[MS] Why is there no Windows hot-patching support for other architectures like 32-bit ARM and MIPS? - devamazonaws.blogspot.com
Windows hot-patching supports x86-32 , x86-64 , 64-bit ARM , and Itanium , but why not the other architctures like 32-bit ARM, MIPS, Alpha AXP, PowerPC, and SH-3? These architectures fall into two buckets. MIPS, Alpha AXP, PowerPC, and SH-3 all predate hot-patching, so they naturally couldn't conform to rules that didn't exist yet. Meanwhile, 32-bit ARM support was introduced¹ to Windows in the Windows 8 era, and at that time, hot-patching had already existed. But there were no provisions for hot-patching 32-bit ARM binaries because hot-patching is a Windows Server feature. Since there was no version of Windows Server for 32-bit ARM, there was no need to support hot-patching on 32-bit ARM binaries. ¹ More accurately, re -introduced, since Windows CE supported 32-bit ARM as well.
