parisc: Do not reprogram affinitiy on ASP chip

2025-11-25T14:23:02+00:00

The ASP chip is a very old variant of the GSP chip and is used e.g. in HP 730 workstations. When trying to reprogram the affinity it will crash with a HPMC as the relevant registers don't seem to be at the usual location. Let's avoid the crash by checking the sversion. Also note, that reprogramming isn't necessary either, as the HP730 is a just a single-CPU machine. Signed-off-by: Helge Deller Cc: stable@vger.kernel.org

parisc: lasi: Initialize LASI driver via arch_initcall()

2023-08-27T09:09:10+00:00

Move initialization code for LASI out of the GSC driver. Since ASP and WAX have been moved in previous commits, the GSC driver is now just a driver which provides library functions for LASI, ASP and WAX and as such doesn't need an own initialization function any longer. Signed-off-by: Helge Deller

parisc: gsc: Convert GSC bus driver to use arch_initcall()

This conversion includes LASI, ASP and WAX drivers for now. Signed-off-by: Helge Deller

parisc: Fix CPU affinity for Lasi, WAX and Dino chips

2022-03-29T19:37:12+00:00

Add the missing logic to allow Lasi, WAX and Dino to set the CPU affinity. This fixes IRQ migration to other CPUs when a CPU is shutdown which currently holds the IRQs for one of those chips. Signed-off-by: Helge Deller

[PARISC] Convert to new irq_chip functions

2011-02-10T16:22:14+00:00

Convert all the parisc driver interrupt handlers (dino, eisa, gsc, iosapic and superio) as well as the cpu interrupts. Prepare show_interrupts for GENERIC_HARDIRQS_NO_DEPRECATED and finally selects that Kconfig option [jejb: compile and testing fixes] Signed-off-by: Thomas Gleixner Signed-off-by: James Bottomley

parisc: convert the rest of the irq handlers to simple/percpu

2010-12-04T16:15:19+00:00

The generic conversion eliminates the spurious no_ack and no_end routines, converts all the cascaded handlers to handle_simple_irq() and makes iosapic use a modified handle_percpu_irq() to become the same as the CPU irq's. This isn't an essential change, but it eliminates the mask/unmask overhead of handle_level_irq(). Signed-off-by: James Bottomley Tested-by: Helge Deller Signed-off-by: Kyle McMartin
