Subject: [PATCH] configure: Add linux header compile support for LoongArch
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
When compiling qemu with system KVM mode for LoongArch, header files
in directory linux-headers/asm-loongarch should be used firstly.
Otherwise it fails to find kvm.h on system with old glibc, since
latest kernel header files are not installed.
This patch adds linux_arch definition for LoongArch system so that
header files in directory linux-headers/asm-loongarch can be included.
Fixes: 714b03c125 ("target/loongarch: Add loongarch kvm into meson build")

Subject: [PATCH] hw/intc/loongarch_extioi: Add dynamic cpu number support
On LoongArch physical machine, one extioi interrupt controller only
supports 4 cpus. With processor more than 4 cpus, there are multiple
extioi interrupt controllers; if interrupts need to be routed to
other cpus, they are forwarded from extioi node0 to other extioi nodes.
On virt machine model, there is simple extioi interrupt device model.
All cpus can access register of extioi interrupt controller, however
interrupt can only be route to 4 vcpu for compatible with old kernel.
This patch adds dynamic cpu number support about extioi interrupt.
With old kernel legacy extioi model is used, however kernel can detect
and choose new route method in future, so that interrupt can be routed to
all vcpus.

Subject: [PATCH] hw/intc/loongarch_extioi: Add vmstate post_load support
There are elements sw_ipmap and sw_coremap, which is usd to speed
up irq injection flow. They are saved and restored in vmstate during
migration, indeed they can calculated from hw registers. Here
post_load is added for get sw_ipmap and sw_coremap from extioi hw
state.

Subject: [PATCH] hw/intc/loongarch_ipi: Use MemTxAttrs interface for ipi ops
There are two interface pairs for MemoryRegionOps, read/write and
read_with_attrs/write_with_attrs. The later is better for ipi device
emulation since initial cpu can be parsed from attrs.requester_id.
And requester_id can be overrided for IOCSR_IPI_SEND and mail_send
function when it is to forward message to another vcpu.

Subject: [PATCH] hw/loongarch/virt: Align high memory base address with super
page size
With LoongArch virt machine, there is low memory space with region
0--0x10000000, and high memory space with started from 0x90000000.
High memory space is aligned with 256M, it will be better if it is
aligned with 1G, which is super page aligned for 4K page size.
Currently linux kernel and uefi bios has no limitation with high
memory base address, it is ok to set high memory base address
with 0x80000000.

Subject: [PATCH] hw/loongarch/virt: Set iocsr address space per-board rather
than percpu
LoongArch system has iocsr address space, most iocsr registers are
per-board, however some iocsr register spaces banked for percpu such
as ipi mailbox and extioi interrupt status. For banked iocsr space,
each cpu has the same iocsr space, but separate data.
This patch changes iocsr address space per-board rather percpu,
for iocsr registers specified for cpu, MemTxAttrs.requester_id
can be parsed for the cpu. With this patches, the total address space
on board will be simple, only iocsr address space and system memory,
rather than the number of cpu and system memory.

v6.7.0-rc8
Use the scripts/update-linux-headers.sh to synchronize linux
headers from linux v6.7.0-rc8. We mainly want to add the
loongarch linux headers and then add the loongarch kvm support
based on it.

Subject: [PATCH] loongarch: Change the UEFI loading mode to loongarch
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The UEFI loading mode in loongarch is very different
from that in other architectures:loongarch's UEFI code
is in rom, while other architectures' UEFI code is in flash.
loongarch UEFI can be loaded as follows:
-machine virt,pflash=pflash0-format
-bios ./QEMU_EFI.fd
Other architectures load UEFI using the following methods:
-machine virt,pflash0=pflash0-format,pflash1=pflash1-format
loongarch's UEFI loading method makes qemu and libvirt incompatible
when using NVRAM, and the cost of loongarch's current loading method
far outweighs the benefits, so we decided to use the same UEFI loading
scheme as other architectures.

Subject: [PATCH] target/loongarch: Add loongarch kvm into meson build
Add kvm.c into meson.build to compile it when kvm
is configed. Meanwhile in meson.build, we set the
kvm_targets to loongarch64-softmmu when the cpu is
loongarch. And fix the compiling error when config
is enable-kvm,disable-tcg.

Timer emulation sometimes is problematic especially when vm is running in
kvm mode. This patch adds registers dump support relative with timer
hardware, so that it is easier to find the problems.

Implement kvm_arch_handle_exit for loongarch. In this
function, the KVM_EXIT_LOONGARCH_IOCSR is handled,
we read or write the iocsr address space by the addr,
length and is_write argument in kvm_run.

Subject: [PATCH] target/loongarch: Set cpuid CSR register only once with kvm
mode
CSR cpuid register is used for routing irq to different vcpus, its
value is kept unchanged since poweron. So it is not necessary to
set CSR cpuid register after system resets, and it is only set at
vm creation stage.

Subject: [PATCH] target/loongarch: Supplement vcpu env initial when vcpu reset
Supplement vcpu env initial when vcpu reset, including
init vcpu CSR_CPUID,CSR_TID to cpu->cpu_index. The two
regs will be used in kvm_get/set_csr_ioctl.

The kernel had already support LSX and LASX [1],
but QEMU is disable LSX/LASX for kvm. This patch adds
kvm_check_cpucfg2() to check CPUCFG2.
