| stekern | juliusb: but you are not generating the overflow flag, right? | 05:39 |
|---|---|---|
| stekern | as long as you don't care about the overflow flag, smul and umul are equivalent for a 32x32 => 32 multiplier | 05:43 |
| stekern | i.e. the result in the lower 32-bits are always the same, the result in the upper 32-bit is the one that differs | 05:44 |
| stekern | olofk: since you were asking about my synth, here's an example of how it sounds: | 06:38 |
| stekern | http://oompa.chokladfabriken.org/tmp/delay_sample.mp3 | 06:38 |
| stekern | and here's a bit file for the atlys board: | 06:38 |
| stekern | http://oompa.chokladfabriken.org/tmp/SK_Synth-Atlys.bit | 06:38 |
| stekern | the sample mp3 is created only using the synth, no other external equipment (except a midi-cable) | 06:40 |
| aleck | hi everybody | 11:53 |
| aleck | is this the place for asking a couple of question about or1ksim? | 11:54 |
| _franck_ | aleck: yes it is | 11:57 |
| aleck | we have a problem setting a device from a generic section in the config file | 11:59 |
| aleck | i mean i set the baseaddr = 0x30000000 and size = 0x8 | 11:59 |
| aleck | but in the simulator if i run cat /proc/iomem | 12:00 |
| aleck | i don't see my device, what i am missing? | 12:00 |
| aleck | i mean i have followed the guide for building the toolchain, the simulator and linux | 12:00 |
| aleck | and they seems to work | 12:01 |
| aleck | with the standard configuration that i fount ind linux/arch/openrisc/or1ksim.cfg | 12:01 |
| _franck_ | your device needs to be probed by a driver to get mapped to the linux memory | 12:02 |
| _franck_ | linux cannot autodetect a device by itself (unless it is plug and play, like the pci bus) | 12:03 |
| aleck | thanks, so i can't register it directly from a module? | 12:03 |
| _franck_ | yes you can do it from a module | 12:04 |
| aleck | ok, so i go to read how to probe a device | 12:04 |
| aleck | thanks for the answer | 12:04 |
| olofk | stekern: That was fucking awesome. You should hook it up to the wishbone bus and run it together with a bump map, metaballs in tunnels and some star fields | 21:42 |
| olofk | juliusb: They want to know if our talk at fscons will be accessible. I think we can safely assume that isn't the case :) | 23:22 |
