934f2f338c Make sure the boot2 stage is compiled with gcc, as clang has no
problems compiling it, but it just gets too big at the moment, even
with -Os.  This is not applicable to gptboot, though.

Correctly setup LDADD with regards to libstand.

676799a00d completely ignore zero-sized elf sections in modules of elf object type (amd64)
Current code doesn't check size of elf sections and may perform needless
actions of zero-sized memory allocation and similar.
The bigger issue is that alignment requirement of a zero-sized section
gets effectively applied to the next section if it has smaller alignment
requirement.  But other tools, like gdb and consequently kgdb,
completely ignore zero-sized sections and thus may map symbols to
addresses differently.

Zero-sized sections are not typical in general.
Their typical (only, even) cause in FreeBSD modules is inline assembly that
creates custom sections which is found in pcpu.h and vnet.h.  Mere inclusion
of one of those header files produces a custom section in elf output.
If there is no actual use for the section in a given module, then the
section remains empty.

Better solution is to avoid creating zero-sized sections altogether,
which is in plans.

Preloaded modules are handled in boot code (load_elf_obj.c), while
dynamically loaded modules are handled by kernel (link_elf_obj.c).

7d54a05ac8 Correctly setup LDADD with regards to libstand. The submitter points
out that "on amd64, libstand.a is compiled for i386, but is still installed
under ${WORLDTMP}/usr/lib instead of ${WORLDTMP}/usr/lib32.  Even if it
would be installed there, ld on amd64 is set up incorrectly with a
${TOOLS_PREFIX}/usr/lib/i386 default path, so it wouldn't link.  The reason
it does link under gcc is that gcc passes -L${WORLDTMP}/usr/lib twice,
even for -m32 builds, which is also incorrect, but accidentally works in
this case."

d193ed0bed Add driver for Silicon Integrated Systems SiS190/191 Fast/Gigabit Ethernet.
This driver was written by Alexander Pohoyda and greatly enhanced
by Nikolay Denev. I don't have these hardwares but this driver was
tested by Nikolay Denev and xclin.

Because SiS didn't release data sheet for this controller, programming
information came from Linux driver and OpenSolaris. Unlike other open
source driver for SiS190/191, sge(4) takes full advantage of TX/RX
checksum offloading and does not require additional copy operation in
RX handler.
The controller seems to have advanced offloading features like VLAN
hardware tag insertion/stripping, TCP segmentation offload(TSO) as
well as jumbo frame support but these features are not available
yet. Special thanks to xclin <xclin<> cs dot nctu dot edu dot tw>

but also of different types, f.e. Sun Fire V890 can be equipped with a
mix of UltraSPARC IV and IV+ CPUs, requiring different MMU initialization

CPU implementation number from a global variable to the per-CPU data.
Functions which are called before the latter is available are passed the

606e071c41 Use the SUNW,{d,i}tlb-load methods for entering locked TLB entries like
OpenBSD and OpenSolaris do instead of fiddling with the MMUs ourselves.
Unlike direct access the firmware methods don't automatically use the
next free (?) TLB slot, instead the slot to be used has to be specified.
We allocate the TLB slots for the kernel top-down as OpenSolaris suggests
that the firmware will always allocate the ones for its own use bottom-up.
Besides being simpler, according to OpenBSD using the firmware methods is
required to allow booting on Sun Fire E10K with multi-systemboard domains.

4f607e8ef2 - Assert that HEAPSZ is a multiple of PAGE_SIZE as at least the firmware
of Sun Fire V1280 doesn't round up the size itself but instead lets
  claiming of non page-sized amounts of memory fail.
- Change parameters and variables related to the TLB slots to unsigned
  which is more appropriate.
- Search the whole OFW device tree instead of only the children of the
  root nexus device for the BSP as starting with UltraSPARC IV the 'cpu'
  nodes hang off of from 'cmp' (chip multi-threading processor) or 'core'
  or combinations thereof. Also in large UltraSPARC III based machines
  the 'cpu' nodes hang off of 'ssm' (scalable shared memory) nodes which
  group snooping-coherency domains together instead of directly from the
  nexus.
- Add support for UltraSPARC IV and IV+ BSPs. Due to the fact that these
  are multi-core each CPU has two Fireplane config registers and thus the
  module/target ID has to be determined differently so the one specific
  to a certain core is used. Similarly, starting with UltraSPARC IV the
  individual cores use a different property in the OFW device tree to
  indicate the CPU/core ID as it no longer is in coincidence with the
  shared slot/socket ID.
  While at it additionally distinguish between CPUs with Fireplane and
  JBus interconnects as these also use slightly different sizes for the
  JBus/agent/module/target IDs.
- Check the return value of init_heap(). This requires moving it after
  cons_probe() so we can panic when appropriate. This should be fine as
  the PowerPC OFW loader uses that order for quite some time now.

716f79c093 Remove file system support based on the simple file system protocol
as this only allows us to access file systems that EFI knows about.
With a loader that can only use EFI-supported file systems, we're
forced to put /boot on the EFI system partition. This is suboptimal
in the following ways:
1.  With /boot a symlink to /efi/boot, mergemaster complains about
    the mismatch and there's no quick solution.
2.  The EFI loader can only boot a single version of FreeBSD. There's
    no way to install multiple versions of FreeBSD and select one
    at the loader prompt.
3.  ZFS maintains /boot/zfs/zpool.cache and with /boot a symlink we
    end up with the file on a MSDOS file system. ZFS does not have
    proper handling of file systems that are under Giant.

Implement a disk device based on the block I/O protocol instead and
pull in file system code from libstand. The disk devices are really
the partitions that EFI knows about.

