Hello everyone, I really like to use DMA for my cdrom/burner but I cant figure out how to make it working! I have a
hdc: HL-DT-ST DVD-RW GWA-4082N, ATAPI CD/DVD-ROM drive ide1 at 0x170-0x177,0x376 on irq 15 hdc: ATAPI 24X DVD-ROM DVD-R CD-R/RW drive, 2048kB Cache DMA is working fine for my disk but for cdrom I only get: tapa ~ # hdparm -d1 /dev/cdrom /dev/cdrom: setting using_dma to 1 (on) HDIO_SET_DMA failed: Operation not permitted using_dma = 0 (off) Does anyone of you know if there is DMA support for this cdrom-drive and if there is what to compile in the kernel? I already gave up to search ... because nothing wanted to work! Regards, Andreas Burghardt -- gentoo-user@gentoo.org mailing list
