Run Win11 on ARM in QEMU

When following this guide on a host not capable of native arm64 KVM, replace -M virt -cpu host -accel kvm with -M virt,virtualization=on -cpu max.

The reason for virtualization=on is that the Windows bootloader does an smc #0 PSCI call, but without EL2, QEMU's TCG does not handle those because PSCI is in HVC mode and such that instruction is treated as undefined. With KVM enabled, smc #0 is handled properly.

Workaround in QEMU for using TCG without virtualization=on:

diff --git a/hw/arm/virt.c b/hw/arm/virt.c
index b871350856..de11ff51d1 100644
--- a/hw/arm/virt.c

Using KAGΣ (GPU rendered) with the macOS version of Kirikiri SDL2

  1. Compile Kirikiri SDL2 with -Denable_canvas=true
  2. Download a Chromium build from here: https://chromium.woolyss.com/
  3. Extract the Chromium archive
  4. Find the path of libEGL.dylib: find ~/Downloads/Chromium.app -name libEGL.dylib
  5. Find the path of libGLESv2.dylib: find ~/Downloads/Chromium.app -name libGLESv2.dylib
  6. Clone my fork of KAGΣ: git clone https://github.com/uyjulian/KAGSigma.git
  7. Run: SDL_VIDEO_EGL_DRIVER="/path/to/libEGL.dylib" SDL_VIDEO_GL_DRIVER="/path/to/libGLESv2.dylib" /path/to/krkrsdl2 /path/to/KAGSigma

Introduction

Here are some rough notes on building Kirikiri SDL2 for iOS and Android.
Please note that these may or may not be incomplete. Improved documentation is being planned, but not started yet.

Startup Directory selection

For iOS, the startup directory will be searched in <app name>.app/Contents/Resources/.
For Android, the startup directory will be searched in the root of the assets directory embedded in the apk. For best performance, the file should be stored uncomompressed.

Startup folder candidates:

What is CVE-2015-5672?

CVE-2015-5672 is a code execution exploit which can be used by specially-crafted savedata files. This exploit was reported to TYPE-MOON by Kazuhiko Kusano, but they did not release a patch because it is "difficult to solve with a new patch" (see section The fix for this security hole)

[IPv4 over IPv6 on Ubuntu] Solved the issue when connecting to archive.ubuntu.com takes too long. Edit /etc/gai.conf and uncomment line 4, which lets you keep IPv6 enabled, but sets the order of precedence to prefer IPv4 over IPv6. (http://askubuntu.com/a/354886) #tags: ubuntu, bittiger
#
# For sites which prefer IPv4 connections change the last line to
#
precedence ::ffff:0:0/96 100
