In the field there are different hardware revisions and some
of them have problems with UDMA as a resistor is missing. We can
detect this situation in coreboot and e.g. the linux kernel
can take this knowledge and disable UDMA.

Add code to do the following for the VIA Nano CPUs
- Update microcode
- Set maximum frequency
- Initialize power states
- Set up cache
Attempting to change the voltage or frequency of the CPU without
applying the microcode update will hang the CPU, so we only do
transitions if we can verify the microcode has been updated.
The microcode is updated directly from CBFS. No microcode is
included in ramstage. The microcode is not included in this
commit.
To get the microcode, run bios_extract on the manufacturer supplied
BIOS, and look for the file marked "P6 Microcode". Include this
file in CBFS.
You can have the build system include this file automatically by
selecting Expert Mode, then look under
'Chipset' -> 'Include CPU microcode in CBFS' ->
Include external microcode file (check)
'Path and filename of CPU microcode' should contain the location of
the microcode file previously extracted.

This patch aims to improve the microcode in CBFS handling that was
brought by the last patches from Stefan and the Chromium team.
Choices in Kconfig
- 1) Generate microcode from tree (default)
- 2) Include external microcode file
- 3) Do not put microcode in CBFS
The idea is to give the user full control over including non-free
blobs in the final ROM image.
MICROCODE_INCLUDE_PATH Kconfig variable is eliminated. Microcode
is handled by a special class, cpu_microcode, as such:
cpu_microcode-y += microcode_file.c
MICROCODE_IN_CBFS should, in the future, be eliminated. Right now it is
needed by intel microcode updating. Once all intel cpus are converted to
cbfs updating, this variable can go away.
These files are then compiled and assembled into a binary CBFS file.
The advantage of doing it this way versus the current method is that
1) The rule is CPU-agnostic
2) Gives user more control over if and how to include microcode blobs
3) The rules for building the microcode binary are kept in
src/cpu/Makefile.inc, and thus would not clobber the other makefiles,
which are already overloaded and very difficult to navigate.

Unfortunately the method of synchronizing rdtsc is different

Hence, use the correct lfence/mfence instructions (for CPUs that

Some mainboards have really nice capabilities for posting, beyond

change defines a weak symbol (mainboard_post) that can be overridden
by a real mainboard_post function.
If, for example, you'd like to do something fancy before the payload starts,
you can add this to mainboard.c:
void mainboard_post(u8 value)
{
switch(value){
case POST_TIME_TO_PARTY: some_fancy_lights();
break;
}
}
Maybe the post function should be an entry in the device. We're beginning to over-use
weak symbols.

We thought about two ways to do this change. The way we decided to try
was to
1. drop all ops from devices in romstage
2. constify all devices in romstage (make them read-only) so we can
compile static.c into romstage
3. the device tree "devices" can be used to read configuration from
the device tree (and nothing else, really)
4. the device tree devices are accessed through struct device * in
romstage only. device_t stays the typedef to int in romstage
5. Use the same static.c file in ramstage and romstage
We declare structs as follows:
ROMSTAGE_CONST struct bus dev_root_links[];
ROMSTAGE_CONST is const in romstage and empty in ramstage; This
forces all of the device tree into the text area.
So a struct looks like this:
static ROMSTAGE_CONST struct device _dev21 = {
#ifndef __PRE_RAM__
.ops = 0,
#endif
.bus = &_dev7_links[0],
.path = {.type=DEVICE_PATH_PCI,{.pci={ .devfn = PCI_DEVFN(0x1c,3)}}},
.enabled = 0,
.on_mainboard = 1,
.subsystem_vendor = 0x1ae0,

With SandyBridge northbridge code, uma_memory_size was reset to

Keep the behaviour that way, mmio_resource() has a prerequisuite that

The result is not optimal setup in the number of used MTRRs, but
continue with this approach until MTRR algorithm is improved.

Commit 2d42b34003 changed the
variable MTRR setup and removed compensation of uma_memory_size in
the cacheable memory resources.
Since the cacheable region size was no longer divisible by a large
power of 2, like 256 MB, this caused excessive use of MTRRs.
As first symptoms, slow boot with grub and poor user response.
As a solution, register the actual top of low ram with ram_resource(),
and do not subtract the UMA/TSEG regions from it.
TSEG may require further work as the original did not appear exactly
right to begin with. To have UMA as un-cacheable, use uma_resource().

Also add a method to notify the thermalzones of a change

the thermalzone to read a different sensor.
Then, use a kernel driver that contains the following:
/* Adjust temperature sensor id to 2 */
union acpi_object param;
struct acpi_object_list input;
param.type = ACPI_TYPE_INTEGER
param.integer.value = 2

acpi_evaluate_object(NULL, "\\TMPU", &input, NULL);
And ensure that the temperature sensor that is being

In order to support the GSMI interface the SMI handler needs
to find and use the state save area from the same CPU that
initiated the SMI. In this case it is a synchronous SMI
resulting form an IO write to port 0xB2.
To find the right CPU state save area iterate over the region
until the "IO Misc Info" field reports the expected value and
then proceed to use that state save area.
This is needed because the coreboot SMI handler only executes on
one core, and that core is non-deterministic. It is likely that
the core executing the C SMM handler is not the same one that
actually did the IO write to 0xB2 and generated the SMI.
The GSMI parameter buffer is passed as a pointer to EBX in the
tate save area, and the GSMI command is extracted from EAX before
it is used as the return value.
This interface is tested by enabling CONFIG_GOOGLE_GSMI in the
kernel and generating events and verifying that they end up
in the event log.

