2023-10-20hw/hppa: Provide RTC and DebugOutputPort on CPU #0Helge Deller1-1/+0
For SeaBIOS-hppa, the RTC and DebugOutputPort were in the I/O area of the LASI chip of the emulated B160L machine. Since we will add other machines without a LASI chip, move the emulated devices into the I/O area of CPU#0 instead. Signed-off-by: Helge Deller <deller@gmx.de>
2022-05-28hppa: Fix serial port assignments and pass-throughHelge Deller1-2/+2
This fixes the serial ports in the emulation to behave as on original hardware. On the real hardware, the LASI UART is serial port #0 and the DINO UART is serial port #1. This is fixed in SeaBIOS-hppa firmware v6, which is why at least this firmware version is required. The serial port addresses in hppa/hppa_hardware.h have to be swapped, and when creating the virtual serial ports the correct port addresses are used. This patch now for example allows to specify on the qemu command line: -serial mon:stdio -serial /dev/ttyS4 to use the emulated ttyS0 in the guest for console output, and pass ttyS4 from the host to ttyS1 in the guest.

2022-05-28hppa: Sync contents of hppa_hardware.h header file with SeaBIOS-hppaHelge Deller1-0/+6
The hppa_hardware.h header file holds many constants for addresses and offsets which are needed while building the firmware (SeaBIOS-hppa) and while setting up the virtual machine in QEMU. That's why this header file needs to be in sync between both source code repositories. This patch adds a comment mentioning this dependency at the top of this file and restores some DINO relevant offsets.

This is to allow us to decouple the DINO device from the board logic.

2022-02-02hw/hppa: Allow up to 16 emulated CPUsHelge Deller1-2/+3
This brings the hppa_hardware.h file in sync with the copy in the SeaBIOS-hppa sources. In order to support up to 16 CPUs, it's required to move the HPA for MEMORY_HPA out of the address space of the new 16th CPU. The new address of 0xfffff000 worked well for Linux and HP-UX, while other addresses close to the former 0xfffbf000 area are used by the architecture for local and global broadcasts. The PIM_STORAGE_SIZE constant is used in SeaBIOS sources and is relevant for the TOC/NMI feature.

2020-09-02hw/hppa: Tell SeaBIOS port address of fw_cfgHelge Deller1-1/+1
Change QEMU_FW_CFG_IO_BASE to shorter variant FW_CFG_IO_BASE and hand over the actual port address in %r19 to SeaBIOS. Signed-off-by: Helge Deller <deller@gmx.de> Reviewed-by: Richard Henderson <richard.henderson@linaro.org>
2020-09-02hw/hppa: Change fw_cfg port addressHelge Deller1-2/+1
Devices on hppa occupy at least 4k starting at the HPA, so MEMORY_HPA+4k is blocked (by Linux) for the memory module. I noticed this when testing the new Linux kernel patch to let the fw_cfg entries show up in Linux under /proc. The Linux kernel driver could not allocate the region for fw_cfg. This new base address seems to not conflict. Signed-off-by: Helge Deller <deller@gmx.de> Reviewed-by: Richard Henderson <richard.henderson@linaro.org>

2020-01-27hppa: Add emulation of Artist graphicsSven Schnelle1-0/+1
This adds emulation of Artist graphics good enough to get a text console on both Linux and HP-UX. The X11 server from HP-UX also works. Adjust boot-serial-test to disable graphics, so that SeaBIOS outputs to the serial port, as expected by the test.

2019-03-15Update seabios-hppa to latest upstreamHelge Deller1-2/+2
This patch fixes two issues in the hppa/parisc emulation: 1. The CPU HPA was wrong in the sense that we had negative module offsets in the firmware-internal module table (which we ignored up to now). Get it correct by changing the CPU HPA to 0xfffb0000 which is greater than the DINO_HPA of 0xfff80000. This change requires the seabios-firmware update. 2. Sven noticed that the FPU register cr10 is only able to reference up to 8 FPUs, so let's reduce the maximum amount of SMP CPUs too.
