linux.git/arch/parisc/kernel, branch v2.6.37 Linux kernel source tree parisc: convert the rest of the irq handlers to simple/percpu 2010-12-04T16:15:19+00:00 James Bottomley James.Bottomley@HansenPartnership.com 2010-12-03T02:01:05+00:00 51890613f2bfa70453a5cc22c91c63946dd311cd 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().

parisc: fix dino/gsc interrupts 2010-12-04T16:14:32+00:00 James Bottomley James.Bottomley@HansenPartnership.com 2010-12-02T23:36:47+00:00 d16cd297d288e48482c3c261db434a2e13bd9f20 The essential problem we're currently having is that dino (and gsc) is a cascaded CPU interrupt. Under the old __do_IRQ() handler, our CPU interrupts basically did an ack followed by an end. In the new scheme, we replaced them with level handlers which do a mask, an ack and then an unmask (but no end). Instead, with the renaming of end to eoi, we actually want to call the percpu flow handlers, because they actually have all the characteristics we want. This patch does the conversion and gets my C360 booting again. Signed-off-by: James Bottomley <James.Bottomley@suse.de> Signed-off-by: Kyle McMartin <kyle@mcmartin.ca>

It allows the use of ports not supported by linux as a console (e.g. serial port on C8000.) The tty driver will not register the ttyB device if PDC console driver has been unregistered. This happens when the early printk console is disabled as it has not been selected as the primary console.