The linux kernel contains an SMI driver that was written by
me (Duncan) and upstreamed a couple years ago called GSMI.
This driver will format a parameter buffer and pass pointers
to this parameter buffer to the SMI handler. It uses this to
generate events for kernel shutdown reasons: Clean, Panic, Oops,
etc.
This function expects to be passed pointers into the SMM state
save area that correspond to the prameter buffer and the return
code, which are typically EAX and EBX.
The format of the parameter buffer is defined in the kernel
driver so we implement the same interface here in order to be
compatible.
GSMI_CMD_HANDSHAKE: this is an early call that it does to try
and detect what kind of BIOS is running.
GSMI_CMD_SET_EVENT_LOG: this contains a parameter buffer that
has event type and data. The kernel-specific events are
translated here and raw events are passed through as well which
allows any run-time event to be added for testing.
GSMI_CMD_CLEAR_EVENT_LOG: this command clears the event log.
First the gsmi driver must be enabled in the kernel with
CONFIG_GOOGLE_GSMI and then events can be added via sysfs
and events are automatically generated for various kernel
shutdown reasons.
These can be seen in the event log as the 'Kernel Event' type:

was never upstreamed and removed from our tree, u-boot was changed to
get the information it needs from the coreboot table alone. However,
in the process of this change only the vboot shared data structure was
passed on by coreboot, so when u-boot tried to update the ChromeOS
specific ACPI entries, it would accidently overwrite the vboot data.
This patch passes on the ChromeOS specific ACPI data structure instead
of the vboot shared data. Another change to u-boot will teach it how
to get to the vboot shared data from there.

CPUs with configurable TDP will run the TSC at the max non-turbo

TDP is desired. To deal with this we set the flex ratio to the
nominal TDP ratio early in the boot and then configure the Soft
Reset Data registers so the PCH can tell the CPU what frequency
to run at after a reset.
This is done very early in the bootblock because it is necessary
to reset the system after setting a flex ratio.
The end result is that the TSC will now increment at the max
non-turbo frequency for the nominal TDP.

This is used by the SPI driver and ELOG.
It requires SMM TSEG and a _heap/_eheap region defined in the
linker script. The first time malloc is called in SMM the
start and end pointers to the heap region will be relocated
for the TSEG region.
Enable SPI flash and ELOG in SMM and successfully
allocate memory. The allocated addresses are verified
to be sure they are within the TSEG heap region:
smm.elf:00014000 B _eheap
smm.elf:00010000 B _heap
TSEG base is 0xad000000

This is based around the SMBIOS event log specification but
expanded with OEM event types to support more specific and
relevant system events.
It requires flash storage and a minimum 4K block (or flash block
size) that should be allocated in the FMAP.
A copy of the event log is maintained in memory for convenience
and speed and the in-memory copy is written to flash at specific
points.
The log is automatically shunk when it reaches a configurable
full threshold in order to not get stuck with a full log that
needs OS help to clear.
ELOG implements the specification published here:
http://code.google.com/p/firmware-event-log/wiki/FirmwareEventLogDesign
And is similar to what we use in other firmware at Google.
This implementation does not support double-buffered flash
regions. This is done because speed is valued over the log
reliability and it keeps the code simpler for the first version.
This is a large commit and by itself it just provides a new
driver that is made available to coreboot. Without additional
patches it is not very useful, but the end result is an event
log that will contain entries like this:
171 | 2012-06-23 16:02:55 | System boot | 285
172 | 2012-06-23 16:02:55 | EC Event | Power Button

In order to support SPI and ELOG drivers the SMM region
needs to be able to be larger than the previous allocation
below 0x7400. Now that we have support for 4M TSEG we do
not need to live in this region.
This change adds a 16KB heap region abofe the save state area
at TSEG+64KB and moves the C handler above this.
The heap region is then available for malloc and the C handler
can grow to support flash and event log features.
While updating the memory map comment in assembly stub I also
added a pause instruction to the cpu spin lock as this was
added to the C code in latest upstream rebase.

