--- Comment #74 from [email protected] 2011-09-18 15:41:52 PDT --- OK Folks, it was just one bit, and it was unset by bios init tables. One Bit 0x400000 of register 0x4008, the register that responsible for memory clock. Actual values of this register: before suspend: 0x90596400 PCLOCK.MPLL1 => { UNK0 = 0x6400 | P = 0x1 | UNK19 = 0xb | UNK28 = 0x1 | ENABLE } after suspend: 0x90016400 PCLOCK.MPLL1 => { UNK0 = 0x6400 | P = 0x1 | UNK19 = 0 | UNK28 = 0x1 | ENABLE } test1: 0x90096400 - corruptions, but stable (with ctxfw, hang after 10 secs) test2 0x90516400 - good (with ctxprog) test3 0x90416400 - good (with ctxprog), without ctxprog: good test4 0x90116400 - corruptions without ctxprog Also seems that without nvidia's ctxprog, while we always got corruption, we didn't get hangs (but we tested just few laps of STK+glxgears) It doesn't matter much. It is one bit and its in unknown PLL area.... -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ Nouveau mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/nouveau
