Subject: [PATCH v2 00/17] x86/hvm: I/O emulation cleanup and fix
Date: Thu, 11 Jun 2015 16:42:44 +0100 [thread overview]
Message-ID: <1434037381-10917-1-git-send-email-paul.durrant@citrix.com> (raw)
This patch series re-works much of the code involved in emulation of port
and memory mapped I/O for HVM guests.
The code has become very convoluted and, at least by inspection, certain
emulations will apparently malfunction.
The series is broken down into 17 patches (which are also available in
my xenbits repo: http://xenbits.xen.org/gitweb/?p=people/pauldu/xen.git
on the emulation22 branch) as follows:
0001-x86-hvm-simplify-hvmemul_do_io.patch
0002-x86-hvm-re-name-struct-hvm_mmio_handler-to-hvm_mmio_.patch
0003-x86-hvm-unify-internal-portio-and-mmio-intercepts.patch
0004-x86-hvm-unify-dpci-portio-intercept-with-standard-po.patch
0005-x86-hvm-unify-stdvga-mmio-intercept-with-standard-mm.patch
0006-x86-hvm-revert-82ed8716b-fix-direct-PCI-port-I-O-emu.patch
0007-x86-hvm-only-call-hvm_io_assist-from-hvm_wait_for_io.patch
0008-x86-hvm-split-I-O-completion-handling-from-state-mod.patch
0009-x86-hvm-remove-hvm_io_pending-check-in-hvmemul_do_io.patch
0010-x86-hvm-remove-HVMIO_dispatched-I-O-state.patch
0011-x86-hvm-remove-hvm_io_state-enumeration.patch
0012-x86-hvm-use-ioreq_t-to-track-in-flight-state.patch
0013-x86-hvm-only-acquire-RAM-pages-for-emulation-when-we.patch
0014-x86-hvm-remove-extraneous-parameter-from-hvmtrace_io.patch
0015-x86-hvm-make-sure-translated-MMIO-reads-or-writes-fa.patch
0016-x86-hvm-remove-multiple-open-coded-chunking-loops.patch
0017-x86-hvm-track-large-memory-mapped-accesses-by-buffer.patch
v2:
- Removed bogus assertion from patch 16
- Re-worked patch 17 after basic testing of back-port onto XenServer
