It replaces +:ref:`skiboot-6.0.16` as the current stable release in the 6.0.x series. + +It is recommended that 6.0.17 be used instead of any previous 6.0.x version +due to the bug fixes it contains. + +Bug fixes included in this release are: + +- core/opal: Print PIR value in exit path, which is useful for debugging. +- core/ipmi: Improve error message +- hdata: Fix dtc warnings + + Fix dtc warnings related to mcbist node :: + + Warning (reg_format): "reg" property in /xscom@623fc00000000/mcbist@1 has invalid length (4 bytes) (#address-cells == 1, #size-cells == 1) + Warning (reg_format): "reg" property in /xscom@623fc00000000/mcbist@2 has invalid length (4 bytes) (#address-cells == 1, #size-cells == 1) + Warning (reg_format): "reg" property in /xscom@603fc00000000/mcbist@1 has invalid length (4 bytes) (#address-cells == 1, #size-cells == 1) + Warning (reg_format): "reg" property in /xscom@603fc00000000/mcbist@2 has invalid length (4 bytes) (#address-cells == 1, #size-cells == 1) + + Ideally we should add proper xscom range here... but we are not getting that + information in HDAT today. Lets fix warning until we get proper data in HDAT. +- hdata/test: workaround dtc bugs + + In dtc v1.4.5 to at least v1.4.7 there have been a few bugs introduced + that change the layout of what's produced in the dts. In order to be + immune from them, we should use the (provided) dtdiff utility, but we + also need to run the dts we're diffing against through a dtb cycle in + order to ensure we get the same format as what the hdat_to_dt to dts + conversion will. + + This fixes a bunch of unit test failures on the version of dtc shipped + with recent Linux distros such as Fedora 29. +- firmware-versions: Add test case for parsing VERSION + + Also make it possible to use with afl-lop/afl-fuzz just to help make + *sure* we're all good. + + Additionally, if we hit a entry in VERSION that is larger than our + buffer size, we skip over it gracefully rather than overwriting the + stack. This is only a problem if VERSION isn't trusted, which as of + 4b8cc05a94513816d43fb8bd6178896b430af08f it is verified as part of + Secure Boot. +- core/cpu: HID update race + + If the per-core HID register is updated concurrently by multiple + threads, updates can get lost. This has been observed during fast + reboot where the HILE bit does not get cleared on all cores, which + can cause machine check exception interrupts to crash. + + Fix this by only updating HID on thread0. +- cpufeatures: Always advertise POWER8NVL as DD2 + + Despite the major version of PVR being 1 (0x004c0100) for POWER8NVL, + these chips are functionally equalent to P8/P8E DD2 levels. + + This advertises POWER8NVL as DD2. As the result, skiboot adds + ibm,powerpc-cpu-features/processor-control-facility for such CPUs and + the linux kernel can use hypervisor doorbell messages to wake secondary + threads; otherwise "KVM: CPU %d seems to be stuck" would appear because + of missing LPCR_PECEDH. -- cgit v1.1
