Change 32558ce7a4 introduced specific directories for the socket dir when using python/qemu/machine.py:QEMUMachine. iotests probably didn't catch the condition that two simultaneous QEMUMachine instances, without manually set temporary or socket dirs would clash.

2019-10-28esp: add pseudo-DMA as used by MacintoshLaurent Vivier
There is no DMA in Quadra 800, so the CPU reads/writes the data from the PDMA register (offset 0x100, ESP_PDMA in hw/m68k/q800.c) and copies them to/from the memory. There is a nice assembly loop in the kernel to do that, see linux/drivers/scsi/mac_esp.c:MAC_ESP_PDMA_LOOP(). The start of the transfer is triggered by the DREQ interrupt (see linux mac_esp_send_pdma_cmd()), the CPU polls on the IRQ flag to start the transfer after a SCSI command has been sent (in Quadra 800 it goes through the VIA2, the via2-irq line and the vIFR register) The Macintosh hardware includes hardware handshaking to prevent the CPU from reading invalid data or writing data faster than the peripheral device can accept it. This is the "blind mode", and from the doc: "Approximate maximum SCSI transfer rates within a blocks are 1.4 MB per second for blind transfers in the Macintosh II" Some references can be found in: Apple Macintosh Family Hardware Reference, ISBN 0-201-19255-1 Guide to the Macintosh Family Hardware, ISBN-0-201-52405-8 Acked-by: Dr. David Alan Gilbert <dgilbert@redhat.com> Co-developed-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk> Signed-off-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk> Signed-off-by: Laurent Vivier <laurent@vivier.eu> Acked-by: Paolo Bonzini <pbonzini@redhat.com> Message-Id: <20191026164546.30020-4-laurent@vivier.eu>

2019-10-28target/riscv: PMP violation due to wrong size parameterDayeol Lee
riscv_cpu_tlb_fill() uses the `size` parameter to check PMP violation using pmp_hart_has_privs(). However, if the size is unknown (=0), the ending address will be `addr - 1` as it is `addr + size - 1` in `pmp_hart_has_privs()`. This always causes a false PMP violation on the starting address of the range, as `addr - 1` is not in the range. In order to fix, we just assume that all bytes from addr to the end of the page will be accessed if the size is unknown.

Libgcrypt 1.8.0 added support for the XTS mode. Use this because long term we wish to delete QEMU's XTS impl to avoid carrying private crypto algorithm impls. As an added benefit, using this improves performance from 531 MB/sec to 670 MB/sec, since we are avoiding several layers of function call indirection. This is even more noticable with the gcrypt builds in Fedora or RHEL-8 which have a non-upstream patch for FIPS mode which does mutex locking. This is catastrophic for encryption performance with small block sizes, meaning this patch improves encryption from 240 MB/sec to 670 MB/sec.

2019-10-28tests/tcg: drop test-i386-fprem from TESTS when not SLOWAlex Bennée
This is a very slow running test which we only enable explicitly. However having it in the TESTS lists would confuse additional tests like the plugins test which want to run on all currently enabled tests.

2019-10-28tests/tcg/Makefile.target: fix path to config-host.makAlex Bennée
Since moving where the tests are run the path to config-host.mak has been wrong. This doesn't affect much but things like the time fallback for CONFIG_DEBUG_TCG and will also get in the way of checking for PLUGINS support.

2019-10-28plugin: add qemu_plugin_outs helperAlex Bennée
Having the plugins grab stdout and spew stuff there is a bit ugly and certainly makes the tests look ugly. Provide a hook back into QEMU which can be redirected as needed. Signed-off-by: Alex Bennée <alex.bennee@linaro.org> Reviewed-by: Aaron Lindsay <aaron@os.amperecomputing.com>
2019-10-28plugin: add qemu_plugin_insn_disas helperAlex Bennée
Give the plugins access to the QEMU dissasembler so they don't have to re-invent the wheel. We generate a warning when there are spare bytes in the decode buffer. This is usually due to the front end loading in more bytes than decoded. Signed-off-by: Alex Bennée <alex.bennee@linaro.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org>
