[PATCH 00/11] x86/microcode: Early load microcode

[Fenghua Yu]

From: Fenghua Yu <fenghua.yu@intel.com>

The problem in current microcode loading method is that we load a microcode way,
way too late; ideally we should load it before turning paging on.  This may only
be practical on 32 bits since we can't get to 64-bit mode without paging on,
but we should still do it as early as at all possible.

Similarly, we should load the microcode update as early as possible during AP
bringup and when processors are brought back online after hotplug or S3/S4.

In order to do that, the microcode patch needs to be permanently present in
kernel memory.  Each individual patch is fairly small, so that is OK, but the
entire blob with support for each CPU is too big. Since only CPU's with same
model can be in the same platform, we store microcode with the same model as
BSP. Later on AP's can upload microcode from the saved microcodep patches.

Note, however, that Linux users have gotten used to being able to install a
microcode patch in the field without having a reboot; we support that model too.

+Early load microcode
+====================
+By Fenghua Yu <fenghua.yu@intel.com>
+
+Kernel can update microcode in early phase of boot time. Loading microcode early
+can fix CPU issues before they are observed during kernel boot time.
+
+Microcode is stored in initrd file. The microcode is read from the initrd file
+and loaded to CPU's during boot time.
+
+The format of the combined initrd image is microcode in cpio format followed by
+initrd image (maybe compressed). Kernel parses the combined initrd image during
+boot time. The microcode file in cpio name space is:
+kernel/x86/microcode/GenuineIntel/microcode.hex
+
+During BSP boot (before SMP starts), if kernel finds the microcode file in the
+initrd file, it parses the microcode and saves matching microcode in memory.
+If matching microcode is found, it will be uploaded in BSP and later on in all
+AP's.
+
+The saved microcode in memory will be used to upload micorcode when system
+resumes from sleep.
+
+In the past, user can issue command to load microcode during run time. There are
+two user space interfaces to load microcode, either through /dev/cpu/microcode
+interface or through reload file in sysfs.
+
+Now user can choose any of the three methods to update microcode during boot
+time or later during run time.
+
+The following sample script shows how to generate a new combined initrd file in
+/boot/initrd-3.5.0.ucode.img with original microcode microcode.hex and
+original initrd image /boot/initrd-3.5.0.img.
+
+mkdir initrd
+cd initrd
+cp ../microcode.hex kernel/x86/microcode/GenuineIntel/microcode.hex
+find .|cpio -oc >../ucode.cpio
+cd ..
+cat ucode.cpio /boot/initrd-3.5.0.img >/boot/initrd-3.5.0.ucode.img
+
+The generated /boot/initrd-3.5.0.ucode.img can be used as initrd file to load
+microcode during early boot time.

Let's call the doc file "early-microcode.txt" like the rest of the
microcode-related files in the tree.

I think you mean the plural "CPUs" here.

Here and below, can we call the microcode file the "microcode container"
to differentiate from the other "file" types?

I guess "uploaded to the BSP" is more fitting here...

 APs.

Simplify:

"The cached microcode patch is applied when the CPU resumes from a sleep state."

"... or through /sys/devices/system/cpu/microcode/reload."

That sounds strange, maybe say something like:

"In addition to those two, the early loading method described here is
the third method with which microcode can be uploaded to a system's
CPUs."

[PATCH 02/11] x86/lib/cpio.c: Find cpio data by its file name

[Fenghua Yu]

From: Fenghua Yu <fenghua.yu@intel.com>

Given a file's name, find its starting point in a cpio formated area. This will
be used to find microcode in combined initrd image. But this function is
generic and could be used in other places.

Shouldn't this (very useful) feature get its own documentation in

Yes, I can document the feature. And if it's generic and useful, this function could be put in generic kernel instead of in x86 arch.

It is useful to override/fix all sort of critical firmware-provided tables,
for example.  ACPI table overrides should use this new cpio-based scheme as
well, and I recall someone wrote something about device tree overrides in a
past thread...

I guess those are speed optimizations on x86, right? In any
case, can we reuse some of the already present ones like
memcmp in <arch/x86/boot/compressed/string.c> and strlen in
<arch/x86/lib/string_32.c>...

and, similarly the generic ones in lib/string.c?

Maybe put all comments above the line they refer to, like above instead
of them trailing?

[PATCH 03/11] x86/microcode_intel.h: Define functions and macros for early load ucode

[Fenghua Yu]

From: Fenghua Yu <fenghua.yu@intel.com>

Define some functions and macros that will be used in early load ucode. Some of
them are moved from microcode_intel.c driver in order to be called in early
boot phase before module can be called.

