3039fd4b6e tests/qtest: i440fx-test: Rewrite create_blob_file() to be portable
Previously request_{bios, pflash} cases were skipped on win32, mainly
due to create_blob_file() calling mmap() which does not exist on win32.
This rewirtes create_blob_file() to be portable, so that we can enable
these cases on Windows.

Commit 584acf34cb ("ati-vga: Fix reverse bit blts") introduced
the local dst_x and dst_y which adjust the (x, y) coordinates
depending on the direction in the SRCCOPY ROP3 operation, but
forgot to address the same issue for the PATCOPY, BLACKNESS and
WHITENESS operations, which also call pixman_fill().

Fix that now by using the adjusted coordinates in the pixman_fill
call, and update the related debug printf().

0cbc8bd469 audio: remove abort() in audio_bug()
Commit ab32b78cd1 "audio: Simplify audio_bug() removing old code"
introduced abort() in audio_bug() for regular builds.

audio_bug() was never meant to abort QEMU for the following
reasons.

  - There's code in audio_bug() that expects audio_bug() gets
    called more than once with error condition true. The variable
    'shown' is only 0 on first error.

  - All call sites test the return code of audio_bug(), print
    an error context message and handle the errror.

  - The abort() in audio_bug() enables a class of guest-triggered
    aborts similar to the Launchpad Bug #1910603 at
    https://bugs.launchpad.net/bugs/1910603.

a42bd00166 target/riscv: debug: Determine the trigger type from tdata1.type
Current RISC-V debug assumes that only type 2 trigger is supported.
To allow more types of triggers to be supported in the future
(e.g. type 6 trigger, which is similar to type 2 trigger with additional
 functionality), we should determine the trigger type from tdata1.type.

RV_MAX_TRIGGERS is also introduced in replacement of TRIGGER_TYPE2_NUM.

2cfa963126 m68k: align bootinfo strings and data to 4 bytes
Various tools, such as kexec-tools and m68k-bootinfo, expect each
bootinfo entry to be aligned to 4 bytes, not 2 bytes. So adjust the
padding to fill this out as such.

Also, break apart the padding additions from the other field length
additions, so that it's more clear why these magic numbers are being
added, and comment them too.

b342e56b23 target/m68k: use M68K_FEATURE_MOVEFROMSR_PRIV feature for move_from_sr privilege check
Now that M68K_FEATURE_M68000 has been renamed to M68K_FEATURE_M68K it is easier
to see that the privilege exception check is wrong: it is currently only generated
for ColdFire CPUs when in fact it should also be generated for Motorola CPUs from
the 68010 onwards.

Introduce a new M68K_FEATURE_MOVEFROMSR_PRIV feature which is set for all non-
Motorola CPUs, and for all Motorola CPUs from the 68010 onwards and use it to
determine whether a privilege exception should be generated for the MOVE-from-SR
instruction.

2dc7bf63cf target/m68k: increase size of m68k CPU features from uint32_t to uint64_t
There are already 32 feature bits in use, so change the size of the m68k
CPU features to uint64_t (along with the associated m68k_feature()
functions) to allow up to 64 feature bits to be used.

At the same time make use of the BIT_ULL() macro when reading/writing
the CPU feature bits to improve readability, and also update m68k_feature()
to return a bool rather than an int.

9dfa6c2aec hw/riscv/sifive_e: Fix inheritance of SiFiveEState
SiFiveEState inherits from SysBusDevice while it's TypeInfo claims it to
inherit from TYPE_MACHINE. This is an inconsistency which can cause
undefined behavior such as memory corruption.

Change SiFiveEState to inherit from MachineState since it is registered
as a machine.

9e37653b5c target/riscv: Check the correct exception cause in vector GDB stub
After RISCVException enum is introduced, riscv_csrrw_debug() returns
RISCV_EXCP_NONE to indicate there's no error. RISC-V vector GDB stub
should check the result against RISCV_EXCP_NONE instead of value 0.
Otherwise, 'E14' packet would be incorrectly reported for vector CSRs
when using "info reg vector" GDB command.

a06fded82e hw/riscv: opentitan: Expose the resetvec as a SoC property
On the OpenTitan hardware the resetvec is fixed at the start of ROM. In
QEMU we don't run the ROM code and instead just jump to the next stage.
This means we need to be a little more flexible about what the resetvec
is.

This patch allows us to set the resetvec from the command line with
something like this:
    -global driver=riscv.lowrisc.ibex.soc,property=resetvec,value=0x20000400

This way as the next stage changes we can update the resetvec.

be used to set the resetvec (depending on your timing), let's instead
just set the resetvec directly in the env struct.

This allows us to set the reset vec from the command line with:
    -global driver=riscv.hart_array,property=resetvec,value=0x20000400
