* [PATCH] arm: rename CLOCK_TICK_RATE to ARM_TICK_RATE [not found] <20090511222702.352192505@arndb.de> @ 2009-05-11 22:43 ` Arnd Bergmann 2009-05-11 23:11 ` [PATCH v2] " Arnd Bergmann 2009-05-13 17:11 ` [PATCH] " Arnd Bergmann 2009-05-11 22:55 ` [PATCH] move PIT_TICK_RATE to linux/timex.h Arnd Bergmann [not found] ` <200905121104.31275.arnd@arndb.de> 2 siblings, 2 replies; 8+ messages in thread From: Arnd Bergmann @ 2009-05-11 22:43 UTC (permalink / raw) To: Russell King, linux-kernel, linux-arch; +Cc: Alan Cox Most of the users of CLOCK_TICK_RATE in the kernel outside of ARM assume that it refers to the i8253 base frequency of 1.193182 Mhz, while in ARM it actually is the clock frequency of the timer. By renaming it to ARM_TICK_RATE for all arm specific device drivers, we can hopefully reduce the amount of confusion slightly.

By renaming it to ARM_TICK_RATE for all arm specific device drivers, we can hopefully reduce the amount of confusion slightly.

I did not check if the object file changes, just checked that the macro is not used in assembly code, which would break. Note that for Alpha, the actual value changed from 1193182UL to 1193180UL. This is unlikely to make a difference, and probably can only improve accuracy. There was a discussion on the correct value of CLOCK_TICK_RATE a few years ago, after which every existing instance was getting changed to 1193182. According to the specification, it should be 1193181.818181... Arnd <>< ^ permalink raw reply [flat|nested] 8+ messages in thread

Yes, but that would not help my intention of making the file more generic. The x86 code was copied into a number of architectures, and at least arm, m32r, parisc, sh and xtensa have big-endian configurations where the implementation is wrong. I only realized that while writing this email though and I guess I need to fix those as well now ;-) Arnd <>< ^ permalink raw reply [flat|nested] 8+ messages in thread
