2018-08-27MGS-4162 [#imx-1143] fix suspend stuck with false negativeXianzhong
While investigating MLK-18894 ran a large number of suspend iterations on imx6qp-sdb with rc2 kernel. After ~6 hours it hung while suspending devices and sysrq-T showed the following trace for rtcwake: The gckHARDWARE_SetPowerManagementState function seems hung waiting for gckHARDWARE_QueryIdle. Inside the gckHARDWARE_QueryIdle there is a check which looks like this: rtcwake D 0 7090 561 0x00000001 [<809d5fc8>] (__schedule) from [<809d6380>] (schedule+0x48/0xb0) [<809d6380>] (schedule) from [<809d9d3c>] (schedule_hrtimeout_range_clock+0xc8/0x13c) [<809d9d3c>] (schedule_hrtimeout_range_clock) from [<809d9df0>] (schedule_hrtimeout+0x20/0x28) [<809d9df0>] (schedule_hrtimeout) from [<807168c4>] (gckOS_Delay.part.3+0x64/0x6c) [<807168c4>] (gckOS_Delay.part.3) from [<8071813c>] (gckOS_Delay+0x18/0x20) [<8071813c>] (gckOS_Delay) from [<8073f08c>] (gckHARDWARE_SetPowerManagementState+0x838/0xb70) [<8073f08c>] (gckHARDWARE_SetPowerManagementState) from [<8071df18>] (gpu_suspend+0x74/0xe4) [<8071df18>] (gpu_suspend) from [<804fb9e8>] (dpm_run_callback+0x3c/0xdc) /* Test if address is inside the last WAIT/LINK sequence. */ if ((address >= Hardware->lastWaitLink) && (address <= Hardware->lastWaitLink + 16) Stepping through using the debugger (screenshot attached) this function seems to return non-idle with both address lastWaitLink and being equal to 0xFFFFFFF0. As far as I can tell the intention seems to be that the check should pass but 0xFFFFFFF0 + 16 overflows back to zero so the second part of the check fails because 0xFFFFFFF0 is not less than or equal to 0. Adding some prints to GPU code it seems that it's normal for these values to be >0xFFFFe000. When they (randomly) hit 0xFFFFFFF0 exactly the idle check will incorrectly fail and suspend will hang. Actually, it is wrong when address reach to Hardware->lastWaitLink + 16, because the address shall be either Hardware->lastWaitLink(wait command) or Hardware->lastWaitLink + 8 (link command). Fix the end address offset with 8 or 16 (extra 8 bytes for L2 flush). Signed-off-by: Xianzhong <xianzhong.li@nxp.com> (cherry picked from commit 536d8f09d04460fe4912a2514e98beb31251ee3d)

2018-08-24MGS-3848-2 [#imx-854] fix events stuck issue when clock offXianzhong
When pm (SetPowerManagementState) is running power ON to SUSPEND_BROADCAST, it only checks wait-link FE, but not Async FE. Clock can be off when read AsyncFE Acknowledge register and other. pm thread: ... check commit atom ok >> check idle OK (former stopIsr before cl144673 is here) set GPU clock off ... isr: gcmkONERROR(ReadRegister(AQ_INTR_ACKNOWLEDGE_Address)); gckEVENT_Interrupt >>> here, at this point, all interrupt comes, check idle in >>> pm thread can pass. gcmkONERROR(ReadRegister(AQ_INTR_ACKNOWLEDGE_EX_Address)); gckFE_UpdateAvaiable -> ReadRegister(GCREG_FE_ASYNC_STATUS_Address) If gcmkONERROR(ReadRegister(AQ_INTR_ACKNOWLEDGE_EX_Address)) fail of clock off, then gckHARDWARE_Interrupt fails. In isrRoutine, it won't wake up threadRoutine. Then it's stuck! ReadRegister(GCREG_FE_ASYNC_STATUS_Address) failure can cause unexpected behavior, too. Former stopIsr (free_irq, before cl144673) can remove isr before GPU clock off. So the issue is hidden. To fix: 1. We should return success when either FE or AsyncFE reports correct interrupts, so that isr can wake up threadRoutine for either FE. That means, only need return ERROR when both FEs reports ERROR. 2. Add check for status of ReadRegister(GCREG_FE_ASYNC_STATUS_Address).
