The trie usage stats were currently being shared by all threads that were calling fib_table_lookup. As a result when multiple threads were performing lookups simultaneously the trie would begin to cache bounce between those threads. In order to prevent this I have updated the usage stats to use a set of percpu variables. By doing this we should be able to avoid the cache bouncing and still make use of these stats.

Richard Cochran says: ==================== Time Counter fixes and improvements Several PTP Hardware Clock (PHC) drivers implement the clock in software using the timecounter/cyclecounter code. This series adds one simple improvement and one more subtle fix to the shared timecounter facility. Credit for this series goes to Janusz Użycki, who pointed the issues out to me off list. Patch #1 simply move the timecounter code into its own file. When working on this series, it was really annoying to see half the kernel recompile after every tweak to the timecounter stuff. There is no reason to keep this together with the clocksource code. Patch #2 implements an improved adjtime() method, and patches 3-10 convert all of the drivers over to the new method. Patch #11 fixes a subtle but important issue with the timecounter WRT frequency adjustment. As it stands now, a timecounter based PHC will exhibit a variable frequency resolution (and variable time error) depending on how often the clock is read. In timecounter_read_delta(), the expression (delta * cc->mult) >> cc->shift; can lose resolution from the adjusted value of 'mult'. If the value of 'delta' is too small, then small changes in 'mult' have no effect. However, if the delta value is large enough, then small changes in 'mult' will have an effect. Reading the clock too often means smaller 'delta' values which in turn will spoil the fine adjustments made to 'mult'. Up until now, this effect did not show up in my testing. The following example explains why. The CPTS has an input clock of 250 MHz, and the clock source uses mult=0x80000000 and shift=29, making the ticks to nanoseconds conversion like this: ticks * 2^31 ------------ 2^29 Imagine what happens if the clock is read every 10 milliseconds. Ten milliseconds are about 2500000 ticks, which corresponds to about 21 bits. The product in the numerator has then 52 bits. After the shift operation, 23 bits are preserved. This results in a frequency adjustment resolution of about 0.1 ppm (not _too_ bad.) A frequency resolution of 1 ppm requires 20 bits. A frequency resolution of 1 ppb requires 30 bits. For the 250 MHz CPTS clock, reading every 4 seconds yields a 1 ppb resolution (which is the finest that our API allows). However, the error can be much higher if the clock is read too often or if time stamps occur close in time to read operations. In general it is really not acceptable to allow the rate of clock readings to influence the clock accuracy. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

The current timecounter implementation will drop a variable amount of resolution, depending on the magnitude of the time delta. In other words, reading the clock too often or too close to a time stamp conversion will introduce errors into the time values. This patch fixes the issue by introducing a fractional nanosecond field that accumulates the low order bits.

Some PTP Hardware Clock drivers use a struct timecounter to represent their clock. To adjust the time by a given offset, these drivers all perform a two step read/write of their timecounter. However, it is better and simpler just to adjust the offset in one step. This patch introduces a little routine to help drivers implement the adjtime method.
