2024-03-22target/riscv: enable 'vstart_eq_zero' in the end of insnsIvan Klokov
The vstart_eq_zero flag is updated at the beginning of the translation phase from the env->vstart variable. During the execution phase all functions will set env->vstart = 0 after a successful execution, but the vstart_eq_zero flag remains the same as at the start of the block. This will wrongly cause SIGILLs in translations that requires env->vstart = 0 and might be reading vstart_eq_zero = false. This patch adds a new finalize_rvv_inst() helper that is called at the end of each vector instruction that will both update vstart_eq_zero and do a mark_vs_dirty().

2024-03-22target/riscv: remove 'over' brconds from vector transDaniel Henrique Barboza
All helpers that rely on vstart >= vl are now doing early exits using the VSTART_CHECK_EARLY_EXIT() macro. This macro will not only exit the helper but also clear vstart. We're still left with brconds that are skipping the helper, which is the only place where we're clearing vstart. The pattern goes like this: tcg_gen_brcond_tl(TCG_COND_GEU, cpu_vstart, cpu_vl, over); (... calls helper that clears vstart ...) gen_set_label(over); return true; This means that every time we jump to 'over' we're not clearing vstart, which is an oversight that we're doing across the board. Instead of setting vstart = 0 manually after each 'over' jump, remove those brconds that are skipping helpers. The exception will be trans_vmv_s_x() and trans_vfmv_s_f(): they don't use a helper and are already clearing vstart manually in the 'over' label. While we're at it, remove the (vl == 0) brconds from trans_rvbf16.c.inc too since they're unneeded.

2024-03-22target/riscv/vector_helpers: do early exit when vstart >= vlDaniel Henrique Barboza
We're going to make changes that will required each helper to be responsible for the 'vstart' management, i.e. we will relieve the 'vstart < vl' assumption that helpers have today. Helpers are usually able to deal with vstart >= vl, i.e. doing nothing aside from setting vstart = 0 at the end, but the tail update functions will update the tail regardless of vstart being valid or not. Unifying the tail update process in a single function that would handle the vstart >= vl case isn't trivial (see [1] for more info). This patch takes a blunt approach: do an early exit in every single vector helper if vstart >= vl, unless the helper is guarded with vstart_eq_zero in the translation. For those cases the helper is ready to deal with cases where vl might be zero, i.e. throwing exceptions based on it like vcpop_m() and first_m(). Helpers that weren't changed: - vcpop_m(), vfirst_m(), vmsetm(), GEN_VEXT_VIOTA_M(): these are guarded directly with vstart_eq_zero; - GEN_VEXT_VCOMPRESS_VM(): guarded with vcompress_vm_check() that checks vstart_eq_zero; - GEN_VEXT_RED(): guarded with either reduction_check() or reduction_widen_check(), both check vstart_eq_zero; - GEN_VEXT_FRED(): guarded with either freduction_check() or freduction_widen_check(), both check vstart_eq_zero. Another exception is vext_ldst_whole(), who operates on effective vector length regardless of the current settings in vtype and vl.

2024-03-22target/riscv: always clear vstart for ldst_whole insnsDaniel Henrique Barboza
Commit 8ff8ac6329 added a conditional to guard the vext_ldst_whole() helper if vstart >= evl. But by skipping the helper we're also not setting vstart = 0 at the end of the insns, which is incorrect. We'll move the conditional to vext_ldst_whole(), following in line with the removal of all brconds vstart >= vl that the next patch will do. The idea is to make the helpers responsible for their own vstart management. Fix ldst_whole isns by: - remove the brcond that skips the helper if vstart is >= evl; - vext_ldst_whole() now does an early exit with the same check, where evl = (vlenb * nf) >> log2_esz, but the early exit will also clear vstart. The 'width' param is now unneeded in ldst_whole_trans() and is also removed. It was used for the evl calculation for the brcond and has no other use now. The 'width' is reflected in vext_ldst_whole() via log2_esz, which is encoded by GEN_VEXT_LD_WHOLE() as "ctzl(sizeof(ETYPE))".

2024-03-22target/riscv: always clear vstart in whole vec move insnsDaniel Henrique Barboza
These insns have 2 paths: we'll either have vstart already cleared if vstart_eq_zero or we'll do a brcond to check if vstart >= maxsz to call the 'vmvr_v' helper. The helper will clear vstart if it executes until the end, or if vstart >= vl. For starters, the check itself is wrong: we're checking vstart >= maxsz, when in fact we should use vstart in bytes, or 'startb' like 'vmvr_v' is calling, to do the comparison. But even after fixing the comparison we'll still need to clear vstart in the end, which isn't happening too. We want to make the helpers responsible to manage vstart, including these corner cases, precisely to avoid these situations: - remove the wrong vstart >= maxsz cond from the translation; - add a 'startb >= maxsz' cond in 'vmvr_v', and clear vstart if that happens. This way we're now sure that vstart is being cleared in the end of the execution, regardless of the path taken.

2024-03-22target/riscv: do not enable all named features by defaultDaniel Henrique Barboza
Commit 3b8022269c added the capability of named features/profile extensions to be added in riscv,isa. To do that we had to assign priv versions for each one of them in isa_edata_arr[]. But this resulted in a side-effect: vendor CPUs that aren't running priv_version_latest started to experience warnings for these profile extensions [1]: | $ qemu-system-riscv32 -M sifive_e | qemu-system-riscv32: warning: disabling zic64b extension for hart 0x00000000 because privilege spec version does not match | qemu-system-riscv32: warning: disabling ziccamoa extension for hart 0x00000000 because privilege spec version does not match This is benign as far as the CPU behavior is concerned since disabling both extensions is a no-op (aside from riscv,isa). But the warnings are unpleasant to deal with, especially because we're sending user warnings for extensions that users can't enable/disable. Instead of enabling all named features all the time, separate them by priv version. During finalize() time, after we decided which priv_version the CPU is running, enable/disable all the named extensions based on the priv spec chosen. This will be enough for a bug fix, but as a future work we should look into how we can name these extensions in a way that we don't need an explicit ext_name => priv_ver as we're doing here. The named extensions being added in isa_edata_arr[] that will be enabled/disabled based solely on priv version can be removed from riscv_cpu_named_features[]. 'zic64b' is an extension that can be disabled based on block sizes so it'll retain its own flag and entry.

When we use qemu tcg simulation, the page size of bios is 4KB. When using the level 2 super huge page (page size is 1G) to create the page table, it is found that the content of the corresponding address space is abnormal, resulting in the bios can not start the operating system and graphical interface normally. The lddir and ldpte instruction emulation has a problem with the use of super huge page processing above level 2.

The low bit of MMU indices for x86 TCG indicates whether the processor is in 32-bit mode and therefore linear addresses have to be masked to 32 bits. However, the index was computed incorrectly, leading to possible conflicts in the TLB for any address above 4G.

The H_GUEST_RUN_VCPU hcall is used to start execution of a Guest VCPU. The Hypervisor will update the state of the Guest VCPU based on the input buffer, restore the saved Guest VCPU state, and start its execution. The Guest VCPU can stop running for numerous reasons including HCALLs, hypervisor exceptions, or an outstanding Host Partition Interrupt. The reason that the Guest VCPU stopped running is communicated through R4 and the output buffer will be filled in with any relevant state.

These wrappers call out to handle POWER7 and newer in separate functions but reduce to the generic case when TARGET_PPC64 is not defined. It is easy enough to include the switch in the beginning of the generic functions to branch out to the specific functions and get rid of these wrappers. This avoids one indirection and entirely compiles out the switch without TARGET_PPC64.
