Thanks for your responses. The one with open/close seems to be the most reasonable. 23 сентября 2011, 23:06 от Jilles Tjoelker : > On Wed, Sep 21, 2011 at 04:23:28PM +0200, Ivan Voras wrote: > > On 21 September 2011 16:09, geoffrey levand wrote: > > > Sure i can use the synchronization primitive

The interface to the PS3 flash device is NOT like normal NOR/NAND flash interfaces. The interface to the PS3 FLASH is abstracted by the hypervisor and it looks like HDD to FreeBSD but has several logical units like SCSI devices. The flash device supports write, read and flush operation. Sector s

Could CAM framework be used for devices which do not support SCSI or ATA commands natively, e.g. FLASH devices ? I didn't find any examples for this case. I'm developing PS3 flash device driver. Or is disk framework better in this case ? I used CAM for PS3 CDROM driver but it supports SCSI comman
