which is always the first place i edit (and then re-read 20-30 times) - is always pushed first | 18:27 |
| lkcl | as i made the removal only last night from the specification page, i haven't got round to editing power_insn.py | 18:30 |
| lkcl | (or updating power_decoder2.py which is always a pig, sigh) | 18:30 |
| ghostmansd | ah OK, I'll deal with it later then | 18:31 |
| ghostmansd | I'm updating modes tables | 18:32 |
| programmerjake | lkcl: i'm planning on updating the list of fptrans insn priorities today, some insns you marked as lower priority actually need to be high priority (e.g. min/max insns because min/max reductions need them and are pretty common) | 18:33 |
| programmerjake | also cuz fmin/fmax take like 10 insns to implement properly which is a lot | 18:35 |
| lkcl | daang | 18:36 |
| lkcl | i went off of the transcendentals page, and that wasn't on it. | 18:36 |
| lkcl | so please do update the transcendentals page *first* / simultaneously | 18:37 |
| programmerjake | uuh, it should be, iirc i added it... | 18:37 |
| programmerjake | not the fmin/max expense estimate, but the fmin/max insns themselves should be | 18:37 |
| lkcl | yes you'd added them, no you hadn't added what their priority is (which "optional subset") | 18:38 |
| programmerjake | ah | 18:39 |
| *** octavius <octavius!~octavius@92.40.169.97.threembb.co.uk> has joined #libre-soc | 18:41 | |
| lkcl | and guess where i copied the priorities from into the csv file? :) | 18:41 |
| programmerjake | imho they're quite cheap to implement in hw (about comparable to fp compare + some muxes) so should be in a subset on their own, most the other fptrans ops are waay more expensive | 18:43 |
| programmerjake | min/max and other newer will also need to be added to the lists of which insns other gpus have | 18:50 |
| programmerjake | newer ops | 18:50 |
| programmerjake | oh, do note that pow is commonly used in 3d graphics for computing specular highlights, so does need to be fast | 18:52 |
| programmerjake | see https://en.wikipedia.org/wiki/Phong_reflection_model | 18:56 |
| programmerjake | it's even in opengl 1.0 | 18:59 |
| programmerjake | well, actually https://en.wikipedia.org/wiki/Blinn%E2%80%93Phong_reflection_model which is closely related | 19:06 |

| knar | hi again, | 19:43 |
| knar | I was going through this [https://github.com/phaa-eu/cavatools.git] for compiling cavatools but ig the repos it links to has restructured a bit which i handled but i keep getting make errors. so ig my question would be is that the best link to get cavatools | 19:43 |

| lkcl | knar, as best i know, yes. | 20:28 |
| lkcl | programmerjake, do put that all into the notes. every instruction needs justification, and that's good stuff | 20:29 |
| programmerjake | will do, later today | 20:43 |
