Map the device memory belonging to resources of type SYS_RES_MEMORY into KVA upon activation so that rman_get_virtual() works as expected. - In sbus_alloc_resource() checking whether toffs is 0 as an indication that no applicable child range was found isn't appropriate as it's perfectly valid for the requested SYS_RES_MEMORY resource to start at the beginning of a child range. So check for the RMAN still being NULL instead. - As a minor runtime speed optimization break out of the loop where we search for the applicable child range in sbus_alloc_resource() as soon as it's found. - Let sbus_setup_intr() return ENOMEM rather than 0 if it can't allocate memory for the interrupt clearing info. - Actually do what the comment in sbus_setup_intr() says and disable the respective interrupt while fiddling with it. - Remove some superfluous INTVEC() around inr, which already only contains the interrupt vector, in sbus_setup_intr(). - While here, fix a style(9) bug in sbus_setup_intr() (don't use function calls in initializers). The first two changes are required for a CG6 driver. MFC after: 2 weeks |
