Esteban wrote me over the weekend asking about raspi4 progress. I cleaned up my patches/notes to pass him. Other help is also welcomed :) I got scared trying to understand how to use the GIC, and wire the various IRQs.
Most important notes about testing are in patch #12: "Add the BCM2838 which uses a GICv2" Not much works yet, it only runs a bit until configuring the GIC. branch pushed at https://gitlab.com/philmd/qemu/commits/raspi4_wip Regards, Phil. based-on: 20190903120555.7551-1-phi...@redhat.com cutils: Move size_to_str() from "qemu-common.h" to "qemu/cutils.h" https://lists.gnu.org/archive/html/qemu-devel/2019-09/msg00229.html Philippe Mathieu-Daudé (14): hw/arm/raspi: Use the IEC binary prefix definitions hw/misc/bcm2835_property: Add FIXME comment for uninitialized memory hw/misc/bcm2835_property: Handle the 'domain state' property hw/arm/bcm2835_peripherals: Improve logging hw/arm/bcm2835_peripherals: Name various address spaces hw/arm/bcm2835: Rename some definitions hw/arm/bcm2835: Add various unimplemented peripherals hw/arm/bcm2836: Make the SoC code modular hw/arm/raspi: Make the board code modular hw/arm/raspi: Define various blocks base addresses hw/arm/bcm2835_peripherals: Map various BCM2838 blocks hw/arm/bcm2836: Add the BCM2838 which uses a GICv2 hw/arm/bcm2838: Map the PCIe memory space hw/arm/raspi: Add the Raspberry Pi 4B board hw/arm/bcm2835_peripherals.c | 49 ++++++++- hw/arm/bcm2836.c | 103 +++++++++++++++++-- hw/arm/raspi.c | 142 ++++++++++++++++++++++++--- hw/char/bcm2835_aux.c | 5 +- hw/display/bcm2835_fb.c | 2 +- hw/dma/bcm2835_dma.c | 10 +- hw/intc/bcm2836_control.c | 7 +- hw/misc/bcm2835_mbox.c | 9 +- hw/misc/bcm2835_property.c | 28 ++++-- include/hw/arm/bcm2835_peripherals.h | 18 ++++ include/hw/arm/bcm2836.h | 3 + include/hw/arm/raspi_platform.h | 79 ++++++++++++--- 12 files changed, 393 insertions(+), 62 deletions(-) -- 2.20.1
