Hi,
This is the latest iteration of the plugins series. The main changes
from the last version are:
- dropped passing of haddr to plugins
This makes the code for handling the plugins less invasive in the
softmmu path at the cost of offloading processing to the plugin if it
wants the value. We rely on the fact that the TLB is per vCPU so a
helper can just trigger a re-query of the TLB to get the final
address.
Part of that change involved embedding the MMU index in the meminfo
field for tracing. I see there are some other patches on the list for
messing with TCGMemOp so there might be a clash coming up.
- translator_ld goes direct to softmmu/user functions
I also mark the [SOFTMMU_]CODE_ACCESS helpers as deprecated. There is
more work to be done to clean up all the current uses of code access
helpers but ideally the only thing that should be peaking at code is
the translator loop itself. However a bunch of helpers have taken to
using code loading functions to peak at the instruction just executed
to figure out what to do. Once those have been fixed then we can
remove those helpers.
Other more minor fixes can be found documented bellow the --- in the
individual patches.
This series also includes the semihosting patches as they are a
pre-requisite for the translator_ld patches for ARM.
Once the tree opens up for development again I hope to get the
semihosting and trivial clean-up patches merged quickly so the patch
count for the plugins patches proper can be reduced a bit.
The following patches need review
patch 0004/target arm remove run time semihosting checks.patch
patch 0005/includes remove stale smp max _cpus externs.patch
patch 0007/trace add mmu_index to mem_info.patch
patch 0011/docs devel add plugins.rst design document.patch
patch 0012/configure add enable plugins MOVE TO END.patch
patch 0015/plugin add implementation of the api.patch
patch 0024/plugins implement helpers for resolving hwaddr.patch
patch 0047/tests tcg enable plugin testing.patch
patch 0048/tests plugin add a hotblocks plugin.patch
patch 0050/tests plugin add instruction execution breakdown.patch
patch 0051/tests plugin add hotpages plugin to breakdown mem.patch
patch 0053/include exec wrap cpu_ldst.h in CONFIG_TCG.patch
