* Make room for media types of the future. Extend the ifmedia word to 64 bits.stsp2015-09-111-4/+4
| | | | | | | | | | | | | | | | This changes numbers of the SIOCSIFMEDIA and SIOCGIFMEDIA ioctls and grows struct ifmediareq. Old ifconfig and dhclient binaries can still assign addresses, however the 'media' subcommand stops working. Recompiling ifconfig and dhclient with new headers before a reboot should not be necessary unless in very special circumstances where non-default media settings must be used to get link and console access is not available. There may be some MD fallout but that will be cleared up later. ok deraadt miod with help and suggestions from several sharks attending l2k15

While there, don't bother doing this when booting from tape. This works around the sun4e PROM 1.6, which gets confused by PROM open() - close() sequences without any I/O happening in between. Crank boot blocks version to 2.11.

| | | | | | | | | | | delete coredump_trad(), uvm_coredump(), cpu_coredump(), struct md_coredump, and various #includes that are superfluous. This leaves compat_linux processes without a coredump callback. If that ability is desired, someone should update it to use coredump_elf32() and verify the results... ok kettenis@

| | | | | | | | | | | | | | | | | 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@

| | | | | | | | | in order to give these systems a more reasonable amount of kva, yet still providing .75GB to userland processes. Although there is no dependency upon a recent boot loader on non-SRMMU systems, SMALL_KERNEL will nevertheless stick to the legacy kvm layout, for the time being.

| | | | | | | | | | | reachable with the default slot aperture (such as hme(4) devices, which have their registers at offset 0x08c00000 from the slot base), force the attachment of the device to fail. While hme would fail early due to being unable to talk on the mdio bus, hme+esp boards would have the esp part of the board get nuts and would spin during autoconf. Of course, you are not supposed to use such boards on sun4c, because (as mentioned above) they can't run without an iommu.
* Rework the virtual memory layout on SRMMU systems (sun4d/sun4m) to use a muchmiod2015-03-188-89/+173
| | | | | | | | | | | | | | | | | | | | | 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.

Since bootxx only needs printf for very simple panic() message involving %s and %d format specifiers only, compile a -DSTRIPPED version of printf.c for the use of bootxx. This makes bootxx return to a manageable size (it is even 8 bytes shorter now).

| | | | | | | | | | | | | | | more megabyte of virtual memory beyond the kernel image; this is safe to do as you can't find any such system with less than 8MB of contiguous memory. While nothing in the kernel has a need for that extra memory to be available to the kernel for its bootstrap needs, forthcoming changes (post-5.7) will need it, and these kernels won't work when booted from boot loaders prior to this change. By shipping 5.7 with updated boot blocks, we'll make upgrading to 5.7-CURRENT easier for sun4m owners, when the time comes. Crank boot blocks version. ok deraadt@
