statedata.h gets included from arch/machine.h, and statedata
does not require any of the machine.h definitions.
As a result of removing this various other, previously missing,
includes need to be added
benchmark_track.h does not depend upon anything in debug.h and
so it does not need to include it. Once this include is removed
debug.h can pull its definition of ksKernelEntry from benchmark_track.h
x86/arch/machine/hardware.h gets include via types.h (through the
compound_types.h header). As this header is defining compound types
it really only needs access to the basic types (i.e. stdint.h)
The lowest syscall number is -8, which doesnt' fit in 3 bits -> change
to 4.
Also, we were storing the -ve number, which also doesn't fit into 3
bits -> invert it when we store it.
* commit 'e3f764a65be484d89e29ebc22ea406f1438ae3d3':
Benchmark: move arch-dependent benchmark.c from api/ to new benchmark/ directory
Benchmark: Pack arch-independent benchmark-related files into separate directories
* commit 'cdc869309b69d04c8682f166755c26cc7a401667':
arm_hyp: Used cached value for num LRs
arm_hyp: Add lazy vcpu switching
arm_hyp: Declare armHSCurVCPU in header
arm_hyp: Correctly destroy armHSCurVCPU
arm_hyp: Move hype state into correct statedata header
Hardware debugging was already supported if using SYSCALL for kernel
invocations, this adds support for when using SYSENTER. SYSENTER
is special because when entering the kernel the TF flag is not masked,
so the case of taking a debug exception in the kernel needs to be
handled. Also, unlike ia32, there is a race between performing
popf and calling sysexit where interrupts can be received. This race
is avoided by performing a full state restore with iret if a thread
is single stepping.
The hypervisor state is declared in arch/32/statedata.c, but is
defined in arch/statedata.h. This commit moves the definitions to
arch/32/statedata.h to match all the other state in arch/32/statedata.c
Having a different name for the FLAGS register creates an unnecessary difference
between ia32 and x86_64 code since regardless of the name/size the bits in the
register mean exactly the same thing
This commit implements the body of SELFOUR-499. The API exposes the x86 DR0-7
and ARM coprocessor 14 features to userspace by virtualizing them as context-
switched registers in the TCB. Implemented as TCB invocations. This feature is
only built when CONFIG_HARDWARE_DEBUG_API is selected.
* Add low-level support routines for setting, unsetting, getting, enabling
and disabling breakpoints.
* Add support for single-stepping as well.
^ Single-stepping is not supported on ARMv6 since the hardware
doesn't have support.
^ ARM implements single-stepping as instruction breakpoints
configured to fault on every instruction -- this is achieved through
the "mismatch" mode, which is only supported from ARMv7 onwards.
* Also support explicit software break requests, a la "BKPT" and "INT $3".
* New invocations:
* seL4_TCB_SetBreakpoint().
* seL4_TCB_GetBreakpoint().
* seL4_TCB_UnsetBreakpoint().
* seL4_TCB_ConfigureSingleStepping().
* New constants:
^ Event types:
^ seL4_InstructionBreakpoint.
^ seL4_DataBreakpoint.
^ seL4_SoftwareBreakRequest.
^ Access types:
^ seL4_BreakOnRead.
^ seL4_BreakOnWrite.
^ seL4_BreakOnReadWrite.
^ Exports:
^ seL4_NumHWBreakpoints.
^ seL4_NumExclusiveBreakpoints.
^ seL4_NumExclusiveWatchpoints.
^ seL4_NumDualFunctionMonitors.
^ seL4_FirstBreakpoint.
^ seL4_FirstWatchpoint.
^ seL4_FirstDualFunctionMonitor.
