Dear J. William Campbell, All

Lets just keep the current functions udelay(us) and u32 get_timer(), the latter maybe without parameter. Remove all *masked() and *reset() functions
This is happening and has Wolfgang's 100% support. Patches are done, just need to be rebased and resent
and lets change the timeout values used in code that also NIOS uses to be 20ms more than the hardware requires. It does not really matter if a *timeout* of 20ms is blown up to 40ms.
Can't do that - That would mean winding out common code (CFI, Network, Serial, FPGA etc, etc) timeouts to global worst-case scenario unless you want to add a #define and start littering the code with macro's - Urgh!
Hi All, Yes, this is true. However, the time_elapsed_since routine can do this dynamically (i.e. add twice the timer resolution) . I think you had another function name (at_least) involved, but you can define time_elapsed_since as always compensating for the resolution. That will fix any resolution questions in a processor-specific way. It is either that or the ifdefs. One way or another, the resolution must be addressed. Up to now, the implicit resolution has been 1 ms, but we now know that is not general enough.
