gdbstub: Fix single-step issue by confirming 'vContSupported+' feature to gdb
Recently when debugging an arm32 system on qemu, I found sometimes the
single-step command (stepi) is not working. This can be reproduced by
below steps:
1) start qemu-system-arm -s -S .. and wait for gdb connection.
2) start gdb and connect to qemu. In my case, gdb gets a wrong value
(0x60) for PC, which is an another bug.
3) After connected, type 'stepi' and expect it will stop at next ins.
But, it has never stopped. This because:
1) We doesn't report ‘vContSupported’ feature to gdb explicitly and gdb
think we do not support it. In this case, gdb use a software breakpoint
to emulate single-step.
2) Since gdb gets a wrong initial value of PC, then gdb inserts a
breakpoint to wrong place (PC+4).
Not only for the arm target, Philippe has also encountered this on MIPS.
Probably gdb has different assumption for different architectures.
Since we do support ‘vContSupported’ query command, so let's tell gdb that
we support it.
Before this change, gdb send below 'Z0' packet to implement single-step:
gdb_handle_packet: Z0,4,4
After this change, gdb send "vCont;s.." which is expected:
gdb_handle_packet: vCont?
put_packet: vCont;c;C;s;S
gdb_handle_packet: vCont;s:p1.1;c:p1.-1

tcg: Remove CONFIG_VECTOR16
The comment in tcg-runtime-gvec.c about CONFIG_VECTOR16 says that
tcg-op-gvec.c has eliminated size 8 vectors, and only passes on
multiples of 16. This may have been true of the first few operations,
but is not true of all operations.
In particular, multiply, shift by scalar, and compare of 8- and 16-bit
elements are not expanded inline if host vector operations are not
supported.
For an x86_64 host that does not support AVX, this means that we will
fall back to the helper, which will attempt to use SSE instructions,
which will SEGV on an invalid 8-byte aligned memory operation.
This patch simply removes the CONFIG_VECTOR16 code and configuration
without further simplification.

A given RISU testcase for SVE can produce

usb-serial: chunk data to wMaxPacketSize
usb-serial has issues with xHCI controllers where data is lost in the
VM. Inspecting the URBs in the guest, EHCI starts every 64 byte boundary
(wMaxPacketSize) with a header. EHCI hands packets into
usb_serial_token_in() with size 64, so these cannot cross the 64 byte
boundary. The xHCI controller has packets of 512 bytes and the usb-serial
will just write through the 64 byte boundary. In the guest, this means
data bytes are interpreted as header, so data bytes don't make it out
the serial interface.
Re-work usb_serial_token_in to chunk data into 64 byte units - 2 byte
header and 62 bytes data. The Linux driver reads wMaxPacketSize to find
the chunk size, so we match that.
Real hardware was observed to pass in 512 byte URBs (496 bytes data +
8 * 2 byte headers). Since usb-serial only buffers 384 bytes of data,
usb-serial will pass in 6 64 byte blocks and 1 12 byte partial block for
462 bytes max.
