-[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.

-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.

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

-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).
