Apple's EFI drivers supply device properties which are needed to support
Macs optimally. They contain vital information which cannot be obtained
any other way (e.g. Thunderbolt Device ROM). They're also used to convey
the current device state so that OS drivers can pick up where EFI
drivers left (e.g. GPU mode setting).
There's an EFI driver dubbed "AAPL,PathProperties" which implements a
per-device key/value store. Other EFI drivers populate it using a custom
protocol. The macOS bootloader /System/Library/CoreServices/boot.efi
retrieves the properties with the same protocol. The kernel extension
AppleACPIPlatform.kext subsequently merges them into the I/O Kit
registry (see ioreg(8)) where they can be queried by other kernel
extensions and user space.
This commit extends the efistub to retrieve the device properties before
ExitBootServices is called. It assigns them to devices in an fs_initcall
so that they can be queried with the API in <linux/property.h>.
Note that the device properties will only be available if the kernel is
booted with the efistub. Distros should adjust their installers to
always use the efistub on Macs. grub with the "linux" directive will not
work unless the functionality of this commit is duplicated in grub.
(The "linuxefi" directive should work but is not included upstream as of
this writing.)
The custom protocol has GUID 91BD12FE-F6C3-44FB-A5B7-5122AB303AE0 and
looks like this:
typedef struct {
unsigned long version; /* 0x10000 */
efi_status_t (*get) (
IN struct apple_properties_protocol *this,
IN struct efi_dev_path *device,
IN efi_char16_t *property_name,
OUT void *buffer,
IN OUT u32 *buffer_len);
/* EFI_SUCCESS, EFI_NOT_FOUND, EFI_BUFFER_TOO_SMALL */
efi_status_t (*set) (
IN struct apple_properties_protocol *this,
IN struct efi_dev_path *device,
IN efi_char16_t *property_name,
IN void *property_value,
IN u32 property_value_len);
/* allocates copies of property name and value */
/* EFI_SUCCESS, EFI_OUT_OF_RESOURCES */
efi_status_t (*del) (
IN struct apple_properties_protocol *this,
IN struct efi_dev_path *device,
IN efi_char16_t *property_name);
/* EFI_SUCCESS, EFI_NOT_FOUND */
efi_status_t (*get_all) (
IN struct apple_properties_protocol *this,
OUT void *buffer,
IN OUT u32 *buffer_len);
/* EFI_SUCCESS, EFI_BUFFER_TOO_SMALL */
} apple_properties_protocol;
Thanks to Pedro Vilaça for this blog post which was helpful in reverse
engineering Apple's EFI drivers and bootloader:
https://reverse.put.as/2016/06/25/apple-efi-firmware-passwords-and-the-scbo-myth/
If someone at Apple is reading this, please note there's a memory leak
in your implementation of the del() function as the property struct is
freed but the name and value allocations are not.
Neither the macOS bootloader nor Apple's EFI drivers check the protocol
version, but we do to avoid breakage if it's ever changed. It's been the
same since at least OS X 10.6 (2009).
The get_all() function conveniently fills a buffer with all properties
in marshalled form which can be passed to the kernel as a setup_data
payload. The number of device properties is dynamic and can change
between a first invocation of get_all() (to determine the buffer size)
and a second invocation (to retrieve the actual buffer), hence the
peculiar loop which does not finish until the buffer size settles.
The macOS bootloader does the same.
The setup_data payload is later on unmarshalled in an fs_initcall. The
idea is that most buses instantiate devices in "subsys" initcall level
and drivers are usually bound to these devices in "device" initcall
level, so we assign the properties in-between, i.e. in "fs" initcall
level.
This assumes that devices to which properties pertain are instantiated
from a "subsys" initcall or earlier. That should always be the case
since on macOS, AppleACPIPlatformExpert::matchEFIDevicePath() only
supports ACPI and PCI nodes and we've fully scanned those buses during
"subsys" initcall level.
The second assumption is that properties are only needed from a "device"
initcall or later. Seems reasonable to me, but should this ever not work
out, an alternative approach would be to store the property sets e.g. in
a btree early during boot. Then whenever device_add() is called, an EFI
Device Path would have to be constructed for the newly added device,
and looked up in the btree. That way, the property set could be assigned
to the device immediately on instantiation. And this would also work for
devices instantiated in a deferred fashion. It seems like this approach
would be more complicated and require more code. That doesn't seem
justified without a specific use case.
For comparison, the strategy on macOS is to assign properties to objects
in the ACPI namespace (AppleACPIPlatformExpert::mergeEFIProperties()).
That approach is definitely wrong as it fails for devices not present in
the namespace: The NHI EFI driver supplies properties for attached
Thunderbolt devices, yet on Macs with Thunderbolt 1 only one device
level behind the host controller is described in the namespace.
Consequently macOS cannot assign properties for chained devices. With
Thunderbolt 2 they started to describe three device levels behind host
controllers in the namespace but this grossly inflates the SSDT and
still fails if the user daisy-chained more than three devices.
We copy the property names and values from the setup_data payload to
swappable virtual memory and afterwards make the payload available to
the page allocator. This is just for the sake of good housekeeping, it
wouldn't occupy a meaningful amount of physical memory (4444 bytes on my
machine). Only the payload is freed, not the setup_data header since
otherwise we'd break the list linkage and we cannot safely update the
predecessor's ->next link because there's no locking for the list.
The payload is currently not passed on to kexec'ed kernels, same for PCI
ROMs retrieved by setup_efi_pci(). This can be added later if there is
demand by amending setup_efi_state(). The payload can then no longer be
made available to the page allocator of course.

