It's anticipated that after the freeze, this will be removed in

Due to the impending freeze, there was no formal core vote for
this. I've been talking to different core members all day, as well as
Matt Macey and Glen Barber. Nobody is completely happy, all are
grudgingly going along with this. Work is in progress to mitigate

Per-page queue state is updated non-atomically, with either the page
lock or the page queue lock held. When vm_page_dequeue() is called
without the page lock, in rare cases a different thread may be
concurrently dequeuing the page with the pagequeue lock held. Because
of the non-atomic update, vm_page_dequeue() might return before queue
state is completely updated, which can lead to race conditions.
Restrict the vm_page_dequeue() interface so that it must be called
either with the page lock held or on a free page, and busy wait when
a different thread is concurrently updating queue state, which must
happen in a critical section.
While here, do some related cleanup: inline vm_page_dequeue_locked()
into its only caller and delete a prototype for the unimplemented
vm_page_requeue_locked(). Replace the volatile qualifier for "queue"
added in r333703 with explicit uses of atomic_load_8() where required.

a10_timer is currently use in UP allwinner SoC (A10 and A13).
Those don't have the generic arm timer.
The arm generic timecounter is broken in the A64 SoC, some attempts have
been made to fix the glitch but users still reported some minor ones.
Since the A64 (and all Allwinner SoC) still have this timer controller, rework
the driver so we can use it in any SoC.
Since it doesn't have the 64 bits counter on all SoC, use one of the
generic 32 bits counter as the timecounter source.

This also has advantages when building on a FreeBSD host: we now tell

SDHCI_TRNS_ACMD12 is to be set only for multiple-block read/write
commands without data length information, so don't unconditionally
set this bit. The result matches what e. g. Linux does.
- Section 2.2.19 of the SDHCI specification version 4.20 states that
SDHCI_ACMD12_ERR should be only valid if SDHCI_INT_ACMD12ERR is set
and hardware may clear SDHCI_ACMD12_ERR when SDHCI_INT_ACMD12ERR is
cleared (differing silicon behavior is specifically allowed, though).
Thus, read SDHCI_ACMD12_ERR before clearing SDHCI_INT_ACMD12ERR.
While at it, use the 16-bit accessor rather than the 32-bit one for
reading the 16-bit SDHCI_ACMD12_ERR.
- SDHCI_INT_TUNEERR isn't one of the ROC bits in SDHCI_INT_STATUS so
clear it explicitly.
- Add missing prototypes and sort them.
While loader.conf(5) suggests that all values should be quoted, reality is
that this was never strictly enforced and it is used. We already make some
concession to this in number values, which aren't strictly quoted either.
The compromise here is that multi-word values must be quoted. This lets
things like `foo_load=YES` work, while denying more complex expressions on
the right hand side. This likely catches the vast majority of current usage.
A bit of a kludge is needed to accomplish this since Lua regex doesn't
support branching. I had considered splitting up expressions and generating
the right-hand side of the expressions completely in config.parse, but
deemed this too large of an overhaul to take given the current timing. This
should be re-worked shortly after the thaw.

The value of 128 chosen is a balance between being big enough to
reduce potential precision/quantization effects stemming from frequent
bucket refills over small time intervals and being small enough to
prevent a greedy driver from burst dequeuing more packets than it has

The current kernel ifunc implementation creates a PLT entry for each
ifunc definition. ifunc calls therefore consist of a call to the
PLT entry followed by an indirect jump. The jump target is written
during boot when the kernel linker resolves R_[*]_IRELATIVE relocations.
This implementation is defined by requirements for userland code, where
text relocations are avoided. This requirement is not present for the
kernel, so the implementation has avoidable overhead (namely, an extra
indirect jump per call).
Address this for now by adding a special option to the static linker
to inhibit PLT creation for ifuncs. Instead, relocations to ifunc call
sites are passed through to the output file, so the kernel linker can
enumerate such call sites and apply PC-relative relocations directly
to the text section. Thus the overhead of an ifunc call becomes exactly
the same as that of an ordinary function call. This option is only for
use by the kernel and will not work for regular programs.
The final form of this optimization is up for debate; for now, this
change is simple and static enough to be acceptable as an interim
solution.

manu found in the noted PR that overlays seemed to be clobbering the kenv
and killing the boot. Further inspection revealed that one can `fdt ls` at
the loader prompt for a successful boot, but autoboot breaks it.
In the autoboot case, first setup of FDT is happening in the middle of
bi_load, which triggers loading of the DTBO from /boot.
This is bad, bad, bad. Files in the loader are loaded somewhere in the
middle of the address space one after another. bi_load starts building the
needed kernel bootinfo immediately after the highest-addr loaded file. File
loads in the middle of bi_load suddenly clobber bootinfo and everything goes
off the rails.
The solution to this is to use take advantage of arch_autoload to setup FDT
in efiloader compiled with LOADER_FDT_SUPPORT. This matches how it works in
ubldr land, and is how it should have worked when overlay support was added
to efiloader since fdt_setup_fdtp now has the potential to load files
(courtesy of fdt_platform_load_dtb).

- Most of the boards are using U-Boot, u-boot embed a DTB that isn't
compiled with -@ (overlay ready) so we cannot use overlays. We want
overlays, overlays are nice.
- The DTS life is going to linux, then sometimes it's imported in
U-Boot but it depend on the SoC family, U-Boot doesn't batch import
every DTS like we do. So sometimes to U-Boot DTS are very old. Or when
an interesting patch in commited upstream it is in Linux X+2 (roughly 4
months from now), we then have to wait for U-Boot to catch up, that
give us between 4 and 6 months to have an update.
- Some boards like the Marvell ones have 3 DTS, the one in the
vendor U-Boot made by Marvell themselves, the one in u-boot mainline
and the one in Linux. I found that the DTS in the Marvell U-Boot have
some problem with FreeBSD (especially the macchiatobin that declare
node with the same address but not the same size, that is not something
that the rman code can handle, it could be modified, I don't know the
code well enough). Also some compatible are used when they shouldn't,
for example they declare the gpio being orion-gpio while this binding
requires interrupts supports, which the node doesn't have.
- The above situation is mostly the same with RockChip SoCs (possibly
others, those are the only SoCs I work on that have this problem).
Note that importing the DTS doesn't mean that every board will use
them, I don't intend to copy the DTB to the GENERIC memstick image for
the Overdrive 1000/3000 for example, the ones provided by the firmware
works fine.
RPI3 will still stay an exception as we use the DTB provided by the
rpi-firmware package, so they come from the rpi foundation linux fork.
