- when CONFIG_DEBUG is enabled, track all threads
- when CONFIG_PRINTING is enabled, provide seL4_DebugDumpScheduler which
allows the user to dump the state of the kernel scheduler.
Prior to this commit faults were separate
per architecture. This commit extracts the common
fault types and introduces arch specific faults,
reducing code duplication across architectures.
This will update TCB invocations to consider multicore environment, this may include:
- adds the affinity invocation to transfer TCB between different cores and update TCB structure for core ID
- checking the thread/core state before performing TCB operation, e.g. deleting the runnable TCB, etc
Where MCP = Maximum Controlled Priority
This commit adds:
* seL4_TCB_SetMCPriority
and changes the arguments to
* seL4_TCB_Configure
As of this commit, a thread cannot create or set a threads
priority (including itself) above its mcp. Previously the kernel
did this check against a threads priority, which prevented a thread
from setting it's own priority down and then up again.
The previous macro computed to (0 - sizeof(tcb_t)). Basically a negative
number, which is just a really big unsigned number, so this macro was
basically allowing TCB naming of any length.
The previous definition of TCB_NAME_LENGTH assumed that the TCB was
split evenly into the cnode region and the rest. It did this by
calculating the size of the rest by using the size of the cnode
region. In actual fact the cnode region might be smaller, making
the size of the rest the size of the total tcb block size, minus
the cnode size. The max name length is therefore this region, minus
the size of the tcb_t
