* Make the wchar_t type machine dependent.Andrew Turner2012-06-2415-45/+40
| | | | | | | | | | | | | | | | | This is required for ARM EABI. Section 7.1.1 of the Procedure Call for the ARM Architecture (AAPCS) defines wchar_t as either an unsigned int or an unsigned short with the former preferred. Because of this requirement we need to move the definition of __wchar_t to a machine dependent header. It also cleans up the macros defining the limits of wchar_t by defining __WCHAR_MIN and __WCHAR_MAX in the same machine dependent header then using them to define WCHAR_MIN and WCHAR_MAX respectively.

* Introduce reserve_pv_entry() and use it in pmap_pv_demote_pde(). In orderAlan Cox2012-06-231-1/+83
| | | | | | | | | | | | to add PV list locking to pmap_pv_demote_pde(), it is necessary to change the way that pmap_pv_demote_pde() allocates PV entries. Specifically, once pmap_pv_demote_pde() begins modifying the PV lists, it can't allocate any new PV chunks, because that could require the PV list lock to be dropped. So, all necessary PV chunks must be allocated in advance. To my surprise, this new approach is a few percent faster than the old one. Notes: svn path=/head/; revision=237513

Establish the permanent mapping of the shared page into the kernel address space, avoiding the potential need to sleep waiting for allocation of sf buffer during vdso_timehands update. As a consequence, shared_page_write_start() and shared_page_write_end() functions are not needed anymore. Guess and memorize the pointers to native host and compat32 sysentvec during initialization, to avoid the need to get shared_page_alloc_sx lock during the update. In tc_fill_vdso_timehands(), do not loop waiting for timehands generation to stabilize, since vdso_timehands is written in the same interrupt context which wrote timehands.

* Change 'camcontrol defects' to first probe a drive to find out how muchKenneth D. Merry2012-06-223-7/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | defect information it has before grabbing the full defect list. This works around a bug with some Hitachi drives that generate data overrun errors when they are asked for more defect data than they have. The change is done in a spec-compliant way, so it should have no negative impact on drives that don't have this issue. This is based on work originally done at Sandvine. scsi_da.h: Add a define for the maximum amount of data that can be contained in a defect list. camcontrol.c: Update the readdefects() function to issue an initial command to determine the length of the defect list, and then use that length in the request for the full defect list. camcontrol.8: Add a note that some drives will report 0 defects available if you don't request either the PLIST or GLIST.

As a consequence it has been difficult to do an appropriate MFV and we have been bringing only partial updates. Here we update most of the files to at least match the version available in NetBSD's snapshot of 20091228. This version was chosen because it still doesn't include wide character support (UTF-8), which involves many changes and new files.

* Implement mechanism to export some kernel timekeeping data toKonstantin Belousov2012-06-2221-0/+636
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | usermode, using shared page. The structures and functions have vdso prefix, to indicate the intended location of the code in some future. The versioned per-algorithm data is exported in the format of struct vdso_timehands, which mostly repeats the content of in-kernel struct timehands. Usermode reading of the structure can be lockless. Compatibility export for 32bit processes on 64bit host is also provided. Kernel also provides usermode with indication about currently used timecounter, so that libc can fall back to syscall if configured timecounter is unknown to usermode code. The shared data updates are initiated both from the tc_windup(), where a fast task is queued to do the update, and from sysctl handlers which change timecounter. A manual override switch kern.timecounter.fast_gettime allows to turn off the mechanism. Only x86 architectures export the real algorithm data, and there, only for tsc timecounter. HPET counters page could be exported as well, but I prefer to not further glue the kernel and libc ABI there until proper vdso-based solution is developed. Minimal stubs neccessary for non-x86 architectures to still compile are provided. Discussed with: bde Reviewed by: jhb Tested by: flo MFC after: 1 month Notes: svn path=/head/; revision=237433
