Description: Display fw status registers content
|
||||
|
||||
The ME FW writes its status information into fw status
|
||||
registers for BIOS and OS to monitor fw health.
|
||||
|
||||
The register contains running state, power management
|
||||
state, error codes, and others. The way the registers
|
||||
are decoded depends on PCH or SoC generation.
|
||||
Also number of registers varies between 1 and 6
|
||||
depending on generation.

* QEMU Firmware Configuration bindings for ARM
|
||||
|
||||
QEMU's arm-softmmu and aarch64-softmmu emulation / virtualization targets
|
||||
provide the following Firmware Configuration interface on the "virt" machine
|
||||
type:
|
||||
|
||||
- A write-only, 16-bit wide selector (or control) register,
|
||||
- a read-write, 64-bit wide data register.
|
||||
|
||||
QEMU exposes the control and data register to ARM guests as memory mapped
|
||||
registers; their location is communicated to the guest's UEFI firmware in the
|
||||
DTB that QEMU places at the bottom of the guest's DRAM.
|
||||
|
||||
The guest writes a selector value (a key) to the selector register, and then
|
||||
can read the corresponding data (produced by QEMU) via the data register. If
|
||||
the selected entry is writable, the guest can rewrite it through the data
|
||||
register.
|
||||
|
||||
The selector register takes keys in big endian byte order.
|
||||
|
||||
The data register allows accesses with 8, 16, 32 and 64-bit width (only at
|
||||
offset 0 of the register). Accesses larger than a byte are interpreted as
|
||||
arrays, bundled together only for better performance. The bytes constituting
|
||||
such a word, in increasing address order, correspond to the bytes that would
|
||||
have been transferred by byte-wide accesses in chronological order.
|
||||
|
||||
The interface allows guest firmware to download various parameters and blobs
|
||||
that affect how the firmware works and what tables it installs for the guest
|
||||
OS. For example, boot order of devices, ACPI tables, SMBIOS tables, kernel and
|
||||
initrd images for direct kernel booting, virtual machine UUID, SMP information,
|
||||
virtual NUMA topology, and so on.
|
||||
|
||||
The authoritative registry of the valid selector values and their meanings is
|
||||
the QEMU source code; the structure of the data blobs corresponding to the
|
||||
individual key values is also defined in the QEMU source code.
|
||||
|
||||
The presence of the registers can be verified by selecting the "signature" blob
|
||||
with key 0x0000, and reading four bytes from the data register. The returned
|
||||
signature is "QEMU".
|
||||
|
||||
The outermost protocol (involving the write / read sequences of the control and
|
||||
data registers) is expected to be versioned, and/or described by feature bits.
|
||||
The interface revision / feature bitmap can be retrieved with key 0x0001. The
|
||||
blob to be read from the data register has size 4, and it is to be interpreted
|
||||
as a uint32_t value in little endian byte order. The current value
|
||||
(corresponding to the above outer protocol) is zero.
|
||||
|
||||
The guest kernel is not expected to use these registers (although it is
|
||||
certainly allowed to); the device tree bindings are documented here because
|
||||
this is where device tree bindings reside in general.
|
||||
|
||||
Required properties:
|
||||
|
||||
- compatible: "qemu,fw-cfg-mmio".
|
||||
|
||||
- reg: the MMIO region used by the device.
|
||||
* Bytes 0x0 to 0x7 cover the data register.
|
||||
* Bytes 0x8 to 0x9 cover the selector register.
|
||||
* Further registers may be appended to the region in case of future interface
|
||||
revisions / feature bits.
|
||||
|
||||

|
||||
|

#address-cells = <0x2>;

TX limitations
|
||||
--------------
|
||||
|
||||
Kernel processing usually involves validation of the message received by
|
||||
user-space, then processing its contents. The kernel must assure that
|
||||
userspace is not able to modify the message contents after they have been
|
||||
validated. In order to do so, the message is copied from the ring frame
|
||||
to an allocated buffer if either of these conditions is false:
|
||||
|
||||
- only a single mapping of the ring exists
|
||||
- the file descriptor is not shared between processes
|
||||
|
||||
This means that for threaded programs, the kernel will fall back to copying.
|
||||
As of Jan 2015 the message is always copied from the ring frame to an
|
||||
allocated buffer due to unresolved security concerns.
|
||||
See commit 4682a0358639b29cf ("netlink: Always copy on mmap TX.").

* See note at ARMv7 ARM B1.14.4 (TL;DR: S/W ops are not easily virtualized).
|

*
|

* Main problems:
|
||||
* - S/W ops are local to a CPU (not broadcast)
|
||||
* - We have line migration behind our back (speculation)
|
||||
* - System caches don't support S/W at all (damn!)
|
||||
*
|
||||
* In the face of the above, the best we can do is to try and convert
|
||||
* S/W ops to VA ops. Because the guest is not allowed to infer the
|
||||
* S/W to PA mapping, it can only use S/W to nuke the whole cache,
|
||||
* which is a rather good thing for us.
|
||||
*
|
||||
* Also, it is only used when turning caches on/off ("The expected
|
||||
* usage of the cache maintenance instructions that operate by set/way
|
||||
* is associated with the cache maintenance instructions associated
|
||||
* with the powerdown and powerup of caches, if this is required by
|
||||
* the implementation.").
|
||||
*
|
||||
* We use the following policy:
|
||||
*
|
||||
* - If we trap a S/W operation, we enable VM trapping to detect
|
||||
* caches being turned on/off, and do a full clean.
|
||||
*
|
||||
* - We flush the caches on both caches being turned on and off.
|
||||
*
|

* - Once the caches are enabled, we stop trapping VM ops.
