Bryan O'Donoghue 28a375df16 x86/intel/quark: Add Isolated Memory Regions for Quark X1000 
Intel's Quark X1000 SoC contains a set of registers called
Isolated Memory Regions. IMRs are accessed over the IOSF mailbox
interface. IMRs are areas carved out of memory that define
read/write access rights to the various system agents within the
Quark system. For a given agent in the system it is possible to
specify if that agent may read or write an area of memory
defined by an IMR with a granularity of 1 KiB.

Quark_SecureBootPRM_330234_001.pdf section 4.5 details the
concept of IMRs quark-x1000-datasheet.pdf section 12.7.4 details
the implementation of IMRs in silicon.

eSRAM flush, CPU Snoop write-only, CPU SMM Mode, CPU non-SMM
mode, RMU and PCIe Virtual Channels (VC0 and VC1) can have
individual read/write access masks applied to them for a given
memory region in Quark X1000. This enables IMRs to treat each
memory transaction type listed above on an individual basis and
to filter appropriately based on the IMR access mask for the
memory region. Quark supports eight IMRs.

Since all of the DMA capable SoC components in the X1000 are
mapped to VC0 it is possible to define sections of memory as
invalid for DMA write operations originating from Ethernet, USB,
SD and any other DMA capable south-cluster component on VC0.
Similarly it is possible to mark kernel memory as non-SMM mode
read/write only or to mark BIOS runtime memory as SMM mode
accessible only depending on the particular memory footprint on
a given system.

On an IMR violation Quark SoC X1000 systems are configured to
reset the system, so ensuring that the IMR memory map is
consistent with the EFI provided memory map is critical to
ensure no IMR violations reset the system.

The API for accessing IMRs is based on MTRR code but doesn't
provide a /proc or /sys interface to manipulate IMRs. Defining
the size and extent of IMRs is exclusively the domain of
in-kernel code.

Quark firmware sets up a series of locked IMRs around pieces of
memory that firmware owns such as ACPI runtime data. During boot
a series of unlocked IMRs are placed around items in memory to
guarantee no DMA modification of those items can take place.
Grub also places an unlocked IMR around the kernel boot params
data structure and compressed kernel image. It is necessary for
the kernel to tear down all unlocked IMRs in order to ensure
that the kernel's view of memory passed via the EFI memory map
is consistent with the IMR memory map. Without tearing down all
unlocked IMRs on boot transitory IMRs such as those used to
protect the compressed kernel image will cause IMR violations and system reboots.

The IMR init code tears down all unlocked IMRs and sets a
protective IMR around the kernel .text and .rodata as one
contiguous block. This sanitizes the IMR memory map with respect
to the EFI memory map and protects the read-only portions of the
kernel from unwarranted DMA access.

output switching, ThinkLight control, UltraBay eject and more.
For more information about this driver see
<file:Documentation/laptops/thinkpad-acpi.txt> and
<http://ibm-acpi.sf.net/> .
This driver was formerly known as ibm-acpi.
Extra functionality will be available if the rfkill (CONFIG_RFKILL)
and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
Note that if you want ThinkPad-ACPI to be built-in instead of
modular, ALSA and rfkill will also have to be built-in.
If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
config THINKPAD_ACPI_ALSA_SUPPORT
bool "Console audio control ALSA interface"
depends on THINKPAD_ACPI
depends on SND
depends on SND = y || THINKPAD_ACPI = SND
default y
---help---
Enables monitoring of the built-in console audio output control
(headphone and speakers), which is operated by the mute and (in
some ThinkPad models) volume hotkeys.
If this option is enabled, ThinkPad-ACPI will export an ALSA card
with a single read-only mixer control, which should be used for
on-screen-display feedback purposes by the Desktop Environment.
Optionally, the driver will also allow software control (the
ALSA mixer will be made read-write). Please refer to the driver
documentation for details.
All IBM models have both volume and mute control. Newer Lenovo
models only have mute control (the volume hotkeys are just normal
keys and volume control is done through the main HDA mixer).
config THINKPAD_ACPI_DEBUGFACILITIES
bool "Maintainer debug facilities"
depends on THINKPAD_ACPI

---help---
Enables extra stuff in the thinkpad-acpi which is completely useless
for normal use. Read the driver source to find out what it does.
Say N here, unless you were told by a kernel maintainer to do
otherwise.
config THINKPAD_ACPI_DEBUG
bool "Verbose debug mode"
depends on THINKPAD_ACPI

