+[BUG] cxl,i386: e820 mappings may not be correct for cxl
+
+Context included below from prior discussion
+    - `cxl create-region` would fail on inability to allocate memory
+    - traced this down to the memory region being marked RESERVED
+    - E820 map marks the CXL fixed memory window as RESERVED
+
+
+Re: x86 errors, I found that region worked with this patch. (I also
+added the SRAT patches the Davidlohr posted, but I do not think they are
+relevant).
+
+I don't think this is correct, and setting this to E820_RAM causes the
+system to fail to boot at all, but with this change `cxl create-region`
+succeeds, which suggests our e820 mappings in the i386 machine are
+incorrect.
+
+Anyone who can help or have an idea as to what e820 should actually be
+doing with this region, or if this is correct and something else is
+failing, please help!

+[Qemu-devel] [BUG/RFC] INIT IPI lost when VM starts
+
+Hi,
+We encountered a problem that when a domain starts, seabios failed to online a 
+vCPU.
+
+After investigation, we found that the reason is in kvm-kmod, KVM_APIC_INIT bit 
+in
+vcpu->arch.apic->pending_events was overwritten by qemu, and thus an INIT IPI 
+sent
+to AP was lost. Qemu does this since libvirtd sends a ‘query-cpus’ qmp command 
+to qemu
+on VM start.
+
+In qemu, qmp_query_cpus-> cpu_synchronize_state-> kvm_cpu_synchronize_state->
+do_kvm_cpu_synchronize_state, qemu gets registers/vcpu_events from kvm-kmod and
+sets cpu->kvm_vcpu_dirty to true, and vcpu thread in qemu will call
+kvm_arch_put_registers if cpu->kvm_vcpu_dirty is true, thus pending_events is
+overwritten by qemu.
+
+I think there is no need for qemu to set cpu->kvm_vcpu_dirty to true after 
+‘query-cpus’,
+and  kvm-kmod should not clear KVM_APIC_INIT unconditionally. And I am not sure 
+whether
+it is OK for qemu to set cpu->kvm_vcpu_dirty in do_kvm_cpu_synchronize_state in 
+each caller.
+
+What’s your opinion?
+
+Let me clarify it more clearly. Time sequence is that qemu handles ‘query-cpus’ qmp 
+command, vcpu 1 (and vcpu 0) got registers from kvm-kmod (qmp_query_cpus-> 
+cpu_synchronize_state-> kvm_cpu_synchronize_state->
+> do_kvm_cpu_synchronize_state-> kvm_arch_get_registers), then vcpu 0 (BSP) 
+sends INIT-SIPI to vcpu 1(AP). In kvm-kmod, vcpu 1’s pending_events’s KVM_APIC_INIT 
+bit set.
+Then vcpu 1 continue running, vcpu1 thread in qemu calls 
+kvm_arch_put_registers-> kvm_put_vcpu_events, so KVM_APIC_INIT bit in vcpu 1’s 
+pending_events got cleared, i.e., lost.
+
+In kvm-kmod, except for pending_events, sipi_vector may also be overwritten., 
+so I am not sure if there are other fields/registers in danger, i.e., those may 
+be modified asynchronously with vcpu thread itself.
+
+BTW, using a sleep like following can reliably reproduce this problem, if VM 
+equipped with more than 2 vcpus and starting VM using libvirtd.
+

+Where exactly is KVM_APIC_INIT dropped?  kvm_get_mp_state does clear the

+Fields that can be asynchronously written by other VCPUs (like SIPI,
+NMI) must not be SET if other VCPUs were not paused since the last GET.
+(Looking at the interface, we can currently lose pending SMI.)
+
+INIT is one of the restricted fields, but the API unconditionally
+couples SMM with latched INIT, which means that we can lose an INIT if
+the VCPU is in SMM mode -- do you see SMM in kvm_vcpu_events?
+
+Thanks.

+[BUG] accel/tcg: cpu_exec_longjmp_cleanup: assertion failed: (cpu == current_cpu)
+
+It seems there is a bug in SIGALRM handling when 486 system emulates x86_64 
+code.
+
+This code: 
+
+#include <stdio.h>
+#include <stdlib.h>
+#include <pthread.h>
+#include <signal.h>
+#include <unistd.h>
+
+pthread_t thread1, thread2;
+
+// Signal handler for SIGALRM
+void alarm_handler(int sig) {
+    // Do nothing, just wake up the other thread
+}
+
+// Thread 1 function
+void* thread1_func(void* arg) {
+    // Set up the signal handler for SIGALRM
+    signal(SIGALRM, alarm_handler);
+
+    // Wait for 5 seconds
+    sleep(1);
+
+    // Send SIGALRM signal to thread 2
+    pthread_kill(thread2, SIGALRM);
+
+    return NULL;
+}
+
+// Thread 2 function
+void* thread2_func(void* arg) {
+    // Wait for the SIGALRM signal
+    pause();
+
+    printf("Thread 2 woke up!\n");
+
+    return NULL;
+}
+
+int main() {
+    // Create thread 1
+    if (pthread_create(&thread1, NULL, thread1_func, NULL) != 0) {
+        fprintf(stderr, "Failed to create thread 1\n");
+        return 1;
+    }
+
+    // Create thread 2
+    if (pthread_create(&thread2, NULL, thread2_func, NULL) != 0) {
+        fprintf(stderr, "Failed to create thread 2\n");
+        return 1;
+    }
+
+    // Wait for both threads to finish
+    pthread_join(thread1, NULL);
+    pthread_join(thread2, NULL);
+
+    return 0;
+}
+
+
+Fails with this -strace log (there are also unsupported syscalls 334 and 435, 
+but it seems it doesn't affect the code much):

+Emulation of the same x86_64 code with qemu 6.2.0 installed on another x86_64

+486 host is pretty well out of support currently. Can you reproduce

+What compiler version do you build QEMU with? That
+assert is there because we have seen some buggy compilers
+in the past which don't correctly preserve the variable
+value as the setjmp/longjmp spec requires them to.

+It seems it only fails when the code is compiled for i486. QEMU built with the 
+same compiler with -march=i586 and above runs on the same physical hardware 
+without a problem. All -march= variants were executed on ryzen 3600.

+i486 and i586+ code variants were compiled with GCC 13.2.0 (more exactly, 
+slackware64 current multilib distribution).
+
+i486 binary which runs on the real 486 is also GCC 13.2.0 and installed as a 
+part of the buildroot crosscompiler (about two week old git snapshot).