This change is backward compatible.

ccb1921ee0 - Add code allowing a network device to only be open and closed once
by keeping it opened after the first open and closing it via the
  cleanup handler when NETIF_OPEN_CLOSE_ONCE is defined in order to
  avoid the open-close-dance on every file access which with firmware
  that for example performs an auto-negotiation on every open causes
  netbooting to take horribly long. Basically the behavior with this
  knob enabled resembles the one employed between r60506 and r177108
  (and for sparc64 also again since r182919) with the addition that
  the network device now is closed eventually before entering the
  kernel and before rebooting. Actually I think this should be the
  desired MI behavior, however the U-Boot loader actually requires
  net_close() to be called after every transaction in order for some
  local shutdown operations to be performed (and which I think thus
  will break on concurrent opens, i.e. when netdev_opens is > 1, like
  the loader does at least for disks when LOADER_GZIP_SUPPORT is
  enabled).
- Use NETIF_OPEN_CLOSE_ONCE to replace the hack, which artificially
  increased netdev_opens for sparc64 in order to keep the network
  device opened forever, as at least some firmware versions require
  the network device to be closed eventually before entering the
  kernel or otherwise will DMA received packets to stale memory.
  The powerpc OFW loader probably wants NETIF_OPEN_CLOSE_ONCE to be
  set as well for the same reasons.

4497287f20 - Port bios_getmem() from libi386 to {gpt,}zfsboot() and use it to
safely allocate a heap region above 1MB.  This enables {gpt,}zfsboot()
  to allocate much larger buffers than before.
- Use a larger buffer (1MB instead of 128K) for temporary ZFS buffers.  This
  allows more reliable reading of compressed files in a raidz/raidz2 pool.

f1a6fd5d07 Improve the algorithm the loader uses to choose a memory range for its
heap when using a range above 1MB.

Previously the loader would always use the last 3MB in the first memory
range above 1MB for the heap.  However, this memory range is also where the
kernel and any modules are loaded.  If this memory range is "small", then
using the high 3MB for the heap may not leave enough room for the kernel
and modules.

Now the loader will use any range below 4GB for the heap, and the logic to
choose the "high" heap region has moved into biosmem.c.  It sets two
variables that the loader can use for a high heap if it desires.  When a
high heap is enabled (BZIP2, FireWire, GPT, or ZFS), then the following
memory ranges are preferred for the heap in order from best to worst:
- The largest memory region in the SMAP with a start address greater than
  1MB.  The memory region must be at least 3MB in length.  This leaves the
  region starting at 1MB purely for use by the kernel and modules.
- The last 3MB of the memory region starting at 1MB if it is at least 3MB
  in size.  This matches the current behavior except that the current loader
  would break horribly if the first region was not at least 3MB in size.
- The memory range from the end of the loader up to the 640k window.  This
  is the range the loader uses when none of the high-heap-requesting options
  are enabled.

f06c961ee3 Create a seperate ZFS enabled loader.
This adds zfsloader which will be called by zfsboot/gptzfsboot code rather
than the tradional loader.  This eliminates the need to set the
LOADER_ZFS_SUPPORT variable in order to get a ZFS enabled loader.

Note however, that you must reinstall your bootcode (zfsboot/gptzfsboot)
in order for the boot process to use the new loader.

New installations will no longer be required to build a ZFS enabled
loader for a working ZFS boot system.  Installing zfsboot/gptzfsboot is
sufficient for acknowledging the use of CDDL code and therefore the ZFS
enabled loader.

That results useful when using serial lines sending garbage and leading
to unwilling boot prompt appearence.

14c436e101 Correct some issues with zfs boot.
- Teach it to read gang blocks. (essentially untested)
   If you see "ZFS: gang block detected!", please let
   me know, so we can either remove the printf if it
   works, or fix it if it doesn't.

 - If multiple partitions exist on a disk, probe them all.
   We also need to reset dsk->start to 0 to read the right
   sector here.

 - With GPT, we can have 128 partitions.

 - If the bootfs property has ever been set on a pool
   it seems that it never goes away.  zpool won't allow
   you to add to the pool with the bootfs property set.
   However, if you clear the property back to default
   we end up getting 0 for the object number and read
   a bogus block pointer and fail to boot.

 - Fix some error printfs. The printf in the loader is
   only capable of c,s and u formats.

 - Teach printf how to display %llu

a944fb4cc3 Use zfs_read() instead of xfsread() to read /boot.config. xfsread() fails
short read requests, so the result was that a /boot.config smaller than 512
bytes was ignored.  boot2 uses fsread() instead of xfsread() to read
/boot.config already, so this makes zfsboot more like boot2.

4507f02e0e lindev(4) [1] is supposed to be a collection of linux-specific pseudo
devices that we also support, just not by default (thus only LINT or
module builds by default).

While currently there is only "/dev/full" [2], we are planning to see more
in the future.  We may decide to change the module/dependency logic in the
future should the list grow too long.

This is not part of linux.ko as also non-linux binaries like kFreeBSD
userland or ports can make use of this as well.

d0ea47437a Update epair(4) to the new netisr implementation and polish
things a bit:
- use dpcpu data to track the ifps with packets queued up,
- per-cpu locking and driver flags
- along with .nh_drainedcpu and NETISR_POLICY_CPU.
- Put the mbufs in flight reference count, preventing interfaces
  from going away, under INVARIANTS as this is a general problem
  of the stack and should be solved in if.c/netisr but still good
  to verify the internal queuing logic.
- Permit changing the MTU to virtually everythinkg like we do for loopback.
