Return value of read/write simcalls is not calculated correctly in case of operations crossing page boundary and in case of short reads/writes. Read and write simcalls should return the size of data actually read/written or -1 in case of error. Cc: qemu-stable@nongnu.org Signed-off-by: NMax Filippov <jcmvbkbc@gmail.com>

Read and write simcalls map physical memory to access I/O buffers, but 'read' simcall need to map it for writing and 'write' simcall need to map it for reading, i.e. the opposite of what they do now. Fix that. Cc: qemu-stable@nongnu.org Signed-off-by: NMax Filippov <jcmvbkbc@gmail.com>

In theory this would re-enable usage of QEMU on an armv4 host. Whether this is worthwhile is debatable -- we've been unconditionally issuing the armv5t BX instruction in the prologue since 2011 without complaint. Possibly we should simply require an armv6 host.

Optimizations to cross-page chaining and indirect branches make performance more sensitive to the hit rate of tb_jmp_cache. The constraint of reserving some bits for the page number lowers the achievable quality of the hashing function. However, user-mode does not have this requirement. Thus, with this change we use for user-mode a hashing function that is both faster and of better quality than the previous one. Measurements: Note: baseline (i.e. speedup == 1x) is QEMU v2.9.0. - SPECint06 (test set), x86_64-linux-user.

Instead of exporting goto_ptr directly to TCG frontends, export tcg_gen_lookup_and_goto_ptr(), which calls goto_ptr with the pointer returned by the lookup_tb_ptr() helper. This is the only use case we have for goto_ptr and lookup_tb_ptr, so having this function is very convenient. Furthermore, it trivially allows us to avoid calling the lookup helper if goto_ptr is not implemented by the backend. Reviewed-by: NAlex Bennée <alex.bennee@linaro.org> Signed-off-by: NEmilio G.

The help text for the thread sub option of the accel option is missing a newline at the end. This is annoying as it makes it hard to see the help text for the next option. Add the new line so that the following option help text (-smp) is displayed on a new line rather on the same line and directly after the thread help.

In the process of getting rid of docs/qmp-commands.txt, we managed to regress on some of the text that changed after the point where the move was first branched and when the move actually occurred. For example, commit 3282eca4 for blockdev-snapshot re-added the extra "options" layer which had been cleaned up in commit 0153d2f5. This clears up all regressions identified over the range 02b351d8..bd6092e4: https://lists.gnu.org/archive/html/qemu-devel/2017-05/msg05127.html as well as a cleanup to x-blockdev-remove-medium to prefer 'id' over 'device' (matching the cleanup for 'eject').
