[Qemu-devel] Would this introduce a competition?

[Richard Yang]

All

I am reading the code ohci_frame_boundary() and found it will get a copy
of the HCCA and process the interrupt ED list and then put it back.

I am afraid, during this processing period, the kernel driver(hcd) will
add other request to the interrupt ED list. 

So after qemu put the HCCA back, the new request will be overwriten?

BTW, how can I specify qemu to use ohci on x86 platform?
