Validate OMI INBAND BAR offset attributes against calculated values

2019-04-18T15:38:28+00:00

While setting up the virtual memory mapped IO to the OCMB chips we make some assumptions that the OCMB MMIO spaces will be contiguous. The p9a_omi_setup_bars HWP uses OMI_INBAND_BAR_BASE_ADDR_OFFSET to set the scom registers that determine the physical offset mapped to the IO. When setting up the Virtual addresses hostboot uses to represent the physical mmio address, we must validate that the attribute matches with what we calculated. While doing this we found that the virtual address attribute was being calculated incorrectly. It was not localizing the OCMB position relative to the MC which is required when calculating the offset into the MC bar.

Use the effective chip and group ids to calc mmio addr

2018-05-07T13:52:34+00:00

-A testcase was executed which garded out all the MBA's in the system, the expectation was that hostboot would attempt to configure enough hardware in the system to successfully ipl. However instead of IPLing multiple checkstops and various error logs were observed. -The testcase to gard all the mba's and then ipl the system resulted in there being no useable memory available for the master proc (proc0). In this case there is code which will swap the memory map around such that the sytem can still IPL. One of the requirements to enable the ability to swap the memory map around is to use the effective chip and group ids for calculating the memory ranges. -When setting the inband scom address for the DMI targets the existing calulation is using the default fabric chip group ids, this commit will change the calulation to use the "effective" chip and group ids when calculating the inband scom mmio range.

Ensure AbaPtr is not used in runtime code

2017-10-20T02:17:12+00:00

The AbaPtr makes assumptions that we have pointer values that are only 32-bits long. In our runtime (HBRT) environment that assumption is not true so we need to make sure none of the code that runs there is trying to use the AbaPtr code.
