2023-06-26target/hppa: Provide qemu version via fw_cfg to firmwareHelge Deller
Give current QEMU version string to SeaBIOS-hppa via fw_cfg interface so that the firmware can show the QEMU version in the boot menu info.

2023-06-26target/hppa: Fix OS reboot issuesHelge Deller
When the OS triggers a reboot, the reset helper function sends a qemu_system_reset_request(SHUTDOWN_CAUSE_GUEST_RESET) together with an EXCP_HLT exception to halt the CPUs. So, at reboot when initializing the CPUs again, make sure to set all instruction pointers to the firmware entry point, disable any interrupts, disable data and instruction translations, enable PSW_Q bit and tell qemu to unhalt (halted=0) the CPUs again. This fixes the various reboot issues which were seen when rebooting a Linux VM, including the case where even the monarch CPU has been virtually halted from the OS (e.g. via "chcpu -d 0" inside the Linux VM).

2022-05-28hppa: Fix serial port assignments and pass-throughHelge Deller
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.

2022-05-09Warn user if the vga flag is passed but no vga device is createdGautam Agrawal
A global boolean variable "vga_interface_created"(declared in softmmu/globals.c) has been used to track the creation of vga interface. If the vga flag is passed in the command line "default_vga"(declared in softmmu/vl.c) variable is set to 0. To warn user, the condition checks if vga_interface_created is false and default_vga is equal to 0. If "-vga none" is passed, this patch will not warn the user regarding the creation of VGA device. The warning "A -vga option was passed but this machine type does not use that option; no VGA device has been created" is logged if vga flag is passed but no vga device is created. This patch has been tested for x86_64, i386, sparc, sparc64 and arm boards.

2022-02-02hppa: Add support for an emulated TOC/NMI button.Helge Deller
Almost all PA-RISC machines have either a button that is labeled with 'TOC' or a BMC/GSP function to trigger a TOC. TOC is a non-maskable interrupt that is sent to the processor. This can be used for diagnostic purposes like obtaining a stack trace/register dump or to enter KDB/KGDB in Linux. This patch adds support for such an emulated TOC button. It wires up the qemu monitor "nmi" command to trigger a TOC. For that it provides the hppa_nmi function which is assigned to the nmi_monitor_handler function pointer. When called it raises the EXCP_TOC hardware interrupt in the hppa_cpu_do_interrupt() function. The interrupt function then calls the architecturally defined TOC function in SeaBIOS-hppa firmware (at fixed address 0xf0000000). According to the PA-RISC PDC specification, the SeaBIOS firmware then writes the CPU registers into PIM (processor internal memmory) for later analysis. In order to write all registers it needs to know the contents of the CPU "shadow registers" and the IASQ- and IAOQ-back values. The IAOQ/IASQ values are provided by qemu in shadow registers when entering the SeaBIOS TOC function. This patch adds a new aritificial opcode "getshadowregs" (0xfffdead2) which restores the original values of the shadow registers. With this opcode SeaBIOS can store those registers as well into PIM before calling an OS-provided TOC handler. To trigger a TOC, switch to the qemu monitor with Ctrl-A C, and type in the command "nmi". After the TOC started the OS-debugger, exit the qemu monitor with Ctrl-A C.

2020-09-02hw/hppa: Make number of TLB and BTLB entries configurableHelge Deller
Until now the TLB size was fixed at 256 entries. To allow operating systems to utilize more TLB entries in the future, we need to tell firmware how many TLB entries we actually support in the emulation. Firmware then reports this to the operating system via the PDC_CACHE_INFO call. This patch simply does the preparation to allow more TLB entries. Signed-off-by: Helge Deller <deller@gmx.de>
2020-08-04hw/hppa: Implement proper SeaBIOS version checkHelge Deller
It's important that the SeaBIOS hppa firmware is at least at a minimal level to ensure proper interaction between qemu and firmware. Implement a proper firmware version check by telling SeaBIOS via the fw_cfg interface which minimal SeaBIOS version is required by this running qemu instance. If the firmware detects that it's too old, it will stop. Signed-off-by: Helge Deller <deller@gmx.de>
