Alejandro Gomez-Londono 796887d9b1 Removes all trailing whitespaces 2017-07-12 15:13:51 +10:00
Joel Beeren 81064fdb55 idle-thread-pd: run idle thread with the global PD all the time. 
This avoids the multicore scenario of the idle thread running in the
address space that has been deleted by a thread running on another core.

Miki Tanaka 9f3924d1ea design spec: adjust skeleton files for unified haskell files 2017-07-03 10:31:34 +10:00
Miki Tanaka d8d1ee014c haskell: unify arm and arm-hyp haskell files 
- both ARM and ARM_HYP haskell specs are now generated from the same set of files using cpp
- callbacks and platform files are merged into one directory (ARM)
- remove check-arm-hyp.py now that there are no ARM_HYP.lhs files

Miki Tanaka 41fe1a0845 update proofs for SELFOUR-30/291 "Reschedule on self-modification" 
- SELFOUR-30 Reschedule when changing own IPC buffer
Previously if you invoked the TCB of the current thread and
changed the IPC buffer frame this would not immediately take
affect, as the kernels view of the current IPC buffer is
updated in Arch_switchToThread. This change forces Arch_switchToThread
to get called, even if we would switch back to the original
thread.

- SELFOUR-291 Reschedule when changing own registers
Previously if you wrote to TCB of the current thread and
changed the TLS_BASE this would not immediately take
affect, as the kernel only updates this register in
Arch_switchToThread. This change forces Arch_switchToThread
to get called, even if we would switch back to the original
thread.

Alejandro Gomez-Londono 758ed38246 arm aspec: definitions + map instead of ad-hoc upto_enum in create_mapping_entries 
* Defined largePagePTE_offsets and superSectionPDE_offsets as is the
    case in arm-hyp

  * Used a map over largePagePTE_offsets/superSectionPDE_offsets
    instead of upto_enum

Gerwin Klein 7bb68406d6 arm-hyp design/skel: define pageBase manually 
pageBase is now generic in Haskell, but since PAddr, VPtr etc all map to word
in Isabelle, the generic type declaration would lead to an error.

Only necessary in ARM_HYP, but could be done in ARM as well if necessary.

Gerwin Klein 424df79856 arm-hyp haskell: resolveVAddr needs to mask 
LargePages and SuperSections are not duplicated as in normal ARM, so we need
to mask to get to the base address.
 2017-06-19 14:32:38 +10:00
Gerwin Klein cbc528beba arm-hyp haskell: make LargePage and SuperSection contiguous 
In HYP mode, large pages and super sections are encoded by a set of small
pages and section entries that have the contiguous bit set. The hardware must
be able to ignore that bit and still make the correct translation, so they
most point to the correct base address in each entry, instead of being
duplicates as in normal (non-HYP) mode.
