David Miller e9003acf36 Ensure TestHarnessRunner doesn't enable UnifiedMemory. 2020-04-25 12:56:37 -04:00
David Miller 0c51baf7a8 Added default Config::UnifiedMemory value to true 2020-04-25 12:49:41 -04:00
David Miller 1589b9a351 Added EnvLoader to frontend binaries, called prior to ArgLoader 2020-04-24 19:53:28 -04:00
David Miller 75ee8f0604 EnvironmentLoader, clean merge 2020-04-24 19:25:57 -04:00
David Miller 5999e7477f Added guard around llvm/IR/IntrinsicsX86.h inclusion, seems to only be needed for version 10?\nMore Investigation needed here.\nChanged Debugger/IMGui.{h,cpp} to IMGui_I so it will build in filesystems that aren't case sensitive.\nAdded CMakeSettings.json that has profiles to build from VisualStudio, using env variables to control system specific options. \n Currently only the WSL is tested (and working). \nRemote should work as well, if correct string for preconfigured remote is in env variable fexremote.\nCross compile (to linux) untested, using sysroot in env variable fexsysroot 2020-04-23 16:12:28 -04:00
Ryan Houdek 780278a7f6 Fixes memory allocation 
4GB virtual memory is too small and causes things to fault.
Previously we were at `1 << 36` but it caused oom issues on devices with
smaller amounts of memory.
This time ensure the the SHM memory is allocated with MEM_NORESERVE so
devices can actually allocate the virtual memory region.

Ryan Houdek 3424326987 Removes accurate-std command line argument 
This is an option that has been removed

Ryan Houdek 5298379fb9 Ensure the ELFLoader doesn't end up in the lower 32bit address space 
We need to reserve that space for EXEC apps and 32bit apps. Hard throw a
warning if any of our mapping space ends up in the lower 32bits.

PIE and potentially a custom dynamic linker can enforce this.

Ryan Houdek 15d5ba6fc1 Adds RootFS search path in ELFLoader

Ryan Houdek 3fd1475d30 Plumbs ELFLoader arguments through the CodeLoader 
This is necessary for execve in the future to keep everything in sync
 2020-03-21 15:19:31 -07:00
Ryan Houdek e5dc72ad69 Fixes the dynamic linker detection 
Fixes #49

Makes it so we no longer have to pass in the ld location to the
ELFLoader application.

Once we switch over to the dynamic linker, the program being executed to
us is no longer a dynamic program.
But the frontend ELF loader also still needs to know that we are
executing the dynamic linker so it can append the linker to the
arguments.

Ryan Houdek 4ea18647ed Make the unit test runner allocate less SHM space 
It doesn't need 64GB of virtual memory, so knock it down to its minimum
virtual memory required

Ryan Houdek a2afd684ae Allows ELF loader to pull in all environment variables 
This will leak some host state which is fine.
Necessary to allow access to things like DISPLAY and XAUTHORITY and
various other bits

Ryan Houdek c0b3a94e4f Fixes up stack space for argv and envp 
These were messy and we were previously losing a page for random
"redzone" which doesn't matter.
We only needed 16bytes more for some additional padding that was needed
for something

 2020-03-06 07:56:17 +02:00
Ryan Houdek ec5f3a6854 Fixes LEA instruction 
LEA changes behaviour based on the ordering of the prefixes on the
instruction

eg:
66 48 8d 3d ffffffff: lea rdi, [rip - 1]
48 66 8d 3d ffffffff: lea di, [rip - 1]

So we need to know the order of a few of the prefixes.
In the future this should probably be switched to a three deep stack to
have the ordering but for now this'll do
