* Style fixes.Alexander Kabaev2003-05-041-9/+12
| | | | | | | | | | | | Remove DBL_DIG, DBL_MIN, DBL_MAX and their FLT_ counterparts, they were marked for deprecation ever since SUSv1 at least. Only define ULLONG_MIN/MAX and LLONG_MAX if long long type is supported. Restore a lost comment in MI _limits.h file and remove it from sys/limits.h where it does not belong.

* Fix the osf1 abi module on SMP systems by making the size ofAndrew Gallatin2003-03-292-2/+3
| | | | | | | | | | | | | | | | | | | a struct pmap be the same on both SMP and UP kernels. It turns out that the size of a struct pmap is much larger on alpha SMP systems due to the number of pm_asn's being dependant on MAX_CPU. Since modules are supposed to be SMP agnostic, this has the affect of moving around the "interesting bits" of the vmspace (daddr, dsize) that the osf1 module wants to frob. So the module ends up scribbling in a pmap struct, and the user either sees a panic, or an application failure. While here, I've also shrunk MAXCPU to 8 now that it affects the size of pmap structs on UP systesm. This should be plenty, as I'm unware of any hardware we currently run in which supports more than 8 CPUs. Notes: svn path=/head/; revision=112809
* - Add vm_paddr_t, a physical address type. This is required for systemsJake Burkholder2003-03-251-0/+1
| | | | | | | | | | | | | | | | | | where physical addresses larger than virtual addresses, such as i386s with PAE. - Use this to represent physical addresses in the MI vm system and in the i386 pmap code. This also changes the paddr parameter to d_mmap_t. - Fix printf formats to handle physical addresses >4G in the i386 memory detection code, and due to kvtop returning vm_paddr_t instead of u_long. Note that this is a name change only; vm_paddr_t is still the same as vm_offset_t on all currently supported platforms.

* Made the prototypes for pmap_kenter and pmap_kremove MD. These functionsJake Burkholder2003-03-161-0/+2
| | | | | | | | | | | | are machine dependent because they are not required to update the tlb when mappings are added or removed, and doing so is machine dependent. In addition, an implementation may require that pages mapped with pmap_kenter have a backing vm_page_t, which is not necessarily true of all physical pages, and so may choose to pass the vm_page_t to pmap_kenter instead of the physical address in order to make this requirement clear.

* Remove support for running in SimOS. The support has rotted overMarcel Moolenaar2003-02-251-10/+0
| | | | | | | | | | | time and there's no indication that it will improve anytime soon. By removing support for SimOS it is possible to build LINT on Alpha, which is considered more important at the moment. Not objected to on: alpha@ Notes: svn path=/head/; revision=111457
* Workaround for compiling LINT. Large kernels (like LINT) can haveMarcel Moolenaar2003-02-231-20/+32
| | | | | | | | | | | | | | branch targets that are too far apart for the BRADDR relocation. This is caused by the branch prediction optimizationi in the atomic inlines here, because they jump across sections. The workaround is to suppress jumping to a different section when compiling LINT. To generate correct code in that case, the section directives are replaced by a branch and a label to deal with the fall-through case. Reasonably good C compilers will optimize this away anyway, so the end result isn't really that bad. Notes: svn path=/head/; revision=111295

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | o Add a MD header private to libc called _fpmath.h; this header contains bitfield layouts of MD floating-point types. o Add a MI header private to libc called fpmath.h; this header contains bitfield layouts of MI floating-point types. o Add private libc variables to lib/libc/$arch/gen/infinity.c for storing NaN values. o Add __double_t and __float_t to <machine/_types.h>, and provide double_t and float_t typedefs in <math.h>. o Add some C99 manifest constants (FP_ILOGB0, FP_ILOGBNAN, HUGE_VALF, HUGE_VALL, INFINITY, NAN, and return values for fpclassify()) to <math.h> and others (FLT_EVAL_METHOD, DECIMAL_DIG) to <float.h> via <machine/float.h>. o Add C99 macro fpclassify() which calls __fpclassify{d,f,l}() based on the size of its argument. __fpclassifyl() is never called on alpha because (sizeof(long double) == sizeof(double)), which is good since __fpclassifyl() can't deal with such a small `long double'. This was developed by David Schultz and myself with input from bde and fenner.

* Implement bus_dmamem_alloc_size() and bus_dmamem_free_size() asScott Long2003-01-291-0/+6
| | | | | | | | | | | | | | | | | | | | | | | counterparts to bus_dmamem_alloc() and bus_dmamem_free(). This allows the caller to specify the size of the allocation instead of it defaulting to the max_size field of the busdma tag. This is intended to aid in converting drivers to busdma. Lots of hardware cannot understand scatter/gather lists, which forces the driver to copy the i/o buffers to a single contiguous region before sending it to the hardware. Without these new methods, this would require a new busdma tag for each operation, or a complex internal allocator/cache for each driver. Allocations greater than PAGE_SIZE are rounded up to the next PAGE_SIZE by contigmalloc(), so this is not suitable for multiple static allocations that would be better served by a single fixed-length subdivided allocation.

| | | | | | | | | | | | | | | | | | | handling clean and functional as 5.x evolves. This allows some of the nasty bandaids in the 5.x codepaths to be unwound. Encapsulate 4.x signal handling under COMPAT_FREEBSD4 (there is an anti-foot-shooting measure in place, 5.x folks need this for a while) and finish encapsulating the older stuff under COMPAT_43. Since the ancient stuff is required on alpha (longjmp(3) passes a 'struct osigcontext *' to the current sigreturn(2), instead of the 'ucontext_t *' that sigreturn is supposed to take), add a compile time check to prevent foot shooting there too.

While moving them, make a few adjustments (submitted by bde): o __ct_rune_t needs to be precisely `int', not necessarily __int32_t, since the arg type of the ctype functions is int. o __rune_t, __wchar_t and __wint_t inherit this via a typedef of __ct_rune_t. o Some minor wording changes in the comment blocks for ct_rune_t and mbstate_t.
