Wiatm
Mam router na gentoo. Wszystko bardzo fajnie działa, ale chciałem dzisiaj podkręcić dyski - bo jak przeżucam większe pliki na router to trwa to niemiłosiernie długo :(
i tak

Code: Select all

hdparm -d1 /dev/hda
/dev/hda:
 setting using_dma to 1 (on)
 HDIO_SET_DMA failed: Operation not permitted
 using_dma    =  0 (off)

Code: Select all

hdparm /dev/hda
/dev/hda:
 multcount    = 16 (on)
 IO_support   =  1 (32-bit)
 unmaskirq    =  1 (on)
 using_dma    =  0 (off)
 keepsettings =  0 (off)
 readonly     =  0 (off)
 readahead    = 32 (on)
 geometry     = 19386/16/63, sectors = 19541088, start = 0

Code: Select all

lspci |grep IDE
00:14.1 IDE interface: Intel Corporation 82371AB/EB/MB PIIX4 IDE (rev 01)
Ma ktoś z was może jakiś pomysł co z tym zrobić

Code: Select all

hdparm -Tt /dev/hda
/dev/hda:
 Timing cached reads:   556 MB in  2.01 seconds = 276.09 MB/sec
 Timing buffered disk reads:   24 MB in  3.08 seconds =   7.78 MB/sec
Te wyniki są straszne, a to mnie najbardziej drażni

Code: Select all

 HDIO_SET_DMA failed: Operation not permitted
Będę wdzięczny za pomoc

W jądrze włącz DMA...

Code: Select all

Device Drivers  --->  
ATA/ATAPI/MFM/RLL support  --->     
<*>   Enhanced IDE/MFM/RLL disk/cdrom/tape/floppy support          
[*]       Generic PCI bus-master DMA support      
[*]         Use PCI DMA by default when available
