Subject: [9fans] nvidia 7600GS works now
Topicbox-Message-UUID: d84ce50a-ead8-11e9-9d60-3106f5b1d025

I managed to work nVidia 7600GS (10de/0392) card for Plan 9.
As I don't know to whom I send this patch, and it's very small,
I decided to post it here.

/sys/src/cmd/aux/vga/nvidia.c should be changed as follows:

< 		case 0x0390:
---
> 		case 0x0390:	/* nvidia 7600 */

> 		nv->pramin[0x0818] = 0x0100805F;	/*WaitVSync not possible, if possible =0x01008062 */

< 					nv->pgraph[0x0608/4] |= 0x00100000;

< 				} else {
< 					nv->pgraph[0x09F0/4] = nv->pfb[0x0200/4];
< 					nv->pgraph[0x09F4/4] = nv->pfb[0x0204/4];

PS. nVidia 7950 card should work, too.
