2016-08-24Make console-log time more readable: seconds rather than timebaseBalbir Singh1-0/+5
I've tried to align it with what the kernel prints today The existing logs show: [20287269125,5] PSI[0x000]: Found PSI bridge [working=1, active=0] [890425679,5] BT: Interface initialized, IO 0x00e4 [1249199642,4] SLW: HB-provided idle states property found [1249344409,5] NVRAM: Size is 576 KB [1484422964,3] NVRAM: Layout appears sane The mftb() output is not very meaningful, the changed output shows: [ 38.315784591,5] CENTAUR: FSI host: 0x0 cMFSI0 port 2 [ 38.315922971,5] PSI[0x000]: Found PSI bridge [working=1, active=0] [ 1.448765255,5] BT: Interface initialized, IO 0x00e4 [ 2.398136129,5] NVRAM: Size is 576 KB [ 3.145017865,3] NVRAM: Layout appears sane For the output sample, I've taken bits where one can see the time move back w.r.t. previous log, but that was always the case. I don't think that is worth fixing here Adds an additional divide and modulo for every log printed. I've also fixed the test cases that run as a part of make check Signed-off-by: Balbir Singh <bsingharora@gmail.com> [stewart@linux.vnet.ibm.com: fix up tb in console tests] Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>
2016-07-06Timebase quirk for slow simulators like AWAN and SIMICSBenjamin Herrenschmidt1-1/+1
This will internally pretend the timebase is running 1000 times slower, which reduces some otherwise really terrible delays in some simulators.

2014-11-07timer: Add scheduled timer facilityBenjamin Herrenschmidt1-0/+2
For now running off the event pollers, that will improve once we get delayed interrupts from the SLW Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2014-08-13dpo: Add OPAL interface to access the DPO timeoutAnshuman Khandual1-0/+5
This patch adds a OPAL interface to fetch the DPO timeout. This functionality is required to synchronously query Sapphire about how much seconds are remaining for a forced system shutdown which is useful in cases where the host has missed the OPAL_MSG_DPO for some reason like system boot, reboot or kexec operations. This ensures host can still query about the DPO timeout status and act. This patch also adds helper routine to convert time base into seconds.
