parisc: Add Page Deallocation Table (PDT) support

2017-05-12T07:14:15+00:00

The firmare in most parisc machines maintains a Page Deallocation Table (PDT)
which holds a list of physical memory addresses where hardware detected memory
errors (single bit and double bit errors).

This patch adds the missing PDC firmware calls and the logic to read the PDT
from firmware, report all current PDT entries and exclude the reported bad
memory from being used by Linux.

parisc: Enhance CPU detection code on PAT machines

2016-12-12T21:28:09+00:00

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

parisc: Use kmalloc_array() in add_system_map_addresses()

2016-09-20T16:02:56+00:00

* A multiplication for the size determination of a memory allocation
  indicated that an array data structure should be processed.
  Thus use the corresponding function "kmalloc_array".

  This issue was detected by using the Coccinelle software.

* Replace the specification of a data type by a pointer dereference
  to make the corresponding size determination a bit safer according to
  the Linux coding style convention.

parisc: Fix interrupt routing for C8000 serial ports

2013-07-31T21:42:32+00:00

We can't use dev->mod_index for selecting the interrupt routing entry,
because it's not an index into interrupt routing table. It will be even
wrong on a machine with 2 CPUs (4 cores). But all needed information is
contained in the PAT entries for the serial ports. mod[0] contains the
iosapic address and mod_info has some indications for the interrupt
input (at least it looks like it). This patch implements the searching
for the right iosapic and uses this interrupt input information.

parisc: fix possible memory leak in pat_query_module()

2013-02-20T21:47:11+00:00

pa_pdc_cell has been allocated in this function and so should be
freed before leaving from the error handling cases.

spatch with a semantic match is used to found this problem.

The pa_pdc_cell struct can be kmalloc'd, so do that
instead.
