MSR <pstatefield>, #imm is used for setting a PSTATE field using an immediate. Current implementation has the following flaws: * There is no base MSR immediate definition: all the existing PSTATE fields have a different class definition * Those implementation make use of a generic data64 base class which results in a wrong disassembly (pstate register is printed as an integer register). This patch is fixing this by defining a new base class (MiscRegImmOp64) and new related templates. In this way, we aim to ease addition of new PSTATE fields (in ARMv8.x) Change-Id: I71b630ff32abe1b105bbb3ab5781c6589b67d419 Signed-off-by: Giacomo Travaglini <giacomo.travaglini@arm.com> Reviewed-by: Andreas Sandberg <andreas.sandberg@arm.com> Reviewed-on: https://gem5-review.googlesource.com/c/public/gem5/+/19728 Maintainer: Andreas Sandberg <andreas.sandberg@arm.com> Tested-by: kokoro <noreply+kokoro@google.com>

2019-06-26arch, arm: Update miscRegs in getTEAnouk Van Laer
Normally, a translation will start via translateTiming/functional which will check if the miscRegs have been updated and if so, will update the TLB state accordingly. However, in a 2 stage system, if there is a hit in stage 1, the resulting IPA will be sent to the S2-TLB for translation via a getTE() function call (via the stage2_lookup object). This will cause the state of the S2-TLB to be out of sync.

2019-05-30arch, base, cpu, gpu, sim: Merge getMemProxy and getVirtProxy.Gabe Black
These two functions were performing the same function but had two different names for historical reasons. This change merges them together, keeping the getVirtProxy name to be consistent with the getPhysProxy method used to get a non-translating proxy port.

Al(most) all of the interesting differences between the two classes have been removed. There are some control methods which are still specific to each type which may require treating them as their true type, but most code that consumes them doesn't need to worry about which is which.

2019-05-30arch, base, sim: Replace Copy(String)?(In|Out) with equivalent code.Gabe Black
This expands those functions into code which extracts the virt proxy and then uses the appropriate method on it. This has two benefits. First, the Copy* functions where mostly redundant wrappers around the methods the proxy port already had. Second, using them forced a particular port which might not actually be what the user wanted.

2019-05-29sim-se: add a release parameter to Process.pyCiro Santilli
Set the default release to that single value for all ISAs. glibc has checks for the kernel version based on uname, and refuses to start any syscall emulation programs if those checks don't pass with error: FATAL: kernel too old The ideal solution to this problem is to actually implement all missing system calls for the required kernel version and bumping the release accordingly. However, it is very hard to implement all missing syscalls and verify compliance. Previously, we have simply bumped the version manually from time to time when major glibc versions started breaking. This commit alleviates the problem in two ways. Firstly, having a single kernel version for all versions means that it is easier to bump all versions at once. Secondly, it makes it is possible to set the release with a parameter, which in turn can be set from the command line with: se.py --param 'system.cpu[:].workload[:].release = "4.18.0"' Change-Id: I9e3c31073bfe68735f7b0775c8e299aa62b98222 Reviewed-on: https://gem5-review.googlesource.com/c/public/gem5/+/17849 Maintainer: Brandon Potter <Brandon.Potter@amd.com> Reviewed-by: Jason Lowe-Power <jason@lowepower.com> Tested-by: kokoro <noreply+kokoro@google.com>

2019-05-29arm, mem: Move the SecurePortProxy subclass into it's own file.Gabe Black
The idea of a "secure" memory area/access is specific to ARM and shouldn't be in the common mem directory, although it's built in to the generic memory protocol at this point. Regardless, it should minimially be in its own file like the virtual and physical port proxy classes are.
