Hi,
I've just upgraded my PIII/800 from redhat 7.0 to redhat 8.0 with kernel 2.4.18-24.8.0. I'm using MPlayer-0.90rc4 with DXR3 (em8300-13.0) support.
Performance does not seem to be as good as it used to be. MPlayer is now much more sentitive to CPU load. Before I could compile a program or browse the web at the same time as watching a DIVX or DVD on my DXR3 without noticing any frames being dropped. Also, if I play DVDs, I can hear & see the sound & video stopping briefly for few milliseconds every few seconds even when there are no other cpu bound processes running.
What do I need to investigate in order to remedy this ?
hdparm
DMA settings are already enabled on all my IDE disks except for the DVD drive. [root]# dmesg | grep -i dvd hdc: ATAPI 40X DVD-ROM drive, 512kB Cache [root@gnu root]# hdparm -d 1 /dev/hdc /dev/hdc: setting using_dma to 1 (on) HDIO_SET_DMA failed: Operation not permitted using_dma = 0 (off) hum, dma cannot be set ! is this a feature ?
