sysdev: Pass the attribute to the low level sysdev show/store function

2008-07-22T04:55:02Z

This allow to dynamically generate attributes and share show/store functions between attributes. Right now most attributes are generated by special macros and lots of duplicated code. With the attribute passed it's instead possible to attach some data to the attribute and then use that in shared low level functions to do different things. I need this for the dynamically generated bank attributes in the x86 machine check code, but it'll allow some further cleanups. I converted all users in tree to the new show/store prototype. It's a single huge patch to avoid unbisectable sections. Runtime tested: x86-32, x86-64 Compiled only: ia64, powerpc Not compile tested/only grep converted: sh, arm, avr32 Signed-off-by: Andi Kleen Signed-off-by: Greg Kroah-Hartman

[SPARC64]: Add NUMA support.

2008-04-24T06:32:17Z

Currently there is only code to parse NUMA attributes on sun4v/niagara systems, but later on we will add such parsing for older systems. Signed-off-by: David S. Miller

[SPARC64]: More sensible udelay implementation.

2007-07-16T11:05:02Z

Take a page from the powerpc folks and just calculate the delay factor directly. Since frequency scaling chips use a system-tick register, the value is going to be the same system-wide. Signed-off-by: David S. Miller

[SPARC64]: Provide mmu statistics via sysfs.

2007-06-05T04:49:57Z

If the system supports hypervisor based statistics, allow them to be fetched, enabled, and disabled via sysfs. Enable and disable via the boolean: /sys/devices/systems/cpu/cpuN/mmustat_enable Statistic values are provided under: /sys/devices/systems/cpu/cpuN/mmu_status/ Signed-off-by: David S. Miller

[SPARC64]: Export basic cpu properties via sysfs.

2007-06-05T04:49:51Z

Cache sizes, udelay_val, and clock_tick. Signed-off-by: David S. Miller

[SPARC64]: Move topology init code into new file, sysfs.c

2007-06-05T04:49:50Z

Also, use per-cpu data for struct cpu. Calling kmalloc for each cpu in topology_init() is just plain clumsy. Signed-off-by: David S. Miller
