for a reader to understand what those sequences of number and boolean

4 years agobase: Use a int to store fgetc return value
Giacomo Travaglini [Fri, 14 Feb 2020 10:24:01 +0000 (10:24 +0000)]
base: Use a int to store fgetc return value

The stdio fgetc returns the character read as an unsigned char cast to
an int.
The reason why it gets casted from unsigned char to int is because EOF
is defined as a negative value (usually -1).

At the moment in the atomicio.test we store the int in a char.

However the C standard states that the sign of a char is implementation
specific. This makes the test non portable: an architecture/ABI which
which is considering a char as a unsigned char won't compile since a
unsigned value will always be != -1 (EOF).

This is the error message you would get on a aarch64 host /w gcc/5.4.0

4 years agox86: Handle m5 op accesses directly in the mmapped IPR handlers.

x86: Handle m5 op accesses directly in the mmapped IPR handlers.

The common handlers only handle the m5ops, and it takes more plumbing
to get to them than to just handle the m5ops directly from x86.

Gabe Black [Wed, 29 Jan 2020 11:22:05 +0000 (03:22 -0800)]
sim,cpu: Move the call to initCPU into System.

The call to initCPU was moved into initState in the base CPU class
since it should only really be called when starting a simulation
fresh. Otherwise checkpointed state will be loaded over the state of
the CPU anyway, so there's no reason to set up anything else.

Unfortunately that made it possible for the System level initialization
and the CPU initialization to happen out of order, effectively letting
initCPU clobber the state the System might have set up to prepare for
executing a kernel for instance.

To work around that issue, the call was moved to init which would
necessarily happen before initState, restoring the original ordering.

This change moves the change *back* into initState, but of the System
class instead of the CPU class. This makes it possible to guarantee
that OS initialization happens after initCPU since that's also done
by System subclasses, and they control when they call initCPU of the
base class.

This also slightly simmplifies when initCPU is called since we
shouldn't need to check whether a context is switched out or not. If
it's registered with the System object, then it should be in a
currently swapped in CPU.

This also puts the initCPU and startupCPU calls right next to each
other. A future change will take advantage of that and merge the
calls together.

Also, because there are already ISA specific subclasses of System
which already have specialized versions of initState, we should be
able to move the code in initCPU and startupCPU directly into those
subclasses. That will give those subclasses more flexibilty if, for
instance, they want all CPUs to start running in the BIOS like they
would on a real system, or if they want only the BSP to be active
as if the BIOS had already paused the APs before passing control to
a bootloader or OS.

This will also remove another two TheISA:: style functions, reducing
the number of global dependencies on a single ISA.

4 years agoconfigs: allow fs.py and fs_bigLITTLE.py to work without M5_PATH
Ciro Santilli [Tue, 29 Oct 2019 14:18:24 +0000 (14:18 +0000)]
configs: allow fs.py and fs_bigLITTLE.py to work without M5_PATH

The requirement to have an environment variable exported to run a program
is not common, and many new users trip up on it.

Before this commit, M5_PATH was a requirement to run those scripts, or
else simulation would fail with:

IOError: Can't find a path to system files.

After this patch, as long as users indicate all required files with
command line options, M5_PATH is not needed.

This patch changes the M5_PATH semantics slightly to more closely match
PATH and so be more intuitive to users: after this commit, if the
given path contains a slash /, then the path is not searched for inside
M5_PATH, which is exactly how PATH works. Users can then select images
in the CWD with a leading ./ just as done for executables.

This is backwards incompatible if users were already specifying their paths
as ./, but this interface feels saner, because otherwise writing on the CLI
e.g.:

--disk-image path/to/my.disk

would previously fail to find the disk, even if it existed, which is very
counter-intuitive. The following will still fail however:

--disk-image my.disk

which is not ideal, but for now is a comprise between backwards
compatibility of having an M5_PATH and what users expect from CLI
interfaces.

4 years agoconfigs: fs.py can take multiple disk images on most ISAs
Ciro Santilli [Tue, 29 Oct 2019 16:00:24 +0000 (16:00 +0000)]
configs: fs.py can take multiple disk images on most ISAs

All ISAs except SPARC can now take multiple disk images by passing
the --disk-image option multiple times.

Before this patch, several ISAs automatically mounted a secondary disk
called "linux-bigswap2.img", which had to be in M5_PATH even if the end
user did not want more than one disk. This was the case for for example
for X86 but not ARM.

This change was done to:

* allow ARM to have a second disk image in fs.py, which was not possible,
  and allow other ISAs like X86 and ARM to take any number of disk images

* provide a simpler, more intuitive CLI interface that does not require
  magic disk images to be present in M5_PATH to work for ISAs such as X86.

  Linux does not need that secondary image to boot correctly, so it is
  more friendly to support a minimal setup that requires the least amount
  of binaries to boot, and let supply the second image manually only if
  they need it.

* make fs.py --disk-image work more similarly across all ISAs

SPARC was left with a single disk only because its setup was a bit more
complex and would require further testing.

sim: Add a GuestABI mechanism to allocate space for a return value.

Some ABIs (including 32 bit ARM, 64 bit x86) allocate their argument
registers differently depending on their return value. For instance,
if the value needs to be returned in memory because it's too big,
the caller could pass a pointer to where the result should be stored
when the function returns. This pointer acts like an invisible first
argument, offsetting where all the normal arguments actually live.

This change adds a mechanism to handle that case. The Result templates
can now declare an allocate() static method which is given a
ThreadContext *, and a reference to the Position object. It can perform
any adjustment it needs to before the normal argument extraction
starts.
