[PATCHv9 0/3] arm-virt: add secure pl061 for reset/power down

by Maxim Uvarov

v9: - cosmetic changes (move if from patch2 to patch3, rename function name and define). v8: - use gpio 0 and 1, align dtb with kernel gpio-restart, gpio-poweroff, change define names, trigger on upper front. (Peter Maydell). v7: - same as v6, but resplit patches: patch 2 no function changes and refactor gpio setup for virt platfrom and patch 3 adds secure gpio. v6: - 64k align gpio memory region (Andrew Jones) - adjusted memory region to map this address in the corresponding atf patch v5: - removed vms flag, added fdt (Andrew Jones) - added patch3 to combine secure and non secure pl061. It has to be more easy to review if this changes are in the separate patch. v4: rework patches accodring to Peter Maydells comments: - split patches on gpio-pwr driver and arm-virt integration. - start secure gpio only from virt-6.0. - rework qemu interface for gpio-pwr to use 2 named gpio. - put secure gpio to secure name space. v3: added missed include qemu/log.h for qemu_log(.. v2: replace printf with qemu_log (Philippe Mathieu-Daudé) This patch works together with ATF patch: https://github.com/muvarov/arm-trusted-firmware/commit/886965bddb0624bdf851… Maxim Uvarov (3): hw: gpio: implement gpio-pwr driver for qemu reset/poweroff arm-virt: refactor gpios creation arm-virt: add secure pl061 for reset/power down hw/arm/Kconfig | 1 + hw/arm/virt.c | 111 ++++++++++++++++++++++++++++++++++-------- hw/gpio/Kconfig | 3 ++ hw/gpio/gpio_pwr.c | 70 ++++++++++++++++++++++++++ hw/gpio/meson.build | 1 + include/hw/arm/virt.h | 2 + 6 files changed, 167 insertions(+), 21 deletions(-) create mode 100644 hw/gpio/gpio_pwr.c -- 2.17.1

Gather GIC changes required for safety critical machines

by Manish Pandey2

Hi, GIC600-AE is variant of GIC for safety critical machines, though its TRM is publicly available from quite some time but currently we do not have support in TF-A. Purpose of this email is to kick start discussions around various possible GIC requirements as far as safety critical machines are concerned. We have created following list of requirements based on inputs we got so far, changes are either adding new AE features or enhancements to existing drivers. GIC-600AE feature requirement: - Inject and detect RAS errors using Fault management unit(FMU) - Validating feature parity with GIC600 - Running GIC IP in Dual core Lock-step(DCLS) mode. GIC/RAS driver enhancements: - Read trace and PMU records - Keep RAS error records alive across a reset - Disable GICR frames of fused-off cores - Support for message signalled interrupts - Saving/Restoring additional GIC registers during PM events Feel free to add any additional requirements. If there is enough community interest during the next Tech-forum meeting(28th Jan) we would like to go through these requirements in more detail. Thanks Manish
