2022-10-24dump: Reintroduce memory_offset and section_offsetJanosch Frank1-0/+2
section_offset will later be used to store the offset to the section data which will be stored last. For now memory_offset is only needed to make section_offset look nicer.

2022-10-24dump: Write ELF section headers right after ELF headerJanosch Frank1-17/+14
Let's start bundling the writes of the headers and of the data so we have a clear ordering between them. Since the ELF header uses offsets to the headers we can freely order them.

2022-10-24dump: Use a buffer for ELF section data and headersJanosch Frank2-24/+53
Currently we're writing the NULL section header if we overflow the physical header number in the ELF header. But in the future we'll add custom section headers AND section data. To facilitate this we need to rearange section handling a bit. As with the other ELF headers we split the code into a prepare and a write step.

2022-10-24tests/9p: merge *walk*() functionsChristian Schoenebeck3-140/+198
Introduce declarative function calls. There are currently 4 different functions for sending a 9p 'Twalk' request: v9fs_twalk(), do_walk(), do_walk_rqids() and do_walk_expect_error(). They are all doing the same thing, just in a slightly different way and with slightly different function arguments. Merge those 4 functions into a single function by using a struct for function call arguments and use designated initializers when calling this function to turn usage into a declarative approach, which is better readable and easier to maintain. Also move private functions genfid(), split() and split_free() from virtio-9p-test.c to virtio-9p-client.c.

2022-10-249pfs: use GHashTable for fid tableLinus Heckemann2-84/+112
The previous implementation would iterate over the fid table for lookup operations, resulting in an operation with O(n) complexity on the number of open files and poor cache locality -- for every open, stat, read, write, etc operation. This change uses a hashtable for this instead, significantly improving the performance of the 9p filesystem. The runtime of NixOS's simple installer test, which copies ~122k files totalling ~1.8GiB from 9p, decreased by a factor of about 10.

2022-10-24tests/9p: split virtio-9p-test.c into tests and 9p client partChristian Schoenebeck4-744/+849
This patch is pure refactoring, it does not change behaviour. virtio-9p-test.c grew to 1657 lines. Let's split this file up between actual 9p test cases vs. 9p test client, to make it easier to concentrate on the actual 9p tests. Move the 9p test client code to a new unit virtio-9p-client.c, which are basically all functions and types prefixed with v9fs_* already. Note that some client wrapper functions (do_*) are preserved in virtio-9p-test.c, simply because these wrapper functions are going to be wiped with subsequent patches anyway. As the global QGuestAllocator variable is moved to virtio-9p-client.c, add a new function v9fs_set_allocator() to be used by virtio-9p-test.c instead of fiddling with a global variable across units and libraries.

2022-10-24m68k: write bootinfo as rom section and re-randomize on rebootJason A. Donenfeld3-59/+111
Rather than poking directly into RAM, add the bootinfo block as a proper ROM, so that it's restored when rebooting the system. This way, if the guest corrupts any of the bootinfo items, but then tries to reboot, it'll still be restored back to normal as expected. Then, since the RNG seed needs to be fresh on each boot, regenerate the RNG seed in the ROM when reseting the CPU.

2022-10-22target/i386: implement FMA instructionsPaolo Bonzini8-3/+135
The only issue with FMA instructions is that there are _a lot_ of them (30 opcodes, each of which comes in up to 4 versions depending on VEX.W and VEX.L; a total of 96 possibilities). However, they can be implement with only 6 helpers, two for scalar operations and four for packed operations. (Scalar versions do not do any merging; they only affect the bottom 32 or 64 bits of the output operand. Therefore, there is no separate XMM and YMM of the scalar helpers). First, we can reduce the number of helpers to one third by passing four operands (one output and three inputs); the reordering of which operands go to the multiply and which go to the add is done in emit.c. Second, the different instructions also dispatch to the same softfloat function, so the flags for float32_muladd and float64_muladd are passed in the helper as int arguments, with a little extra complication to handle FMADDSUB and FMSUBADD.

2022-10-21m68k: rework BI_VIRT_RNG_SEED as BI_RNG_SEEDJason A. Donenfeld4-6/+21
Following a change on the kernel side (see link), pass BI_RNG_SEED instead of BI_VIRT_RNG_SEED. This should have no impact on compatibility, as there will simply be no effect if it's an old kernel, which is how things have always been. We then use this as an opportunity to add this to q800, since now we can, which is a nice improvement.

2022-10-20target/i386: implement F16C instructionsPaolo Bonzini9-6/+89
F16C only consists of two instructions, which are a bit peculiar nevertheless. First, they access only the low half of an YMM or XMM register for the packed-half operand; the exact size still depends on the VEX.L flag. This is similar to the existing avx_movx flag, but not exactly because avx_movx is hardcoded to affect operand 2. To this end I added a "ph" format name; it's possible to reuse this approach for the VPMOVSX and VPMOVZX instructions, though that would also require adding two more formats for the low-quarter and low-eighth of an operand. Second, VCVTPS2PH is somewhat weird because it *stores* the result of the instruction into memory rather than loading it.

2022-10-20hw/ide/microdrive: Use device_cold_reset() for self-resetsPeter Maydell1-4/+4
Currently the microdrive code uses device_legacy_reset() to reset itself, and has its reset method call reset on the IDE bus as the last thing it does. Switch to using device_cold_reset(). The only concrete microdrive device is the TYPE_DSCM1XXXX; it is not command-line pluggable, so it is used only by the old pxa2xx Arm boards 'akita', 'borzoi', 'spitz', 'terrier' and 'tosa'. You might think that this would result in the IDE bus being reset automatically, but it does not, because the IDEBus type does not set the BusClass::reset method. Instead the controller must explicitly call ide_bus_reset(). We therefore leave that call in md_reset(). Note also that because the PCMCIA card device is a direct subclass of TYPE_DEVICE and we don't model the PCMCIA controller-to-card interface as a qbus, PCMCIA cards are not on any qbus and so they don't get reset when the system is reset. The reset only happens via the dscm1xxxx_attach() and dscm1xxxx_detach() functions during machine creation. Because our aim here is merely to try to get rid of calls to the device_legacy_reset() function, we leave these other dubious reset-related issues alone. (They all stem from this code being absolutely ancient.)
