I also have memory related problems when loading big textures. When I try to use a ~717MB sized OpenGL 2D texture array, I get the following to the application's stderr (or stdout, haven't checked): > nouveau: kernel rejected pushbuf: Device or resource busy > nouveau: ch0: krec 0 pushes 1 bufs 10 relocs 0 > nouveau: ch0: buf 00000000 00000003 00000004 00000004 00000000 > nouveau: ch0: buf 00000001 00000010 00000002 00000000 00000002 > nouveau: ch0: buf 00000002 00000008 00000002 00000000 00000002 > nouveau: ch0: buf 00000003 00000013 00000002 00000002 00000002 > nouveau: ch0: buf 00000004 00000019 00000002 00000002 00000000 > nouveau: ch0: buf 00000005 00000011 00000002 00000000 00000002 > nouveau: ch0: buf 00000006 00000012 00000002 00000000 00000002 > nouveau: ch0: buf 00000007 00000015 00000002 00000002 00000000 > nouveau: ch0: buf 00000008 00000017 00000002 00000002 00000000 > nouveau: ch0: buf 00000009 00000014 00000002 00000000 00000002 > nouveau: ch0: psh 00000000 000004e6fc 000004eef4 And the kernel log reads: > [ 12.849796] nouveau [ DEVICE][0000:01:00.0] Chipset: GF119 (NVD9) > [ 12.849800] nouveau [ DEVICE][0000:01:00.0] Family : NVD0 > [ 13.584920] nouveau [ PFB][0000:01:00.0] RAM size: 1024 MiB ... > [ 328.496640] nouveau W[ PFIFO][0000:01:00.0] INTR 0x00000001: 0x00000000 > [ 328.496652] nouveau E[ PFIFO][0000:01:00.0] INTR 0x08800000 > [ 328.496689] nouveau E[ PBUS][0000:01:00.0] MMIO read of 0x00000000 FAULT at 0x002100 [ !ENGINE ] > [ 340.851380] nouveau E[ PFIFO][0000:01:00.0] read fault at 0x003a330000 [PAGE_NOT_PRESENT] from PGRAPH/DISPATCH on channel 0x003fb4e000 [DummyName[1554]] > [ 340.851386] nouveau E[ PFIFO][0000:01:00.0] PGRAPH engine fault on channel 3, recovering... > [ 344.331776] nouveau E[DummyName[1554]] nv50cal_space: -16 > [ 344.438226] nouveau E[DummyName[1554]] nv50cal_space: -16 > [ 344.544699] nouveau E[DummyName[1554]] nv50cal_space: -16 > [ 344.650491] nouveau E[DummyName[1554]] nv50cal_space: -16 > [ 344.756217] nouveau E[DummyName[1554]] nv50cal_space: -16 > [ 344.861902] nouveau E[DummyName[1554]] nv50cal_space: -16 > [ 344.969239] nouveau E[DummyName[1554]] nv50cal_space: -16 > [ 345.076069] nouveau E[DummyName[1554]] nv50cal_space: -16 > [ 345.183105] nouveau E[DummyName[1554]] nv50cal_space: -16 > [ 345.290630] nouveau E[DummyName[1554]] nv50cal_space: -16 > [ 345.398302] nouveau E[DummyName[1554]] nv50cal_space: -16 > [ 360.409590] nouveau E[DummyName[1554]] failed to idle channel 0xcccc0000 [DummyName[1554]] > [ 360.512756] nouveau E[DummyName[1554]] failed to idle channel 0xcccc0000 [DummyName[1554]]
