parisc: Show machine product number during boot

2019-02-21T19:37:13Z

Ask PDC firmware during boot for the original and current product number as well as the serial number and show it (if available). Signed-off-by: Helge Deller

parisc: Add CPU topology support

2017-11-17T14:27:22Z

Add topology support, including multi-core scheduler support on PA8800/PA8900 CPUs and enhanced output in /proc/cpuinfo, e.g. lscpu now reports on a single-socket, dual-core machine: Architecture: parisc64 CPU(s): 2 On-line CPU(s) list: 0,1 Thread(s) per core: 1 Core(s) per socket: 2 Socket(s): 1 CPU family: PA-RISC 2.0 Model name: PA8800 (Mako) Signed-off-by: Helge Deller

parisc/random: Add machine specific randomness

2017-08-22T14:34:34Z

Add some machine-specific information like values of cr16 cycle counter, machine-specific software ID and machine model to the random generator. Signed-off-by: Helge Deller

parisc: Enhance detection of synchronous cr16 clocksources

2017-05-10T15:46:14Z

The cr16 clocks of the physical PARISC CPUs are usually nonsynchronous. Nevertheless, it seems that each CPU socket (which holds two cores) of PA8800 and PA8900 CPUs (e.g. in a C8000 workstation) is fed by the same clock source, which makes the cr16 clocks of each CPU socket syncronous. Let's try to detect such situations and mark the cr16 clocksource stable on single-socket and single-core machines. Signed-off-by: Helge Deller

parisc: Optimize timer interrupt function

2016-12-20T20:39:40Z

Restructure the timer interrupt function to better cope with missed timer irqs. Optimize the calculation when the next interrupt should happen and skip irqs if they would happen too shortly after exit of the irq function. The update_process_times() call is done anyway at every timer irq, so we can safely drop the prof_counter and prof_multiplier variables from the per_cpu structure. Signed-off-by: Helge Deller

parisc: Enhance CPU detection code on PAT machines

2016-12-12T21:28:09Z

This patch fixes the debug code which runs during the inventory scan on machines with PAT firmware. Additionally print out the relationship between the detected logical CPU number and it's physical location and physical cpu number. This leads to information which can be used to feed numa-structures in the kernel in later patches. An example output is from my single-CPU (2 cores) C8000 machine is: Logical CPU #0 is physical cpu #0 at 0xffff0000ffff15, hpa 0xfffffffffe780000 Logical CPU #1 is physical cpu #1 at 0xffff0000ffff15, hpa 0xfffffffffe781000 Signed-off-by: Helge Deller

parisc: Fix automatic selection of cr16 clocksource

2016-08-20T11:33:51Z

Commit 54b66800907 (parisc: Add native high-resolution sched_clock() implementation) added support to use the CPU-internal cr16 counters as reliable clocksource with the help of HAVE_UNSTABLE_SCHED_CLOCK. Sadly the commit missed to remove the hack which prevented cr16 to become the default clocksource even on SMP systems. Signed-off-by: Helge Deller Cc: stable@vger.kernel.org # 4.7+
