2017-12-03core: Add support for quiescing OPALNicholas Piggin2-0/+66
Quiescing is ensuring all host controlled CPUs (except the current one) are out of OPAL and prevented from entering. This can be use in debug and shutdown paths, particularly with system reset sequences. This patch adds per-CPU entry and exit tracking for OPAL calls, and adds logic to "hold" or "reject" at entry time, if OPAL is quiesced. An OPAL call is added, to expose the functionality to Linux, where it can be used for shutdown, kexec, and before generating sreset IPIs for debugging (so the debug code does not recurse into OPAL).

2017-11-28xive: Implement "single escalation" featureBenjamin Herrenschmidt1-8/+21
This adds a new VP flag to control the new DD2.0 "single escalation" feature. This feature allows us to have a single escalation interrupt per VP instead of one per queue. It works by hijacking queue 7 (which is this no longer usable when that is enabled) and exploiting two new hardware bits that will: - Make the normal queues (0..6) escalate unconditionally thus ignoring the ESe bits. - Route the above escalations to queue 7 - Have queue 7 silently escalate without notification Thus the escalation of queue 7 becomes the one escalation interrupt for all the other queues.

2017-11-28xive: Define API for single-escalation VP modeBenjamin Herrenschmidt1-1/+21

As an immediate mitigator for a current hardware glitch, add a procedure that can be used to validate NTL credit values. This will be called as a safeguard to check that link training succeeded.

Add a new CPU reinit flag, "TM Suspend Disabled", which requests that CPUs be configured so that TM (Transactional Memory) suspend mode is disabled.

2017-10-11fsp: return OPAL_BUSY_EVENT on failure sending FSP_CMD_POWERDOWN_NORMStewart Smith2-4/+20
We had a race condition between FSP Reset/Reload and powering down the system from the host: Roughly: FSP Host --- ---- Power on Power on (inject EPOW) (trigger FSP R/R) Processes EPOW event, starts shutting down calls OPAL_CEC_POWER_DOWN (is still in R/R) gets OPAL_INTERNAL_ERROR, spins in opal_poll_events (FSP comes back) spinning in opal_poll_events (thinks host is running) The call to OPAL_CEC_POWER_DOWN is only made once as the reset/reload error path for fsp_sync_msg() is to return -1, which means we give the OS OPAL_INTERNAL_ERROR, which is fine, except that our own API docs give us the opportunity to return OPAL_BUSY when trying again later may be successful, and we're ambiguous as to if you should retry on OPAL_INTERNAL_ERROR. For reference, the linux code looks like this: >static void __noreturn pnv_power_off(void) >{ > long rc = OPAL_BUSY; > > pnv_prepare_going_down(); > > while (rc == OPAL_BUSY || rc == OPAL_BUSY_EVENT) { > rc = opal_cec_power_down(0); > if (rc == OPAL_BUSY_EVENT) > opal_poll_events(NULL); > else > mdelay(10); > } > for (;;) > opal_poll_events(NULL); >} Which means that *practically* our only option is to return OPAL_BUSY or OPAL_BUSY_EVENT. We choose OPAL_BUSY_EVENT for FSP systems as we do want to ensure we're running pollers to communicate with the FSP and do the final bits of Reset/Reload handling before we power off the system. Additionally, we really should update our documentation to point all of these return codes and what action an OS should take.