[PATCH 04/11] x86/microcode_core_early.c: Define interfaces for early load ucode

[Fenghua Yu]

From: Fenghua Yu <fenghua.yu@intel.com>

Define interfaces load_ucode_bsp() and load_ucode_ap() to load ucode on BSP and
AP in early boot time. These are generic interfaces. Internally they call
vendor specific implementations.

Why name it ".hex" when you're loading binary data?  I suggest ".bin".  It
is confusing to have .hex there, since you're not dealing with the Intel HEX
format, nor anything text-like.

I'd say something down the load_ucode_intel_bsp() chain better check the CPU
vendor to make sure the Intel driver won't attempt to load microcode on some
other vendor's processor.

Or are cpu signatures a global namespace and x86 cpu vendors make sure
(past, present and future) to never use the same cpu signature as someone
else is going to use?  Anyway, it would still might be a good thing to do
the vendor check somewhere to avoid wasting time going over every microcode
of the wrong vendor on generic boot images that have both AMD and Intel
microcode.

In this early phase, detecting vendor in initrd is much simpler code. Otherwise, detecting vendor by cpuid (and without cpuid) needs similar but different code as existing functions and coding would be awkward. 

I fully thought and agreed the usage complexity you describe here. It might be good thing to do a bit ugly but more practical coding here.

Thanks.

Sure, there is no harm in defering the implementation of this check to later
versions of the patch set.  As long as the final patch set doesn't risk
loading microcode on the wrong vendor or waste a lot of milliseconds trying
to match intel microcode to a non-intel cpu, I have no objections  :-)

But what about the ".hex" naming for the microcode bundle (container) name?
I find it confusing, since the file contains binary data, not structured
text representing binary data using base 16...  this is also something that
is of minor importance, but at least it is a very easy thing to change at
this point.

I'm confused by this statement.  Getting the vendor from CPUID is a few
lines of code, and non-CPUID processors don't support microcode loading.

Actually I think we can also skip one level of indirection here... no
need to mention "microcode" twice.

kernel/x86/microcode/GenuineIntel or GenuineIntel.bin seems good
enough... the idea here of course is that the string can come from CPUID.

Or,

in case we want to supply more vendor-specific stuff early at boot, we
could do:

kernel/x86/<vendor>/microcode...
		|-> bios_overrides
		|-> ...

and have this layout extensible from the beginning...

Does that make sense, though?  I'm a bit concerned about having multiple
files named microcode.bin by default; the pathname isn't as sticky as
the filename when people move things around...

Only time will tell. I was simply saying that we should leave ourselves
the door opened, should we need functionality like that in the future.

Ok, I see.

How about the following scheme then:

kernel/x86/<vendor>-microcode.bin
kernel/x86/<vendor>-bios-overrides.blob
...

?

All I'm saying is maybe we should impose some sanity rules now before
people go crazy with this and things get out of hands...

We might name the cpio directory as:

kernel/x86/microcode/GenuineIntel.bin
kernel/x86/microcode/AuthenticAMD.bin
kernel/x86/acpi/...
etc.

This is expendable for the future usage.
 
Plus I will add a doc on the cpio directory, supported directory names and how to add new stuffs in the directory.

Thanks.

I believe that was exactly my original proposal.  I think it makes
sense... most things aren't going to be inherently CPU-specific in this way.

I don't know what Borislav was suggesting with "BIOS overrides", is that
another CPU-specific thing?

Not CPU- but rather platform-specific. It is Thomas Renninger's
mechanism to override BIOS tables.

s/BIOS/ACPI/... Yes, so really it doesn't have any meaningful reason to
live under the CPU vendor.

That's ACPI override. I think the ACPI tables could be put in kernel/x86/acpi/.

kernel/acpi... ACPI is not x86-specific.

Can we drop the vendor-specific text from generic x86 code pls? This
belongs into microcode_intel_* AFAICT.

This function can be made generic by giving the ucode_name down as an
arg, for example, so that other vendors can use it too.

[PATCH 05/11] x86/microcode_intel_lib.c: Early update ucode on Intel's CPU

[Fenghua Yu]

From: Fenghua Yu <fenghua.yu@intel.com>

Define interfaces microcode_sanity_check() and get_matching_microcode(). They
are called both in early boot time and in microcode Intel driver.

Actually,

this one should be merged with 3/11 to kill the build error.

