[Qemu-devel] Question

[Mohammed Al-Saleh]

Hi all;

I know that cd_read_sector function (which is called from 
ide_atapi_cmd_reply_end) in ide.c will copy data from the CD-ROM to an 
intermediate buffer, but I could not find out when this buffer is written to 
the RAM. All of what I can see is after reading data, ide_transfer_start and 
de_set_irq are called, but then what? how data will go to the RAM? if data 
will be copied to the RAM implicitly through the interrupt, then where can I 
find the ultimate function that copies the data to the RAM.
Can any body answer my question? it will be very appreciated.

Thanks,

...Mohammed
