| * | linux-user: Add guest memory layout to exception dumpHelge Deller2022-10-253-16/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the emulation stops with a hard exception it's very useful for debugging purposes to dump the current guest memory layout (for an example see /proc/self/maps) beside the CPU registers. The open_self_maps() function provides such a memory dump, but since it's located in the syscall.c file, various changes (add #includes, make this function externally visible, ...) are needed to be able to call it from the existing EXCP_DUMP() macro. This patch takes another approach by re-defining EXCP_DUMP() to call target_exception_dump(), which is in syscall.c, consolidates the log print functions and allows to add the call to dump the memory layout. Beside a reduced code footprint, this approach keeps the changes across the various callers minimal, and keeps EXCP_DUMP() highlighted as important macro/function.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | 9pfs: use GHashTable for fid tableLinus Heckemann2022-10-242-84/+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.

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.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | target/i386: decode-new: avoid out-of-bounds access to xmm_regs[-1]Paolo Bonzini2022-10-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the destination is a memory register, op->n is -1. Going through tcg_gen_gvec_dup_imm path is both useless (the value has been stored by the gen_* function already) and wrong because of the out-of-bounds access.
