[RFC PATCH] softmmu: Fix async_run_on_cpu() use in tcg_commit_cpu()

CPUState::halt_cond is an accelerator specific pointer, used in particular by TCG (which tcg_commit() is about). The pointer is set by the AccelOpsClass::create_vcpu_thread() handler. AccelOpsClass::create_vcpu_thread() is called by the generic qemu_init_vcpu(), which expect the accelerator

[PATCH 09/14] target/arm: Implement the SET* instructions

Implement the SET* instructions which collectively implement a "memset" operation. These come in a set of three, eg SETP (prologue), SETM (main), SETE (epilogue), and each of those has different flavours to indicate whether memory accesses should be unpriv or non-temporal. This commit does not

[PATCH 11/14] target/arm: Implement the SETG* instructions

The FEAT_MOPS SETG* instructions are very similar to the SET* instructions, but as well as setting memory contents they also set the MTE tags. They are architecturally required to operate on tag-granule aligned regions only. Signed-off-by: Peter Maydell --- target/arm/internals.h | 10

[PATCH 06/14] target/arm: Define syndrome function for MOPS exceptions

The FEAT_MOPS memory operations can raise a Memory Copy or Memory Set exception if a copy or set instruction is executed when the CPU register state is not correct for that instruction. Define the usual syn_* function that constructs the syndrome register value for these exceptions.

[PATCH 01/14] target/arm: Remove unused allocation_tag_mem() argument

The allocation_tag_mem() function takes an argument tag_size, but it never uses it. Remove the argument. In mte_probe_int() in particular this also lets us delete the code computing the value we were passing in. Signed-off-by: Peter Maydell Reviewed-by: Richard Henderson ---

[PATCH 07/14] target/arm: New function allocation_tag_mem_probe()

For the FEAT_MOPS operations, the existing allocation_tag_mem() function almost does what we want, but it will take a watchpoint exception even for an ra == 0 probe request, and it requires that the caller guarantee that the memory is accessible. For FEAT_MOPS we want a function that will not

[PATCH 10/14] target/arm: Define new TB flag for ATA0

Currently the only tag-setting instructions always do so in the context of the current EL, and so we only need one ATA bit in the TB flags. The FEAT_MOPS SETG instructions include ones which set tags for a non-privileged access, so we now also need the equivalent "are tags enabled?" information

[PATCH 08/14] target/arm: Implement MTE tag-checking functions for FEAT_MOPS

The FEAT_MOPS instructions need a couple of helper routines that check for MTE tag failures: * mte_mops_probe() checks whether there is going to be a tag error in the next up-to-a-page worth of data * mte_check_fail() is an existing function to record the fact of a tag failure, which we

[PATCH 05/14] target/arm: Pass unpriv bool to get_a64_user_mem_index()

In every place that we call the get_a64_user_mem_index() function we do it like this: memidx = a->unpriv ? get_a64_user_mem_index(s) : get_mem_index(s); Refactor so the caller passes in the bool that says whether they want the 'unpriv' or 'normal' mem_index rather than having to do the ?:

The LDRT/STRT "unprivileged load/store" instructions behave like normal ones if executed at EL0. We handle this correctly for the load/store semantics, but get the MTE checking wrong. We always look at s->mte_active[is_unpriv] to see whether we should be doing MTE checks, but in hflags.c when we

[PATCH v3 0/5] Support message-based DMA in vfio-user server

This series adds basic support for message-based DMA in qemu's vfio-user server. This is useful for cases where the client does not provide file descriptors for accessing system memory via memory mappings. My motivating use case is to hook up device models as PCIe endpoints to a hardware design.