Ivybridge B0+ CPUs are capable of supporting multiple TDP levels.
This complicates the default case because now the registers that
were reporting max non-turbo ratio are reporting that value for
the highest possible TDP level.
For now this change just forces everything to use the Nominal TDP
values instead of the higher (or lower) levels.
- When building P-state tables, determine the P[1] (max non turbo)
ratio based on the Nominal ratio if available.
- Set the turbo activation ratio to the Nominal max ratio.
- Mirror the power level settings in new MCHBAR register after
they are written, which happens after BIOS_RESET_CPL is set.
- Set the current ratio to Nominal ratio at boot.
1) Verify that P-state table is generated properly with
P[0]=1801MHz (ratio 0x1C) and P[1]=1800MHz (ratio 0x12)
PSS: 1801MHz power 17000 control 0x1c00 status 0x1c00
PSS: 1800MHz power 17000 control 0x1200 status 0x1200
2) Verify power limits in MCHBAR match PKG_POWER_LIMIT:
> rdmsr 0 0x610
0x800080aa00dc8088
> mmio_read32 0xfed159a4
0x000080aa
> mmio_read32 0xfed159a0
0x00dc8088
3) Verify turbo activation ratio is set to nominal ratio:
> rdmsr 0 0x64c
0x0000000000000012
4) Check that proper ratio was set at boot on one core only:
> grep 'frequency set to' /sys/firmware/log
model_x06ax: frequency set to 1800
model_x06ax: frequency set to 1800
model_x06ax: frequency set to 1800

Previous patches implemented stack overflow checking for the APs.
This patch builds on the BSP stack poisoning patch to implement
stack overflow checking for the BSP, and also prints out maximum
stack usage. It reveals that our 32K stack is ridiculously oversized,
especially now that the lzma decoder doesn't use a giant 16K on-stack
array.
Break the stack checking out into a separate function, which
we will later use for the APs.
CPU0: stack from 00180000 to 00188000:Lowest stack address 00187ad8
To test failure, change the DEADBEEF stack poison value in c_start.S
to something else. Then we should get an error like this:
Stack overrun on BSP.Increase stack from current 32768 bytes
CPU0: stack from 00180000 to 00188000:Lowest stack address 00180000
Separate the act of loading from the act of starting the payload. This
allows us better error management and reporting of stack use. Now we
see:
CPU0: stack from 00180000 to 00188000:Lowest stack address 00187ad8
Tested for both success and failure on Link. At the same time, feel free
to carefully check my manipulation of _estack.

There are several reasons for this:
1. It's a core setting, not a platform setting, which is bizarre. But,
we disable vmx via an SMI, and that only happens on core 0.
Hence, the code did not correctly make the same settings on all cores-
one had them disabled, the others were in an unknown state.
When (e.g.) kvm started on a vmx-enabled core, then moved to a
vmx-disabled core, the processor would reset *very* quickly.
Changing this would be messy.

Northbridge code incorrectly adjusted the last cacheable memory
resource to accomodate room for UMA framebuffer. If system had
4GB or more memory that last resource is not below 4GB and not
the one where UMA is located.
There are three consequences:
The last entry in coreboot memory table is reduced by uma_memory_size.
Due the incorrect code in northbridge code state.tomk,
end of last resource below 4GB, had not been adjusted.
Incrementing that by uma_memory_size diverts a region
possibly claimed for MMIO to RAM, as TOP_MEM is written.
Since the UMA framebuffer did not have IORESOURCE_CACHEABLE,
it was ignored from the MTRR setup and not set uncacheable.
The setting of TOP_MEM and TOP_MEM2, as well as all the MTRRs,
should be copied from BSP to all APs instead of deriving the data
separately for each Logical CPU.

The ioapic_irq directive can be used in pci and pci_domain

of ramstage copy_and_run are only partly set cacheable.
It appears variable MTRR setting for XIP cache is left enabled on
model_106cx code, where it should have extended to cover all of Flash.

A diff from model_6fx to model_106cx suggests there is little
CORE2 specific code that was once considered useful to have.
In its current status however, sockets supporting model_6fx use
model_6ex CAR init, so that specific code is actually
never used.

Default CPU_ADDR_BITS is 36.
For Atom (model_106cx) use 32. This model is known to
fail execution-in-place (XIP) with the default 36.
Pentium M should use 32, but doesn't even with this patch.
Some Xeon and CORE(2) models should use 38 or 40.

The error message from romstage is annoying and misleading:
"Do not use global variables in romstage"
Because it can occur even when global variables are not used
in some circumstances, but also because it gives you only a rough
idea where to look. This change sucks but sucks less. We still don't
know which file the problem is in but at least we know if it is data
or bss.
Replace the error message with something that provides more information
and less guessing on the part of the script:
".bss is non-zero size in romstage which is not allowed -- global variable?"
or
".data is non-zero size in romstage which is not allowed -- global variable?"
To test: build coreboot as normal. It builds.
Add
char d[32];
to romstage.c and get the first error message; add
int x = 32;
to romstage.c and get the second.

The current code for initializing AP cpus has several shortcomings:
- it assumes APIC IDs are sequential
- it uses only the BSP for determining the AP count, which is bad if
there's more than one physical CPU, and CPUs are of different type
Note that the new code call cpu->ops->init() in parallel, and therefore
some CPU code needs to be changed to address that. One example are old
Intel HT enabled CPUs which can't do microcode update in parallel.

Early HT-enabled CPUs do not serialize microcode updates within a core.
Solve this by running microcode updates on the thread with the smallest
lapic ID of a core only.
Also set MTRRs once per core only.
