2024-06-08Hexagon: fix HVX store newMatheus Tavares Bernardino
At 09a7e7db0f (Hexagon (target/hexagon) Remove uses of op_regs_generated.h.inc, 2024-03-06), we've changed the logic of check_new_value() to use the new pre-calculated packet->insn[...].dest_idx instead of calculating the index on the fly using opcode_reginfo[...]. The dest_idx index is calculated roughly like the following: for reg in iset[tag]["syntax"]: if reg.is_written(): dest_idx = regno break Thus, we take the first register that is writtable. Before that, however, we also used to follow an alphabetical order on the register type: 'd', 'e', 'x', and 'y'. No longer following that makes us select the wrong register index and the HVX store new instruction does not update the memory like expected.

2024-06-08i386: Add support for overflow recoveryJohn Allen
Add cpuid bit definition for overflow recovery. This is needed in the case where a deferred error has been sent to the guest, a guest process accesses the poisoned memory, but the machine_check_poll function has not yet handled the original deferred error. If overflow recovery is not set in this case, when we handle the uncorrected error from the poisoned memory access, the overflow bit will be set and will result in the guest being shut down. By the time the MCE reaches the guest, the overflow has been handled by the host and has not caused a shutdown, so include the bit unconditionally.

2024-06-08target/i386: add support for FRED in CPUID enumerationXin Li
FRED, i.e., the Intel flexible return and event delivery architecture, defines simple new transitions that change privilege level (ring transitions). The new transitions defined by the FRED architecture are FRED event delivery and, for returning from events, two FRED return instructions. FRED event delivery can effect a transition from ring 3 to ring 0, but it is used also to deliver events incident to ring 0. One FRED instruction (ERETU) effects a return from ring 0 to ring 3, while the other (ERETS) returns while remaining in ring 0. Collectively, FRED event delivery and the FRED return instructions are FRED transitions. In addition to these transitions, the FRED architecture defines a new instruction (LKGS) for managing the state of the GS segment register. The LKGS instruction can be used by 64-bit operating systems that do not use the new FRED transitions. WRMSRNS is an instruction that behaves exactly like WRMSR, with the only difference being that it is not a serializing instruction by default. Under certain conditions, WRMSRNS may replace WRMSR to improve performance. FRED uses it to switch RSP0 in a faster manner. Search for the latest FRED spec in most search engines with this search pattern: site:intel.com FRED (flexible return and event delivery) specification The CPUID feature flag CPUID.(EAX=7,ECX=1):EAX[17] enumerates FRED, and the CPUID feature flag CPUID.(EAX=7,ECX=1):EAX[18] enumerates LKGS, and the CPUID feature flag CPUID.(EAX=7,ECX=1):EAX[19] enumerates WRMSRNS. Add CPUID definitions for FRED/LKGS/WRMSRNS, and expose them to KVM guests. Because FRED relies on LKGS and WRMSRNS, add that to feature dependency map.

2024-06-08i386/hvf: Updates API usage to use modern vCPU run functionPhil Dennis-Jordan
macOS 10.15 introduced the more efficient hv_vcpu_run_until() function to supersede hv_vcpu_run(). According to the documentation, there is no longer any reason to use the latter on modern host OS versions, especially after 11.0 added support for an indefinite deadline. Observed behaviour of the newer function is that as documented, it exits much less frequently - and most of the original function’s exits seem to have been effectively pointless. Another reason to use the new function is that it is a prerequisite for using newer features such as in-kernel APIC support. (Not covered by this patch.) This change implements the upgrade by selecting one of three code paths at compile time: two static code paths for the new and old functions respectively, when building for targets where the new function is either not available, or where the built executable won’t run on older platforms lacking the new function anyway. The third code path selects dynamically based on runtime detected availability of the weakly-linked symbol.

