2016-10-07qemu-doc: merge qemu-tech and qemu-docPaolo Bonzini1-44/+12
Merge what is left of qemu-tech into the main manual as an appendix. Ultimately we should have a new internals manual built from docs/, and then the "Translator Internals" parts of qemu-tech could move to docs/ as well. The bits on limitation and features of CPU emulation should remain in qemu-doc. Reviewed-by: Emilio G. Cota <cota@braap.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2016-10-07qemu-tech: rewrite some partsPaolo Bonzini1-82/+42
Drop most the device emulation part and merge the rest into the description of the MMU. Make some bits more up-to-date. Reviewed-by: Emilio G. Cota <cota@braap.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2016-10-07qemu-tech: reorganize contentPaolo Bonzini1-97/+74
Split more parts into separate chapters, place comparison last, rename "Introduction" to "CPU emulation". Reviewed-by: Emilio G. Cota <cota@braap.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2016-10-07qemu-tech: move user mode emulation features from qemu-techPaolo Bonzini1-71/+0
These are interesting for users too, since nowadays most qemu-user users are going to be somewhat technical rather than just people that want to run Wine. Some detail is lost, on the other hand some of the information I removed (e.g. basic block unchaining) was obsolete. Reviewed-by: Emilio G.

2016-10-07qemu-doc: replace introduction with the one from the internals manualPaolo Bonzini1-88/+0
The user manual has an obsolete introduction, and the one in the internals manual lists QEMU's features quite nicely. Drop the obsolete content and remove generic user-level documentation from qemu-tech. Reviewed-by: Emilio G. Cota <cota@braap.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2016-09-15Remove remainders of HPPA backendThomas Huth1-2/+1
The HPPA backend has been removed by the following commit: 802b5081233a6b643a8b135a5facaf14bafaa77d tcg-hppa: Remove tcg backend But some small pieces of the HPPA backend still survived until today. Since we also do not have support for a HPPA target in QEMU, we can nowadays safely remove the remaining HPPA parts (like the disassembler code, or the detection of HPPA in the configure script).

2016-02-23tcg: Rename tcg-target.c to tcg-target.inc.cPeter Maydell1-1/+1
Rename the per-architecture tcg-target.c files to tcg-target.inc.c. This makes it clearer that they are not intended to be standalone C files, but are instead #included into another source file.

2012-05-01Drop darwin-userAndreas Färber1-2/+1
It's been orphaned, not compiling for a long time and despite Apple's drop of their Rosetta ppc emulation technology with Mac OS X Lion no one has stepped up to fix it. Testing necessary changes wrt QOM'ification thus is impossible, so we might as well remove it completely.

2010-02-10Documentation: Use UTF-8 encoding and fix one wrong encodingStefan Weil1-0/+4
At least for Linux distributions UTF-8 is now standard, so the QEMU documentation should use this encoding, too. Even if there was currently only a single special character using ISO-8859-1, this might change in the future. So the texinfo keywords @documentlanguage and @documentencoding now document the language and the encoding. The special character was changed to UTF-8 (it could also have been changed to an x, but the original cross looks really nice if it is displayed correctly). These changes fix the html presentation at http://www.qemu.org/qemu-doc.html#SEC65 (ARM System emulator).

2010-02-10Documentation: Add direntry for info formatStefan Weil1-0/+6
update-info-dir maintains an index of all available documentation in info format (the file /usr/share/info/dir). It reads special @direntry tags in info files. This patch (extracted from a larger patch provided by Dirk Ullrich) adds these tags for qemu-doc.info and qemu-tech.info.

2009-08-24Unbreak large mem support by removing kqemuAnthony Liguori1-2/+2
kqemu introduces a number of restrictions on the i386 target. The worst is that it prevents large memory from working in the default build. Furthermore, kqemu is fundamentally flawed in a number of ways. It relies on the TSC as a time source which will not be reliable on a multiple processor system in userspace. Since most modern processors are multicore, this severely limits the utility of kqemu. kvm is a viable alternative for people looking to accelerate qemu and has the benefit of being supported by the upstream Linux kernel. If someone can implement work arounds to remove the restrictions introduced by kqemu, I'm happy to avoid and/or revert this patch. N.B. kqemu will still function in the 0.11 series but this patch removes it from the 0.12 series. Paul, please Ack or Nack this patch. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
