parisc: Fix return code of pdc_iodc_print()

2023-01-09T08:51:56Z

There is an off-by-one if the printed string includes a new-line char. Cc: stable@vger.kernel.org Signed-off-by: Helge Deller

parisc: Show MPE/iX model string at bootup

2022-12-19T15:08:52Z

Some (mostly 64-bit machines) machines allow to run MPE/iX and report the MPE model string via firmware call. Enhance the pdc_model_sysmodel() function to report that model string. Note that some 32-bit machines like the B160L wrongly report success for the firmware call, so include a check to prevent showing wrong info. Signed-off-by: Helge Deller

parisc: Move pdc_result struct to firmware.c

parisc: Fix locking in pdc_iodc_print() firmware call

2022-12-18T21:18:49Z

Utilize pdc_lock spinlock to protect parallel modifications of the iodc_dbuf[] buffer, check length to prevent buffer overflow of iodc_dbuf[], drop the iodc_retbuf[] buffer and fix some wrong indentings. Signed-off-by: Helge Deller Cc: # 6.0+

parisc: Add PDC locking functions for rendezvous code

2022-03-29T19:37:12Z

Add pdc_cpu_rendezvous_lock() and pdc_cpu_rendezvous_unlock() to lock PDC while CPU is transitioning into rendezvous state. This is needed, because the transition phase may take up to 8 seconds. Add pdc_pat_get_PDC_entrypoint() to get PDC entry point for current CPU. Signed-off-by: Helge Deller

parisc: Ensure set_firmware_width() is called only once

2022-03-29T19:37:12Z

Call set_firmware_width() only once at runtime. This prevents that hotplugged CPUs will get stuck in spinlocks later on. Signed-off-by: Helge Deller

parisc/firmware: add functions to retrieve TOC data

2021-11-01T06:35:59Z

Add functions to retrieve TOC data from firmware both for 1.1 and 2.0 PDC. Signed-off-by: Sven Schnelle Signed-off-by: Helge Deller

isystem: ship and use stdarg.h

2021-08-19T00:02:55Z

Ship minimal stdarg.h (1 type, 4 macros) as . stdarg.h is the only userspace header commonly used in the kernel.

parisc: firmware: Update references to parisc website

2020-06-01T21:02:11Z

The PA-RISC Linux project web page is now hosted at https://parisc.wiki.kernel.org Signed-off-by: Helge Deller

parisc: add __pdc_cpu_rendezvous()

2019-09-08T13:19:58Z

When stopping SMP cpus send them into rendezvous, so we can start them again later (when kexec'ing a new kernel). Signed-off-by: Sven Schnelle Signed-off-by: Helge Deller
