[PATCH] ppc64: Fix typo in time calculations

2005-10-21T19:17:43+00:00

This fixes a typo in the div128_by_32 function used in the timekeeping
calculations on ppc64.  If you look at the code it's quite obvious
that we need (rb + c) rather than (rb + b).  The "b" is clearly just a
typo.

[PATCH] NTP: ntp-helper functions

2005-09-07T23:57:34+00:00

This patch cleans up a commonly repeated set of changes to the NTP state
variables by adding two helper inline functions:

ntp_clear(): Clears the ntp state variables

ntp_synced(): Returns 1 if the system is synced with a time server.

This was compile tested for alpha, arm, i386, x86-64, ppc64, s390, sparc,
sparc64.

[PATCH] ppc64: make firmware_has_feature() stronger

2005-08-29T00:53:35+00:00

Make firmware_has_feature() evaluate at compile time for the non pSeries
case and tidy up code where possible.

[PATCH] ppc64: create firmware_has_feature()

2005-08-29T00:53:35+00:00

Create the firmware_has_feature() inline and move the firmware feature
stuff into its own header file.

[PATCH] ppc64: remove firmware features from cpu_spec

2005-08-29T00:53:34+00:00

The firmware_features field of struct cpu_spec should really be a separate
variable as the firmware features do not depend on the chip and the
bitmask is constructed independently.  By removing it, we save 112 bytes
from the cpu_specs array and we access the bitmask directly instead of via
the cur_cpu_spec pointer.

[PATCH] ppc64: Don't count number of events processed for caller

2005-06-30T05:15:53+00:00

Currently we count the number of lpevents processed in 3 seperate places.

One of these counters is never read, so just remove it. This means
hvlpevent_queue_process() no longer needs to return the number of events
processed.

[PATCH] ppc64: Rename ItLpQueue_* functions to hvlpevent_queue_*

2005-06-30T05:15:42+00:00

Now that we've renamed the xItLpQueue structure, rename the functions that
operate on it also.

[PATCH] ppc64: Don't pass the pointers to xItLpQueue around

2005-06-30T05:07:57+00:00

Because there's only one ItLpQueue and we know where it is, ie. xItLpQueue,
there's no point passing pointers to it it around all over the place.

[PATCH] ppc64: Remove lpqueue pointer from the paca on iSeries

2005-06-30T05:07:09+00:00

The iSeries code keeps a pointer to the ItLpQueue in its paca struct. But
all these pointers end up pointing to the one place, ie. xItLpQueue.

So remove the pointer from the paca struct and just refer to xItLpQueue
directly where needed.

The only complication is that the spread_lpevents logic was implemented by
having a NULL lpqueue pointer in the paca on CPUs that weren't supposed to
process events. Instead we just compare the spread_lpevents value to the
processor id to get the same behaviour.
