These VHE flags are not needed anymore.
They were used to trap EL2 access to VHE only registers (like CPACR_EL12)
when VHE was disabled (hcr.e2h = 0)
With the new faulting logic, we can just introduce VHE specific
callbacks checking for the hcr.e2h bitfield and returning an undefined
instruction if VHE is disabled.
In this way we don't have to add VHE only bits to every system register

This patch is adding per-EL read/write callbacks to the MiscRegLUTEntry
class. The goal is to merge access permission and trapping logic into
these unified callbacks
As of now the default callbacks are simply reimplementing the access
permission code, checking for MiscRegLUTEntry flags. This is the default
behaviour for all registers.
Trapping code (from MiscRegOp64::trap) will be moved with a later patch

The iss field is only used when the MSR/MRS instruction
gets trapped. Rather than generating it at decode time,
we generate the value within the trap method instead
This avoids the confusion of having a MSR/MRS register
instruction storing an immediate field
Later patches will change this even further by generating the
iss field on the fly ONLY if the instruction gets trapped

Now that we have a pointer to the actual RegClass the RegId is
associated with, we can use it's regName method to pretty print the
RegId for us. This gets rid of the redundant print method for RegId.
Also, replace the default register printing method with the
implementation in the << operator, which is more descriptive.

This commit added two paramaters in the set_se_binary_workload to pass
input parameters for the binary.
The "arguments" object allows users to pass in arugments in a list.
The "stdin_file" object allows users to pass in input file as a
Resource.
This commit also created a local variable "binary_path" to save the
return object of "binary.get_local_path()".
Note:
These new parameters were tested and passed in 4 cases:
1. only passing in (Resource/CustomResource) binary
2. passing in (CustomResource) binary and input_file
3. passing in (CustomResource) binary and argument(no input file
directory included)
4. passing in (CustomResource) binary and argument(with input file
directory included)

This option doesn't work and triggers a warning by Linux when booting.
To make it work, we need a chosen node containing an `stdout-path`
property in the FDT which currently doesn't exist.
I tried to create via a couple of approaches it but encountered multiple
issues:
1. One can set `stdout-path` to the complete path of the tty device, but
such path is impossible to get programmatically (unless it's
hardcoded).
2. One can set `stdout-path` as a reference to a label. While labels are
possible to generate easily, reference to labels cannot be generated
with the current FDT library.
So just remove this option for the time being.

First, this CL modifies the implementation of WFI so it actually put the
calling CPU into sleep.
This CL also adds an id in the IRQ table to represent NMI. This is
because the wakeup path is only implemented on cpu's postInterrupt
function, and it expects an int_num.
We still keep the MISCREG for nmie and nmip instead of merging them into
other ip/ie as that will give the user ability to get/set the nmi
status, which is pretty dangerous.

combination with the number of banks, it determines the number of

not directly affect the L1 latency as the name implies. Instead,
the mandatory_queue_latency does this.

Add a pre-precommit configuration that can be used to run a series of
automated tests in CI. This configuration currently enforces Black
style on Python files and checks for other common errors (incorrect
json, mixed line endings etc.).
The CI system runs pre-commit using the following command:
pre-commit run --from-ref HEAD~ --to-ref HEAD
Users can install pre-commit hooks in their git repositories using the
following command:
pre-commit install
Note that our scons scripts automatically install a simple style
checker as a pre-commit hooks already. If the pre-commit tool is
installed after the existing hook, the existing hook will be kept and
called automatically.
The current pre-commit configuration doesn't currently doesn't run the
C++ style checker automatically. This feature could easily be added in
the future by adding the following to the pre-commit file:
- repo: local
hooks:
- id: style-checker
name: Check C++ coding style
language: python
entry: util/style.py -f
The main reason this isn't already in the configuration is that it is
expected that the style checker will have some false positives since
style checks will be enforced on the entire file rather than the lines
changed in a commit.