2024-06-08i386/hvf: In kick_vcpu use hv_vcpu_interrupt to force exitPhil Dennis-Jordan
When interrupting a vCPU thread, this patch actually tells the hypervisor to stop running guest code on that vCPU. Calling hv_vcpu_interrupt actually forces a vCPU exit, analogously to hv_vcpus_exit on aarch64. Alternatively, if the vCPU thread is not running the VM, it will immediately cause an exit when it attempts to do so. Previously, hvf_kick_vcpu_thread relied upon hv_vcpu_run returning very frequently, including many spurious exits, which made it less of a problem that nothing was actively done to stop the vCPU thread running guest code. The newer, more efficient hv_vcpu_run_until exits much more rarely, so a true "kick" is needed before switching to that.

2024-06-08i386/hvf: Fixes dirty memory tracking by page granularity RX->RWX changePhil Dennis-Jordan
When using x86 macOS Hypervisor.framework as accelerator, detection of dirty memory regions is implemented by marking logged memory region slots as read-only in the EPT, then setting the dirty flag when a guest write causes a fault. The area marked dirty should then be marked writable in order for subsequent writes to succeed without a VM exit. However, dirty bits are tracked on a per-page basis, whereas the fault handler was marking the whole logged memory region as writable. This change fixes the fault handler so only the protection of the single faulting page is marked as dirty. (Note: the dirty page tracking appeared to work despite this error because HVF’s hv_vcpu_run() function generated unnecessary EPT fault exits, which ended up causing the dirty marking handler to run even when the memory region had been marked RW. When using hv_vcpu_run_until(), a change planned for a subsequent commit, these spurious exits no longer occur, so dirty memory tracking malfunctions.) Additionally, the dirty page is set to permit code execution, the same as all other guest memory; changing memory protection from RX to RW not RWX appears to have been an oversight.

2024-06-08target/i386: fix SP when taking a memory fault during POPMark Cave-Ayland
When OS/2 Warp configures its segment descriptors, many of them are configured with the P flag clear to allow for a fault-on-demand implementation. In the case where the stack value is POPped into the segment registers, the SP is incremented before calling gen_helper_load_seg() to validate the segment descriptor: IN: 0xffef2c0c: 66 07 popl %es OP: ld_i32 loc9,env,$0xfffffffffffffff8 sub_i32 loc9,loc9,$0x1 brcond_i32 loc9,$0x0,lt,$L0 st16_i32 loc9,env,$0xfffffffffffffff8 st8_i32 $0x1,env,$0xfffffffffffffffc ---- 0000000000000c0c 0000000000000000 ext16u_i64 loc0,rsp add_i64 loc0,loc0,ss_base ext32u_i64 loc0,loc0 qemu_ld_a64_i64 loc0,loc0,noat+un+leul,5 add_i64 loc3,rsp,$0x4 deposit_i64 rsp,rsp,loc3,$0x0,$0x10 extrl_i64_i32 loc5,loc0 call load_seg,$0x0,$0,env,$0x0,loc5 add_i64 rip,rip,$0x2 ext16u_i64 rip,rip exit_tb $0x0 set_label $L0 exit_tb $0x7fff58000043 If helper_load_seg() generates a fault when validating the segment descriptor then as the SP has already been incremented, the topmost word of the stack is overwritten by the arguments pushed onto the stack by the CPU before taking the fault handler. As a consequence things rapidly go wrong upon return from the fault handler due to the corrupted stack. Update the logic for the existing writeback condition so that a POP into the segment registers also calls helper_load_seg() first before incrementing the SP, so that if a fault occurs the SP remains unaltered.

If the required DR7 (either from the VMCB or from the host save area) disables a breakpoint that was enabled prior to vmentry or vmexit, it is left enabled and will trigger EXCP_DEBUG. This causes a spurious #DB on the next crossing of the breakpoint. To disable it, vmentry/vmexit must use cpu_x86_update_dr7 to load DR7. Because cpu_x86_update_dr7 takes a 32-bit argument, check reserved bits prior to calling cpu_x86_update_dr7, and do the same for DR6 as well for consistency.