This still doesn't suffice:

ERROR: "get_matching_microcode" [arch/x86/kernel/microcode.ko] undefined!
ERROR: "microcode_sanity_check" [arch/x86/kernel/microcode.ko] undefined!
make[1]: *** [__modpost] Error 1
make: *** [modules] Error 2
make: *** Waiting for unfinished jobs....

.config attached.

And by quickly grepping through it, none of the new options are there:

obj-$(CONFIG_MICROCODE_EARLY)		+= microcode_core_early.o
obj-$(CONFIG_MICROCODE_INTEL_EARLY)	+= microcode_intel_early.o
obj-$(CONFIG_MICROCODE_INTEL_LIB)	+= microcode_intel_lib.o
microcode-y				:= microcode_core.o

which most probably causes the build error. AFAICT, you need to pull up
the arch/x86/Kconfig changes from 11/11 too.

HTH.

[PATCH 06/11] x86/microcode_intel_early.c: Early update ucode on Intel's CPU

[Fenghua Yu]

From: Fenghua Yu <fenghua.yu@intel.com>

Implementation of early update ucode on Intel's CPU.

load_ucode_intel_bsp() scans ucode in initrd image file which is a cpio format
ucode followed by ordinary initrd image file. The binary ucode file is stored
in kernel/x86/microcode/GenuineIntel/microcode.hex in the cpio data. All ucode
patches with the same model as BSP are saved in memory. A matching ucode patch
is updated on BSP.

load_ucode_intel_ap() reads saved ucoded patches and updates ucode on AP.

[PATCH 07/11] x86/head_32.S: Early update ucode in 32-bit

[Fenghua Yu]

From: Fenghua Yu <fenghua.yu@intel.com>

This updates ucode in 32-bit kernel. At this point, there is no paging and no
virtual address yet.

[PATCH 09/11] x86/smpboot.c: Early update ucode on AP

[Fenghua Yu]

From: Fenghua Yu <fenghua.yu@intel.com>

This updates ucode on AP. At this point, BSP should store some valid ucode
patches in memory if it finds the ucode patches in initrd. AP searches the
stored ucode and uploads the ucode.

Fenghua,

I have a few comments, that were triggered by scanning just this patch
(they also assume I remember the kconfig language correctly).

MICROCODE_INTEL_LIB depends on MICROCODE_INTEL_EARLY.
MICROCODE_INTEL_EARLY itself also selects MICROCODE_INTEL_LIB. So can't
this kconfig entry be made to select MICROCODE_INTEL_EARLY instead?

If it can't select MICROCODE_INTEL_EARLY (because of that symbol's
dependency on BLK_DEV_INITRD) it seems this select could be dropped.

MICROCODE_INTEL_EARLY selects this kconfig symbol. Doesn't that mean
that this entry can be simplified to:
    config MICROCODE_EARLY
        bool

> +config MICROCODE_INTEL_LIB
> +	def_bool y

If MICROCODE_INTEL could be made to select MICROCODE_INTEL_EARLY (see
above) it seems this could also be shortened:
    config MICROCODE_INTEL_LIB
        bool

> +config MICROCODE_INTEL_EARLY
> +	bool "Early load microcode"
> +	depends on MICROCODE_INTEL && BLK_DEV_INITRD

If MICROCODE_INTEL could be made to select this kconfig symbol than the
dependency on MICROCODE_INTEL could be dropped. But the dependency on
BLK_DEV_INITRD might make that impossible.

One more thing:

This screams for adding a directory called "microcode" in the kernel
sources and moving all the microcode-related files there. IOW:

arch/x86/kernel/cpu/microcode/core.c
arch/x86/kernel/cpu/microcode/core_early.c
arch/x86/kernel/cpu/microcode/intel.c
arch/x86/kernel/cpu/microcode/amd.c
...

And yes, they should be under "cpu" too.

Not really, but that isn't even Fenghua's fault.

The cpu directory was originally for cpu detection.  The whole kernel/
directory, of course, is a morass that might as well be called "misc".
Some things are legitimately there -- mainly the syscall table and
things that mirror the global kernel/ -- but a ton of stuff doesn't make
any sense there.

Reorganizing the kernel/ directory and promoting cpu up one level would
make that make more sense.  The pci and irq code are examples of things
that could use their own directories.

Of course it isn't - I was simply pointing out that this is something
that should be fixed at some point in time, when someone needs a project

Yep, arch/x86/cpu, should contain all cpu-related stuff.
