Hi all, I'm trying to run Ruby in FS mode for the FFT benchmark. However, I've been unable to fully boot the kernel and error with a panic in the IDE disk controller: panic: Inconsistent DMA transfer state: dmaState = 2 devState = 1 @ cycle 62640732569001 [doDmaTransfer:build/ALPHA_FS_MOESI_CMP_directory/dev/ide_disk.cc, line 323]
Has anybody run into a similar error or does anyone have any suggestions for debugging the problem? I can run the same code using the M5 memory system and FFT finishes properly so it's definitely a ruby-specific thing. It seems to track this down , I could diff instruction traces (M5 v. Ruby) or maybe even diff trace output from the IdeDisk trace flags but those routes seem a bit heavy-handed considering the amount of trace output generated. The command line this was run with is: build/ALPHA_FS_MOESI_CMP_directory/m5.opt configs/example/ruby_fs.py -b fft_64t_base -n 1 The output in system.terminal is: hda: M5 IDE Disk, ATA DISK drive hdb: M5 IDE Disk, ATA DISK drive hda: UDMA/33 mode selected hdb: UDMA/33 mode selected hdc: M5 IDE Disk, ATA DISK drive hdc: UDMA/33 mode selected ide0 at 0x8410-0x8417,0x8422 on irq 31 ide1 at 0x8418-0x841f,0x8426 on irq 31 ide_generic: please use "probe_mask=0x3f" module parameter for probing all legacy ISA IDE ports ide2 at 0x1f0-0x1f7,0x3f6 on irq 14 ide3 at 0x170-0x177,0x376 on irq 15 hda: max request size: 128KiB hda: 2866752 sectors (1467 MB), CHS=2844/16/63 hda:<4>hda: dma_timer_expiry: dma status == 0x65 hda: DMA interrupt recovery hda: lost interrupt unknown partition table hdb: max request size: 128KiB hdb: 1008000 sectors (516 MB), CHS=1000/16/63 hdb:<4>hdb: dma_timer_expiry: dma status == 0x65 hdb: DMA interrupt recovery hdb: lost interrupt Thanks again, any help or thoughts would be well appreciated. -- - Korey _______________________________________________ m5-dev mailing list m5-dev@m5sim.org http://m5sim.org/mailman/listinfo/m5-dev
