2023-11-11parisc: Fix powerbutton on 64-bit kernelHelge Deller1-2/+13
As long as this is a 32-bit PDC, we can't access a powerbutton in the firmware area when running on a 64-bit CPU. Report that non-supportability when asked by PDC_SOFT_POWER by a 64-bit kernel. Qemu may want to use some address in page zero instead. Signed-off-by: Helge Deller <deller@gmx.de>

2023-10-31parisc/sti: Fix STI crash with fonts with 64-bit Linux kernelHelge Deller1-0/+45
Just swapping font "next-font" pointers breaks the sti driver on older 64-bit Linux kernels which take the "next_font" pointer as unsigned int (instead of signed int) and thus calculates a wrong font start address. Avoid the crash by sorting the fonts in the STI ROM before the OS starts. A Linux kernel patch to avoid the crash was added in kernel 6.7. Signed-off-by: Helge Deller <deller@gmx.de>

2023-10-31parisc: Don't enable PSW.W at pdc exitHelge Deller1-2/+2
This fixes ODE for C3700, which aparently tried to run with PSW.W=1 and failed. Signed-off-by: Helge Deller <deller@gmx.de>
2023-10-31parisc: Lock 64-bit PDC calls until PDC_MODEL/PDC_MODEL_CAPABILITIES callHelge Deller1-2/+16
The OS needs to "unlock" the 64-bit functions. This fixes the ODE tool to detect the mapper instead of mapper2 tool. Signed-off-by: Helge Deller <deller@gmx.de>

2023-10-31parisc: Provide MEM_PDC_ENTRY as PDC entry point on SMP rendezvousHelge Deller3-5/+6
Hand over the architected MEM_PDC_ENTRY address (0x4800) instead of the native address of pdc_entry() when providing the PDC entry point in the SMP rendezvous function. This fixes the 64-bit SMP boot, since it avoids the ldil instruction which trashes he upper 32-bits. Secondly, the linux kernel checks the provided value against the PAGE0->mem_pdc value and complains if the differ. Signed-off-by: Helge Deller <deller@gmx.de>
2023-10-31parisc: Introduce new sw_id for the machinesHelge Deller3-9/+11
2004000160 for the B160L and 2004003700 for the C3700. Note the decimal numbers after the "2004" which reflects the emulated machine. Signed-off-by: Helge Deller <deller@gmx.de>

2023-10-31parisc: Save and restore current PSW_W across PDC callHelge Deller2-5/+19

2023-10-31parisc: Fully implement PDC_PSW for 64-bit CPUsHelge Deller2-4/+18
PDC_PSW tells the hardware how the default PSW is implemented. The w field indicates the default width of the processor. The w field also determines whether the External Interrupt Request (EIR) register is treated as a right-justified 32-bit register or a full 64-bit register. The e field indicates the default endianness of the processor. Both bits determine how the PSW W-bit and E-bit will be set on an interruption. Signed-off-by: Helge Deller <deller@gmx.de>
2023-10-31parisc: Fix mfctl,w instruction and thus 64-bit detectionHelge Deller1-2/+3
Use the wide version of mfctl to read the %sar register. Only the w-version is able to detect if we run on a 64-bit CPU. Signed-off-by: Helge Deller <deller@gmx.de>
