* Celebrate OpenBSD 6.0 release by retiring the sparc port.tedu2016-09-011-232/+0
| | | | | You've served us well, good friend, but now it's time to rest. ok deraadt
* Now that the kernel virtual address space has been made larger, even onmiod2015-11-051-2/+2
| | | | | sun4/4c/4e, increase NKMEMPAGES_MAX_DEFAULT to the same value as platforms with limited, but not horribly limited, kva size.
* Add a bus_dma_tag_t for DVMA usage, suitable for use for devices not sittingmiod2015-03-301-3/+2
| | | | | | | | | | | | | | | | | behind a sun4m iommu. Move the existing dvma routines from vm_machdep.c to this new dvma.c; this allows for a few declarations to be removed from public headers. Extend the device attachment arguments (struct confargs) to pass a bus_dma_tag_t. mainbus receives the dvma bus_dma_tag_t, and devices pass the tag unchanged to their children, except for iommu(4) which replaces it with its own. Change the few sun4m-only drivers to pick the bus_dma_tag_t from confargs rather than assume iommu; this allows qlw(4) to attach and work on sun4c. ok kettenis@
* Rework the virtual memory layout on SRMMU systems (sun4d/sun4m) to use a muchmiod2015-03-181-3/+1
| | | | | | | | | | | | | | | | | | | | | lower VM_MIN_KERNEL_ADDRESS, since these systems are not crippled by the Sun-4 MMU hole and have the real 4GB of address space. Kernels running on Sun-4 MMU are not affected and will still be restricted to the existing 128MB of kernel space, with 1GB - 128MB of user space. Kernels running on SRMMU will now provide the low 3GB of address space to userland, and use the top 1GB for the kernel, except when compiled with option SMALL_KERNEL, in which case they will keep Sun-4 style the layout (this is temporary to allow for people to boot bsd.rd to upgrade even when not running 2.10 boot blocks, and will be removed eventually) A consequence of this is that the top of the userland stack is no longer at 0xf0000000. But since nothing in userland uses USRSTACK anymore, this should not be an issue. Tested on sun4c and various sun4m, with physical memory sizes ranging from 32 to 448MB.
* PGSHIFT and PGOFSET are now contained inside the kernel namespace.deraadt2013-03-261-3/+3

* refactor sys/param.h and machine/param.h. A lot of #ifdef _KERNEL is addedderaadt2013-03-231-94/+84
| | | | | | | to keep definitions our of user space. The MD files now follow a consistant order -- all namespace intrusion is at the tail can be cleaned up independently. locore, bootblocks, and libkvm still see enough visibility to build. Checked on 90% of platforms...
* Provide namespace-safe alignment macros in <machine/_types.h>, withguenther2011-09-081-15/+4
| | | | | | | | compat names kept in <machine/param.h>. In <sys/socket.h>, pull in <sys/_types.h> instead of the namespace polluting <machine/param.h> and completely eliminate __CMSG_ALIGN, replaced by _ALIGN ok deraadt@

* Move the MSIZE, MCLSHIFT, MCLBYTES and the MCLOFSETthib2007-05-281-9/+1
| | | | | | | | | | | mbuf constants from MD param.h to MI param.h. Besides being the same on every arch, things will most probly break if any arch has different values then the others. The NMBCLUSTERS constants needs to be MD though; ok miod@,krw@,claudio@

* Make all DEV_BSIZE definitions consistant by using (1 << DEV_BSHIFT)krw2006-08-121-2/+2

| | | | | arches; except on sparc where the range is 4-8 for !sun4m and 4-64 for sun4m, selected at runtime.

* On sparc, PAGE_SIZE and friends might not be a compile-time constant.miod2002-03-131-35/+25
| | | | | | | | | | Instead of using a homegrown set of variables in this case, rely on uvmexp fields once uvm has been initialized. This requires a few #include <uvm/uvm_extern.h> here and there in the kernel as well. Idea from art@, changes by me.
* Provide PAGE_{MASK,SHIFT,SIZE} ``constants'' for every cpu combination.miod2002-02-191-1/+13

* Define MCLBYTES from MCLSHIFT, rather than providing the final value.miod2001-12-101-2/+2

* make nkmempages dynamic based on memory. okay art@ from netbsd:provos2001-12-051-5/+5
| | | | | | | | | | | | | | date: 2000/02/11 19:22:52; author: thorpej; Add some very simple code to auto-size the kmem_map. We take the amount of physical memory, divide it by 4, and then allow machine dependent code to place upper and lower bounds on the size. Export the computed value to userspace via the new "vm.nkmempages" sysctl. NKMEMCLUSTERS is now deprecated and will generate an error if you attempt to use it. The new option, should you choose to use it, is called NKMEMPAGES, and two new options NKMEMPAGES_MIN and NKMEMPAGES_MAX allow the user to configure the bounds in the kernel config file.
* Get rid of the PMAP_NEW option by making it mandatory for all archs.art2001-07-181-3/+1
| | | | | The archs that didn't have a proper PMAP_NEW now have a dummy implementation with wrappers around the old functions.

* Switch sparc to PMAP_NEW. I've been running with that code for ages.art2001-05-101-1/+3

* Get rid of CLSIZE and all related stuff.art2001-05-051-8/+4
| | | | | | | | | CLSIZE -> 1 CLBYTES -> PAGE_SIZE OLOFSET -> PAGE_MASK etc. At the same time some archs needed some cleaning in vmparam.h so that goes in at the same time.
* - increase the amount of space mapped for dvma on sun4mjason2001-01-151-2/+3
| | | | | | | | - use a flag to specify allocations for 24 bit devices - compatibility macros to deal with the 32 bit devices This fixes the 'le at sbus' on sun4m problem (with the extent fixes earlier), and allows the Artecon ethernet cards to work in sun4m machines.
