Check for pending OCC messages on HBRT start in OpenPOWER

2018-04-17T18:15:53+00:00

The OCC will set an interrupt for the Host to look for a pending message/action. If opal-prd is not running at the time that this interrupt happens, HTMGT will never see the message. Therefore we need to have HTMGT explicitly check for anything pending any time HBRT starts up.

Initialize FIRDATA section and ErrlManager just incase BMC resets

2018-03-07T17:54:24+00:00

PRD needs to read the PNOR to tell OCC where to write in the pnor. This will cache the PNOR section so PRD will not fail the read call. If an error is created with pnor inaccessible, errl manager could get stuck unless it was initialized first.

Initialize SBE message communication on HBRT start

2018-02-07T22:40:16+00:00

Need to clear first 2 bits in CFAM register 0x283B. This basically resets our SBE communication stream just incase HBRT restarts after processing SBE interrupt. Clearing these bits tells the sender to resend the command.

Convert cmpi to cmpwi to fix build for modern binutils

2017-06-26T14:05:11+00:00

From Linux 80f23935cadb ("powerpc: Convert cmp to cmpd in idle enter sequence"): PowerPC's "cmp" instruction has four operands. Normally people write "cmpw" or "cmpd" for the second cmp operand 0 or 1. But, frequently people forget, and write "cmp" with just three operands. With older binutils this is silently accepted as if this was "cmpw", while often "cmpd" is wanted. With newer binutils GAS will complain about this for 64-bit code. For 32-bit code it still silently assumes "cmpw" is what is meant. In this instance the code comes directly from ISA v2.07, including the cmp, but cmpd is correct. Backport to stable so that new toolchains can build old kernels. This is change is a noop with the existing toolchain. We change from implicitly generating the cmpwi to explicitly stating in for compatibility with newer toolchains. With gcc 4.9.3, binutils 2.25.2: $ cat asm-test.S .text .global test cmpi 0, 8, 1 $ powerpc64-linux-gcc -c asm-test.S $ objdump -d asm-test.o 0000000000000000 <.text>: 2c 08 00 01 cmpwi r8,1 Old compiler, updated instruction: $ cat asm-test.S .text .global test cmpwi 0, 8, 1 $ powerpc64-linux-gcc -c asm-test.S $ objdump -d asm-test.o 0000000000000000 <.text>: 2c 08 00 01 cmpwi r8,1 And then the new toolchain (gcc 6.3.0, binutils 2.28) with the updated asm: $ cat asm-test.S .text .global test cmpwi 0, 8, 1 $ powerpc64-linux-gnu-gcc -c asm-test.S $ objdump -d asm-test.o 0000000000000000 <.text>: 2c 08 00 01 cmpwi r8,1 Change-Id: If981e20a578ec98ede68a31eee2888c27d5c3d10 Signed-off-by: Joel Stanley Reviewed-on: http://ralgit01.raleigh.ibm.com/gerrit1/42259 Tested-by: Jenkins Server Tested-by: FSP CI Jenkins Reviewed-by: STEWART E.
