2020-05-14target/arm: Use correct GDB XML for M-profile coresPeter Maydell4-6/+48
GDB's remote protocol requires M-profile cores to use the feature name 'org.gnu.gdb.arm.m-profile' instead of the 'org.gnu.gdb.arm.core' feature used for A- and R-profile cores. We weren't doing this, which meant GDB treated our M-profile cores like A-profile ones. This mostly doesn't matter, but for instance means that it doesn't correctly handle backtraces where an M-profile exception frame is involved. Ship a copy of GDB's arm-m-profile.xml and use it on the M-profile cores. The integer registers have the same offsets as the arm-core.xml, but register 25 is the M-profile XPSR rather than the A-profile CPSR, so we need to update arm_cpu_gdb_read_register() and arm_cpu_gdb_write_register() to handle XSPR reads and writes.

2020-05-149pfs: local: ignore O_NOATIME if we don't have permissionsOmar Sandoval1-0/+13
QEMU's local 9pfs server passes through O_NOATIME from the client. If the QEMU process doesn't have permissions to use O_NOATIME (namely, it does not own the file nor have the CAP_FOWNER capability), the open will fail. This causes issues when from the client's point of view, it believes it has permissions to use O_NOATIME (e.g., a process running as root in the virtual machine). Additionally, overlayfs on Linux opens files on the lower layer using O_NOATIME, so in this case a 9pfs mount can't be used as a lower layer for overlayfs (cf. https://github.com/osandov/drgn/blob/dabfe1971951701da13863dbe6d8a1d172ad9650/vmtest/onoatimehack.c and https://github.com/NixOS/nixpkgs/issues/54509). Luckily, O_NOATIME is effectively a hint, and is often ignored by, e.g., network filesystems. open(2) notes that O_NOATIME "may not be effective on all filesystems. One example is NFS, where the server maintains the access time." This means that we can honor it when possible but fall back to ignoring it.

2020-05-13qcow2: introduce compression type featureDenis Plotnikov23-150/+365
The patch adds some preparation parts for incompatible compression type feature to qcow2 allowing the use different compression methods for image clusters (de)compressing. It is implied that the compression type is set on the image creation and can be changed only later by image conversion, thus compression type defines the only compression algorithm used for the image, and thus, for all image clusters. The goal of the feature is to add support of other compression methods to qcow2. For example, ZSTD which is more effective on compression than ZLIB. The default compression is ZLIB. Images created with ZLIB compression type are backward compatible with older qemu versions. Adding of the compression type breaks a number of tests because now the compression type is reported on image creation and there are some changes in the qcow2 header in size and offsets. The tests are fixed in the following ways: * filter out compression_type for many tests * fix header size, feature table size and backing file offset affected tests: 031, 036, 061, 080 header_size +=8: 1 byte compression type 7 bytes padding feature_table += 48: incompatible feature compression type backing_file_offset += 56 (8 + 48 -> header_change + feature_table_change) * add "compression type" for test output matching when it isn't filtered affected tests: 049, 060, 061, 065, 082, 085, 144, 182, 185, 198, 206, 242, 255, 274, 280 Signed-off-by: Denis Plotnikov <dplotnikov@virtuozzo.com> Reviewed-by: Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com> Reviewed-by: Eric Blake <eblake@redhat.com> Reviewed-by: Max Reitz <mreitz@redhat.com> QAPI part: Acked-by: Markus Armbruster <armbru@redhat.com> Message-Id: <20200507082521.29210-2-dplotnikov@virtuozzo.com> Signed-off-by: Max Reitz <mreitz@redhat.com>

2020-05-11target/arm: Fix tcg_gen_gvec_dup_imm vs DUP (indexed)Richard Henderson1-1/+5
DUP (indexed) can duplicate 128-bit elements, so using esz unconditionally can assert in tcg_gen_gvec_dup_imm.

2020-05-11hw/arm/musicpal: Map the UART devices unconditionallyPhilippe Mathieu-Daudé1-8/+4
I can't find proper documentation or datasheet, but it is likely a MMIO mapped serial device mapped in the 0x80000000..0x8000ffff range belongs to the SoC address space, thus is always mapped in the memory bus. Map the devices on the bus regardless a chardev is attached to it.