Set the default highlight language to "none", i.e. do not try to guess
the language and do automatic syntax highlighting on literal blocks.
Eyeballing around the generated documentation, we don't seem to actually
have a lot of literal blocks that would benefit from syntax
highlighting. The C code blocks we do have are typically very short, and
most of the literal blocks are things that shouldn't be highlighted (or,
do not have a pygments lexer). This seems to be true for literal blocks
both in the rst source files and in source code comments.
Not highlighting code is never wrong, but guessing the language wrong
almost invariably leads to silly or confusing highlighting.
At the time of writing, admin-guide/oops-tracing.rst and
admin-guide/ramoops.rst contain good examples of 1) a small C code
snippet not highlighted, 2) a hex dump highligted as who knows what, 3)
device tree block highlighted as C or maybe Python, 4) a terminal
interaction highlighted as code in some language, and finally, 5) some C
code snippets correctly identified as C. I think we're better off
disabling language guessing, and going by explicitly identified
languages for longer code blocks.
It is still possible to enable highlighting on an rst source file basis
using the highlight directive:
.. higlight:: language
and on a literal block basis using the code-block directive:
.. code-block:: language

Signed-off-by: David S. Miller <davem@davemloft.net>
The default sched_clock() implementation is native_sched_clock(). It
contains code to handle non constant frequency TSCs, which creates
overhead for systems with constant frequency TSCs.
The vmware hypervisor guarantees a constant frequency TSC, so
native_sched_clock() is not required and slower than a dedicated function
which operates with one time calculated conversion factors.
Calculate the conversion factors at boot time from the tsc frequency and
install an optimized sched_clock() function via paravirt ops.
The paravirtualized clock can be disabled on the kernel command line with
the new 'no-vmw-sched-clock' option.

The creation of the admin and process guides is a great thing, but, without
care, we risk replacing a messy docs directory with a few messy Sphinx
books. In an attempt to head that off and show what I'm thinking, here's a
set of tweaks that, I think, make the existing Sphinx-formatted docs a bit
more accessible.
It does no good to mention The 2.4 kernel series and neglect
USB 3.x and XHCI. Also with type C and micro/mini USB we better
not talk about the shape of connectors.

The admin guide is a good start, but it's time to turn it into something
better than an unordered blob of files. This is a first step in that
direction. The TOC has been split up and annotated, the guides have been
reordered, and minor tweaks have been applied to a few of them.
One consequence of splitting up the TOC is that we don't really want to use
:numbered: anymore, since the count resets every time and there doesn't
seem to be a way to change that. Eventually we probably want to group the
documents into sub-books, at which point we can go back to a single TOC,
but it's probably early to do that.

For mostly historical reasons, the x86 oops dump shows the raw stack
values:
...
[registers]
Stack:
ffff880079af7350 ffff880079905400 0000000000000000 ffffc900008f3ae0
ffffffffa0196610 0000000000000001 00010000ffffffff 0000000087654321
0000000000000002 0000000000000000 0000000000000000 0000000000000000
Call Trace:
...
This seems to be an artifact from long ago, and probably isn't needed
anymore. It generally just adds noise to the dump, and it can be
actively harmful because it leaks kernel addresses.
Linus says:
"The stack dump actually goes back to forever, and it used to be
useful back in 1992 or so. But it used to be useful mainly because
stacks were simpler and we didn't have very good call traces anyway. I
definitely remember having used them - I just do not remember having
used them in the last ten+ years.
Of course, it's still true that if you can trigger an oops, you've
likely already lost the security game, but since the stack dump is so
useless, let's aim to just remove it and make games like the above
harder."
This also removes the related 'kstack=' cmdline option and the
'kstack_depth_to_print' sysctl.

It is useless as it dumps the MSRs too early BUT(!) we do set MSRs later too.
Also, it dumps only BSP MSRs as it gets called only for CPU 0.
And the MSR range array would need constant updating anyway, and so on

Oh, and we have msr.ko and msr-tools which are the much better solution
anyway. So off it goes...

Probably, unicode is something that we might remove from the
docs, as all modern systems support it. Yet, this chapter
is fun, as it mentions support for the Klington fictional
charset ;)
On the other hand, I bet all other OS user manuals
explicit mention unicode support.
So, convert it to ReST and include it at the user's book.

Pull timer updates from Thomas Gleixner:
"This updates contains:
- A revert which addresses a boot failure on ARM Sun5i platforms
- A new clocksource driver, which has been delayed beyond rc1 due to
an interrupt driver issue which was unearthed by this driver. The
debugging of that issue and the discussion about the proper
solution made this driver miss the merge window. There is no point
in delaying it for a full cycle as it completes the basic mainline
support for the new JCore platform and does not create any risk
outside of that platform"

Pull vmap stack fixes from Ingo Molnar:
"This is fallout from CONFIG_HAVE_ARCH_VMAP_STACK=y on x86: stack
accesses that used to be just somewhat questionable are now totally
buggy.
These changes try to do it without breaking the ABI: the fields are
left there, they are just reporting zero, or reporting narrower
information (the maps file change)"

mm: Change vm_is_stack_for_task() to vm_is_stack_for_current()
fs/proc: Stop trying to report thread stacks
fs/proc: Stop reporting eip and esp in /proc/PID/stat
mm/numa: Remove duplicated include from mprotect.c
I made a mistake as for naming for this block. The MIO block is not
implemented for these 3 SoCs in the first place. The current naming
will be a trouble if an SoC with both MIO and SD-ctrl blocks appear
in the future.
This driver has just been merged in the previous merge window.
Rename it before the release.