---help---
Enables extra debugging information, at the expense of a slightly
increase in driver size.
If you are not sure, say N here.
config THINKPAD_ACPI_UNSAFE_LEDS
bool "Allow control of important LEDs (unsafe)"
depends on THINKPAD_ACPI
default n
---help---
Overriding LED state on ThinkPads can mask important
firmware alerts (like critical battery condition), or misled
the user into damaging the hardware (undocking or ejecting
the bay while buses are still active), etc.
LED control on the ThinkPad is write-only (with very few
exceptions on very ancient models), which makes it
impossible to know beforehand if important information will
be lost when one changes LED state.
Users that know what they are doing can enable this option
and the driver will allow control of every LED, including
the ones on the dock stations.
Never enable this option on a distribution kernel.
Say N here, unless you are building a kernel for your own
use, and need to control the important firmware LEDs.
config THINKPAD_ACPI_VIDEO
bool "Video output control support"
depends on THINKPAD_ACPI
default y
---help---
Allows the thinkpad_acpi driver to provide an interface to control
the various video output ports.
This feature often won't work well, depending on ThinkPad model,
display state, video output devices in use, whether there is a X
server running, phase of the moon, and the current mood of
Schroedinger's cat. If you can use X.org's RandR to control
your ThinkPad's video output ports instead of this feature,
don't think twice: do it and say N here to save memory and avoid
bad interactions with X.org.
NOTE: access to this feature is limited to processes with the
CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
where it interacts badly with X.org.
If you are not sure, say Y here but do try to check if you could
be using X.org RandR instead.
config THINKPAD_ACPI_HOTKEY_POLL
bool "Support NVRAM polling for hot keys"
depends on THINKPAD_ACPI
default y
---help---
Some thinkpad models benefit from NVRAM polling to detect a few of
the hot key press events. If you know your ThinkPad model does not
need to do NVRAM polling to support any of the hot keys you use,
unselecting this option will save about 1kB of memory.
ThinkPads T40 and newer, R52 and newer, and X31 and newer are
unlikely to need NVRAM polling in their latest BIOS versions.
NVRAM polling can detect at most the following keys: ThinkPad/Access
IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
If you are not sure, say Y here. The driver enables polling only if
it is strictly necessary to do so.
config SENSORS_HDAPS
tristate "Thinkpad Hard Drive Active Protection System (hdaps)"

help
This driver provides support for the IBM Hard Drive Active Protection
System (hdaps), which provides an accelerometer and other misc. data.
ThinkPads starting with the R50, T41, and X40 are supported. The
accelerometer data is readable via sysfs.
This driver also provides an absolute input class device, allowing
the laptop to act as a pinball machine-esque joystick.
If your ThinkPad is not recognized by the driver, please update to latest
BIOS. This is especially the case for some R52 ThinkPads.
Say Y here if you have an applicable laptop and want to experience
the awesome power of hdaps.

help
This driver adds support for the ACPI-WMI (Windows Management
Instrumentation) mapper device (PNP0C14) found on some systems.
ACPI-WMI is a proprietary extension to ACPI to expose parts of the
ACPI firmware to userspace - this is done through various vendor
defined methods and data blocks in a PNP0C14 device, which are then
made available for userspace to call.
The implementation of this in Linux currently only exposes this to
other kernel space drivers.
This driver is a required dependency to build the firmware specific

This driver adds support for access to certain system settings
on "legacy free" Toshiba laptops. These laptops can be recognized by
their lack of a BIOS setup menu and APM support.
On these machines, all system configuration is handled through the
ACPI. This driver is required for access to controls not covered
by the general ACPI drivers, such as LCD brightness, video output,
etc.
This driver differs from the non-ACPI Toshiba laptop driver (located
under "Processor type and features") in several aspects.
Configuration is accessed by reading and writing text files in the
/proc tree instead of by program interface to /dev. Furthermore, no
power management functions are exposed, as those are handled by the
general ACPI drivers.

This option provides a means to manipulate Isolated Memory Regions.
IMRs are a set of registers that define read and write access masks
to prohibit certain system agents from accessing memory with 1 KiB
granularity.
IMRs make it possible to control read/write access to an address
by hardware agents inside the SoC. Read and write masks can be
defined for:
- eSRAM flush
- Dirty CPU snoop (write only)
- RMU access
- PCI Virtual Channel 0/Virtual Channel 1
