2023-09-16esp-scsi: handle non-DMA SCSI commands with no data phaseMark Cave-Ayland1-1/+10
The existing esp-scsi state machine checks for the STAT_TC bit to exit state 1 but in the case where there is no data phase, a non-DMA command is executed which doesn't set STAT_TC. This only works because QEMU currently always sets STAT_TC just after issuing every SCSI command. Update the esp-scsi state machine so that in the case where there is no data phase, we immediately execute CMD_ICCS instead of waiting for STAT_TC to be set which will never happen with a non-DMA CMD_SELATN command.

2023-09-16esp-scsi: check for INTR_BS/INTR_FC instead of STAT_TC for command completionMark Cave-Ayland1-14/+22
The ESP SELATN command used to send SCSI commands from the ESP to the SCSI bus is not a DMA command and therefore does not affect the STAT_TC bit. The only reason this works at all is due to a bug in QEMU which (currently) always updates the STAT_TC bit in ESP_RSTAT regardless of the state of the ESP_CMD_DMA bit. According to the NCR datasheet [1] the INTR_BS/INTR_FC bits are set when the SELATN command has completed, so update the existing logic to check for these bits in ESP_RINTR instead. Note that the read of ESP_RINTR needs to be restricted to state == 0 as reading ESP_RINTR resets the ESP_RSTAT register which breaks the STAT_TC check when state == 1. This commit also includes an extra read of ESP_INTR to clear all the interrupt bits before submitting the SELATN command to ensure that we don't accidentally immediately progress to the data phase handling logic where ESP_RINTR bits have already been set by a previous ESP command.

2023-09-16esp-scsi: flush FIFO before sending SCSI commandMark Cave-Ayland1-0/+4
The ESP FIFO is used as a buffer for DMA requests and so isn't guaranteed to be empty in the case of SCSI errors or a mixed DMA/non-DMA request. Flush the FIFO before sending a SCSI command to guarantee that it is correctly positioned at the start of the FIFO.

2023-09-13parisc: Implement Block-TLB (BTLB) support for 32-bit CPUsHelge Deller1-20/+11
SeaBIOS has no information about the lower implementation details for Block-TLB (or generic TLB) support, so it simply hands over the parameters in the CPU registers provided by the operating system to the PDC_BLOCK_TLB PDC function to QEMU. Calling QEMU happens via a diagnostics instruction (diag 0x100) which QEMU will respond to. Older QEMU versions without the BTLB support will simply log that they ignored the diag instruction, and SeaBIOS will return PDC_BAD_OPTION for this PDC call in that case.

2023-06-20parisc: SEABIOS_HPPA_VERSION 7seabios-hppa-v7Helge Deller1-6/+27
Fixes boot of the Debian-12 installation CD-ROM The size of the ramdisc of Debian-12 is 17123328 bytes and occupies 8361 CD-ROM sectors (of 2048 bytes each). As such the palo bootloader tries to read 8361 sectors, which fails with DISK_RET_EBADTRACK error because the emulated LSI SCSI driver only supports (due to hardware limitation) reading 8192 sectors at once. Fix it in the SeaBIOS firmware by limiting the sectors which can be read at once to 8192-16 sectors. The palo bootloader will then simply do additional calls to read the remaining sectors. This firmware bug didn't show up with Debian-11 because that ramdisc was smaller and below the 8192 sector limit. 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: 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>

2022-05-14parisc/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>

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.

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.
