Subject: [PATCH 12/15] Flush the TLB after idle operation
|
||
|
|
|
||
|
|
While a CPU executes the idle thread, it receives no cross-CPU TLB flush
|
||
|
|
requests. Therefore, the TLB needs to get flushed when leaving the idle
|
||
|
|
thread to compensate for any missed flush requests.
|
||
|
|
|
||
|
|
Fixes ssumpf/foc#9.
