Even the first kernel register window after the switch from userspace stack needs
proper register window save area [sparc64]. |

sparc64 work.
- the syscall wrapper needs to use the "memory"
clobber specifier to prevent over-optimization.
- on sparc64, the user address space spans the whole
64-bit space and therefore the macro
USER_ADDRESS_SPACE_SIZE_ARCH, as it was defined,
overflows to 0
- stop using USER_ADDRESS_SPACE_SIZE_ARCH and define
MAX_HEAP_SIZE instead
- in our situation when kernel and user address spaces
are separate, the G (global) bit cannot be used
(there is no point in it anymore)
- add the DEBUG() macro to stdio.h; DEBUG() uses
SYS_IO and is a good debugging tool for getting
early userspace to work |

sparc64 update.
- Prototype userspace layer implementation that
at least relates to sparc64 and compiles cleanly.
- Fixes for kernel's preemptible_handler and code
related to running userspace.
- Enable userspace. Several dozen instructions
are now run in userspace! We are pretty near
the userspace milestone for sparc64. |

A lot of untested sparc64 stuff:
- Write ASID to hardware when a thread is about to run in userspace.
- Add userspace() and switch_to_userspace() functions.
- Handle special cases when the userspace spill/fill handler causes MMU trap.
- Resolve some TODOs in the existing sparc64 code.
- sparc64 has now C99 compliant header guards.
- Formatting and indentation fixes. |

- Convert interrupt_vector trap handler and some mm related trap handlers to
use preemptibe_handler(), which is essential for traps coming from userspace.
- Add fast_data_access_protection() handler. |

sparc64 work.
More bits needed to reach the userspace milestone were added.
The preemptible_handler(), still a prototype, now contains all functionality it needs.
Some sanitation was added to functions expecting page-aligned pointers to
userspace window buffer. |

sparc64 work.
- Modify before_thread_runs_arch() to store addresses of the kernel stack and
userspace window buffer, resp., to registers %g6 and %g7, resp, in the
alternate and interrupt global sets.
- Modify after_thread_ran_arch() to sample %g7 from the alternate globals.
- Implement trap handler for spilling register windows into userspace window buffer.
- Implement assembly language functions to access %g6 and %g7 registers in the alternate sets.
- Initialize the trap table so that there are now also spill_1_normal, spill_2_normal,
spill_0_other and fill_1_normal handlers. These handlers are used in different situations
and for different purposes. |
