MFC: Add atomic_fetchadd(9) operation for types int and 32.

2005-10-06T18:12:06Z

Other small updates to atomic(9) include: - Note that arm and ppc don't provide 64-bit atomic ops. - Update sample code. Approved by: re (scottl)

MFC: Stop using the '+' constraint modifier with memory operands in

2005-09-26T19:54:19Z

inline assembly. We still use it for register operands in various places. Approved by: re (kensmith)

MFC: Convert the atomic pointer operations to operate on uintptr_t rather

than void *. Approved by: re (kensmith)

Some cleanups and tweaks to some of the atomic.h files in preparation for

2005-07-09T12:38:53Z

further changes and fixes in the future: - Use aliases via macros rather than duplicated inlines wherever possible. - Move all the aliases to the bottom of these files and the inline functions to the top. - Add various comments. - On alpha, drop atomic_{load_acq,store_rel}_{8,char,16,short}(). - On i386 and amd64, don't duplicate the extern declarations for functions in the two non-inline cases (KLD_MODULE and compiler doesn't do inlines), instead, consolidate those two cases. - Some whitespace fixes.

MFP4:

- Implement sampling modes and logging support in hwpmc(4). - Separate MI and MD parts of hwpmc(4) and allow sharing of PMC implementations across different architectures. Add support for P4 (EMT64) style PMCs to the amd64 code. - New pmcstat(8) options: -E (exit time counts) -W (counts every context switch), -R (print log file). - pmc(3) API changes, improve our ability to keep ABI compatibility in the future. Add more 'alias' names for commonly used events. - bug fixes & documentation.

Remove bus_{mem,p}io.h and related code for a micro-optimization on i386

and amd64. The optimization is a trivial on recent machines. Reviewed by: -arch (imp, marcel, dfr)

Change the spkr_set_pitch() function to a macro to fix low level profiling.

- Move timerreg.h to /include and split i8253 specific defines into

2005-05-14T09:10:02Z

i8253reg.h, and add some defines to control a speaker. - Move PPI related defines from i386/isa/spkr.c into ppireg.h and use them. - Move IO_{PPI,TIMER} defines into ppireg.h and timerreg.h respectively. - Use isa/isareg.h rather than /isa/isa.h. Tested on: i386, pc98

Add empty header (except of the multiple-inclusion protection) to

get hwpmc(4) to compile on this platform.

Break out the definition of bus_space_{tag,handle}_t and a few other types

2005-04-18T21:45:34Z

into _bus.h to help with name space polution from including all of bus.h. In a few days, I'll commit changes to the MI code to take advantage of thse sepration (after I've made sure that these changes don't break anything in the main tree, I've tested in my trees, but you never know...).
