dagarm(4)

NAME
dagarm - Endace DAG card ARM memory access device

DESCRIPTION
/dev/dagarm0, /dev/dagarm1, /dev/dagarm2 are character devices representing ARM memory on the first, second, third etc. DAG cards detected by the operating system. At the time of writing the only supported DAG cards with ARM processors are the DAG 3.6D and DAG 3.5S.

Operations:

read
    Reads from ARM memory. Reads must be from a 32-bit aligned address and be a multiple of 32-bits in length.

write
    Writes to ARM memory. Writes must be to a 32-bit aligned address and be a multiple of 32-bits in length.

mmap
    Not implemented. ARM memory cannot be mapped into a process' virtual address space.

FILES
/dev/dagarm0, /dev/dagarm1, /dev/dagarm2, ...
