|---|---|---|
| mntmn | oh? | 00:34 |
| _Bnu | Apparently the "pixel speed" thing for GetBestModeIDA is backwards, and it actively looks for a mode that is SLOWER OR EQUAL to the pixel speed (in nanoseconds) that the mode requires. | 00:34 |
| _Bnu | So setting the CLOCK_HZ to 25MHz instead of 100MHz makes them all work. | 00:34 |

| gdonner | _Bnu: thanks for your part in fixing that P96 GetBestModeIDA bug! | 17:00 |
| gdonner | I wonder if it was the kind of bug that led to crashes, or just failure to find a screen mode? | 17:01 |
| gdonner | either way, a GoodThing(TM) :) | 17:03 |

| _Bnu | gdonner: Oh, did it end up being a P96 bug? I figured it was just WB/AmigaOS, since P96 doesn't hook that function. | 17:28 |
| gdonner | Ah; wrong assumption on my part! My apologies. it should be fixed then in AmigaOS 3.2.1. | 17:32 |
| gdonner | Still, it's great these bugs are being found and get them fixed. | 17:33 |
| gdonner | especially something that impacts screen modes like that | 17:34 |
| _Bnu | Ah, nice. Yeah, apparently it's been around for 20+ years, haha. | 17:36 |
| _Bnu | Someone else had an issue with it when they had a 150Hz (?) screen mode set up for their Picasso IV, and in the end they just gave up and resorted to letting the user select the resolution from a dialog. | 17:37 |
| gdonner | perhaps one of the unfinished things C= was working on when they went bankrupt | 17:37 |
| gdonner | there were some cool things C= had in mind for the "real" 3.1; too bad they didn't get a chance to complete and test them properly | 17:39 |
| gdonner | http://gregdonner.org/workbench/wb_31_planned.html | 17:39 |
| _Bnu | It's sort of funny in a sad way to see Motorola's misstep with the 68k processor family there. | 17:45 |
| gdonner | yeah | 17:46 |
| gdonner | I wish they had at least taken it further than they did; one more big step after the 060 | 17:47 |
| _Bnu | For some reason my AdBlock isn't working on Google.com right now, making it completely unusable... | 17:51 |
| gdonner | the juicest details of what C= wanted to do (esp. OS-wise) are in the Orlando DevCon Notes, Jan. 26-30, 1993 | 17:51 |
| gdonner | hmm; maybe try Brave (web browser)? | 17:52 |
| _Bnu | Seriously, I get 20 pages of only ads, lol. | 17:52 |
| gdonner | yeah, it's getting ridiculous | 17:54 |
| gdonner | even sites like my local bank are using trackers | 17:54 |
| gdonner | thankfully Brave blocks them all | 17:54 |
| _Bnu | Or is something just wrong with Google? WTF. | 17:55 |
| _Bnu | I was going to search for the old MIPS index chart. | 17:55 |

| _Bnu | But it's seriously just helmets. | 17:56 |
| _Bnu | In the index chart over different processors, you could see the insane upward trend in performance up to the 68040... and then nothing. | 17:57 |
| gdonner | yeah, weird | 17:57 |
| gdonner | you would probably find the "RTG Graphics Specification" chapter interesting in those 1993 DevCon notes--quite a lot of detail | 18:03 |
| apolkosnik[m] | MIPS in helmets is a new innovation, basically a low friction surface between the inner part and the outer shell, supposedly helps | 18:13 |

| gdonner | _Bnu: If you like, I can file the GetBestModeIDA bug for you--any preferred wording you'd like me to use? | 20:08 |
| _Bnu | Oh, I thought maybe Michal had reported the bug already. | 20:11 |
| _Bnu | Basically "PixelSpeed" should be ignored completely when finding a suitable mode. It's not used uniformly across applications, so you can't rely on any value provided to check for is actually valid in any way. | 20:12 |
| gdonner | If he did, I didn't see anything when searching for "GetBestModeIDA"? | 20:14 |
| gdonner | what's his last name? | 20:14 |
| gdonner | (or maybe that is his last name) | 20:18 |
| gdonner | anyway, bug filed--let me know if anything else pops up | 20:21 |
| _Bnu | Ah, Michal Schulz, the Emu68 author/AROS guy. | 20:23 |
| gdonner | ok, thanks! but nothing came up from the search, so it should be OK. the bug number is 2261 if Michal wants to add or correct anything | 20:25 |
