When sigma0 runs on a lower priority than the rest of the threads in the
system it might come to the point that while answering a page fault or
I/O memory area request the timeslice of the caller (core-pager) gets
fully consumed. As long as other threads are still executable and don't block
sigma0 won't do progress anymore, because it runs at the lowest priority.
This commit simply sets sigma0's priority to the highest in the system.
This patch increases the size of the JDB kernel object names buffer. The
original size was too small for some Genode scenarios and caused missing
thread names in the kernel debugger thread list.
Fixes#191.
The syscall l4_task_cap_equal almost returns false although the referenced
kernel-objects are equal. This patch changes the semantic of the syscall so
that whenever two capabilities refering the same kernel-object are compared
it will return true. Please refer to the discussion of the following mail
thread:
