Halt the emulater in case a fault happens. This simplifies debugging because you won't see unneccessary instructions which shouldn't be executed. Signed-off-by: Helge Deller <deller@gmx.de>
2022-05-26parisc: SEABIOS_HPPA_VERSION 6seabios-hppa-v6v6-testHelge Deller1-3/+12
Fixes the serial port emulation Qemu versions which request a SEABIOS_HPPA_VERSION < 6 have the bug that they use the DINO UART instead of the LASI UART as serial port #0. Staring with SEABIOS_HPPA_VERSION 6 the serial ports are now emulated as on physical hardware, with LASI UART being serial port #0. This patch adds a compat patch, which will use the DINO UART port for console I/O if it detects that qemu requests a SEABIOS_HPPA_VERSION < 6. Signed-off-by: Helge Deller <deller@gmx.de>

2022-05-26parisc: Provide serial port name based on given hpa addressHelge Deller1-1/+1
Prevent usage of the hardcoded PARISC_SERIAL_CONSOLE value and instead check the given hpa and provide the correct serial port name. Signed-off-by: Helge Deller <deller@gmx.de>
2022-05-26parisc: Use serial port addresses for console I/O from PAGE0Helge Deller1-2/+2
The structs mem_kbd and mem_cons holds the HPA of the serial ports used for console I/O, so use those instead of hardcoding to PARISC_SERIAL_CONSOLE. There is no functional change with this, but now it complies to how the values from PAGE0 should be used. Signed-off-by: Helge Deller <deller@gmx.de>
2022-05-26parisc: Switch serial ports 1 and 2Helge Deller1-2/+2
On real hardware, Linux detects the UART which is built-into LASI as serial port #1, and the UART which is built-into DINO as serial port #2. But to now qemu and SeaBIOS used the UART on DINO as serial port #1, which breaks qemu's possibility to use the "-serial" option to pass-through host serial ports to the guest. Fix this by swapping the addresses of PORT_SERIAL1 and PORT_SERIAL2. Signed-off-by: Helge Deller <deller@gmx.de>

2022-05-26parisc: Allow key Z as Y in boot menuHelge Deller1-3/+5
On german keyboards, the Z key is positioned at the same location as Y on english keyboards. German users may thus type Z instead of Y. So this patch allows Z as synonym for Y. Signed-off-by: Helge Deller <deller@gmx.de>
2022-05-16parisc: SEABIOS_HPPA_VERSION 5seabios-hppa-v5Helge Deller1-1/+1
New features and fixes: * Fixed SeaBIOS PS/2 keyboard support. This now allows to use the qemu "-boot menu=on" option to start the firmware boot selection menu and provide a working menu with keyboard on serial (qemu "-nographic" option) and PS/2 keyboard (qemu "-graphic" option) on graphical screen.
2022-05-14parisc: Add full PDC firmware boot menuHelge Deller4-36/+209
Finally add the real boot menu. If qemu is started with the "-boot menu=on" option, the PDC boot menu is shown and the user can then boot any of the available SCSI disc/CDs. Just type "BOOT" (to boot the default device), or "BOOT FWSCSI.4" (to boot SCSI device #4). Signed-off-by: Helge Deller <deller@gmx.de>
2022-05-14parisc/lasips2: Fix lasips2_kbd_in() to return early without inputHelge Deller1-1/+8
lasips2_kbd_in() is used to read input from an emulated PS/2 keyboard. Since there is no interrupt support durig PDC/IODC we need to poll the PS/2 status flags to see if a new key was pressed. In order to be able to poll regularily, exit the loop to read already pressed chars as soon as possible. This can be done by calling handle_16() with register ah = 0x11 to check if keys are queued up and exit if none are available. This patch fixes the problem that keys couldn't be read when using a graphical output (artist graphics). This patch fixes palo and other bootloaders to be able to use input from the emulated PS/2 keyboard. Signed-off-by: Helge Deller <deller@gmx.de>

Fix the PDC rendenzvous code to clear all pending external intrrupts before entering the waiting loop. Without clearing them before, the CPU was waken up immediately again. This fixes the CPU hotplug on Linux, which can be run with chcpu -d 2 # to disable CPU2 chcpu -e 2 # to wake up CPU2 Signed-off-by: Helge Deller <deller@gmx.de>

2022-02-02parisc: Add Linux TER16x32 font to STI firmwareHelge Deller4-3/+2084

2022-01-12parisc: Add opt/console fw_cfg option to select default consoleHelge Deller1-4/+24
By default the firmware will choose the (virtual) graphics card as firmware console if the graphics card is available. If not it defaults to serial console. In some configurations it's useful to select the serial console als default output device even if the graphics card is available. For that, this patch adds the opt/console fw_cfg qemu option. Qemu option usage to switch the firmare to use the serial or graphics default output: -fw_cfg opt/console,string=serial -fw_cfg opt/console,string=graphics Signed-off-by: Helge Deller <deller@gmx.de>

Move the HPA for MEMORY_HPA out of the address space of the 16th CPU, and fix the PDC_COPROC_CFG PDC function to report functional FPUs for all configured CPUs. The documentation specifies that cr10 can only report for 8 CPUs, but that seems outdated as both HP-UX 10 and HP-UX 11 accepts this change. Signed-off-by: Helge Deller <deller@gmx.de>

2022-01-06parisc: Add TOC button supportHelge Deller4-10/+279
Add support for an emulated TOC/NMI button. 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. This patch writes the CPU registers into PIM (processor internal memmory) for later analysis. It uses the CPU "shadow registers", the IAOQ-back and IASQ-back values are provided by qemu in r24/r25. This patch uses the new qemu aritificial opcode "getshadowregs" (0xfffdead2) which restores the original values of the shadow registers. 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.

2022-01-02parisc: Add opt/hostid fw_cfg option to change hostidHelge Deller1-3/+7
Allow the user to select another hostid value. In HP/UX the "uname -i" command shows the number, and in Linux it's visible in the /proc/cpuinfo output. The default hostid number is 2006243326, any other value can be selected with this qemu command line option: -fw_cfg opt/hostid,string=334455 Signed-off-by: Helge Deller <deller@gmx.de>
2021-09-24parisc: Increase SEABIOS_HPPA_VERSION to version 2seabios-hppa-v2parisc-qemu-6hppa-target-2Helge Deller1-1/+1
This version adds fixes which allow choosing the primary boot device. Either via qemu bootindex parameter, e.g.: -device scsi-hd,drive=drive1,bus=scsi0.0,channel=0,scsi-id=6,lun=0,bootindex=1 -drive file=image.img,if=none,id=drive1 or via qemu boot order option to select the SCSI ID, e.g.: -boot order=g-m: machine implementation dependent drives (SCSI ID) where "g" means SCSI ID 0, "h" is SCSI ID 1 and so on.

2021-09-24parisc: Fix boot priority and malloc initializationsHelge Deller1-2/+6
Make the malloc area initialization the first step after bootup. It's important, because the first mallocs otherwise ends up in lower memory area (PAGE0 from parisc) which will gets overwritten later. That change fixes the fw_cfg() interface as well. Before that change fw_cfg got initialized and zeroed-out shortly later in the boot process. And now the initialization of the boot structures succeeds too, so we can run boot_init() directly after setting up malloc and fw_cfg, and the bootindex parameter from qemu suddenly works out of the box.

2021-09-24boot: Fix qemu bootindex parameter on parisc architectureHelge Deller1-0/+4
On parisc qemu reports the main PCI bus as "/dino-pcihost" instead of "/pci@i0cf8". This is important when using the bootindex parameter for SCSI discs, because the seabios boot code uses this name as prefix when identifying and sorting the bootable discs.

2021-09-24boot: Allow boot order=g-m option to choose boot SCSI IDHelge Deller1-1/+10
