Load and start VSH's kernel modules before booting vshmain.prx A few flash0 modules (vshbridge.prx, paf.prx, common_gui.prx, common_util.prx) should run for real once we know we're actually booting the VSH rather than a game, since our fakes are unlikely to be good substitutes for the genuine thing.

// sceVshBridge is the HLE surface of flash0:/kd/vshbridge.prx, a kernel-mode module that
|
|
// exposes a bunch of otherwise-kernel-only functionality (controller reads, LoadExec
|
|
// variants, audio/ME/display bits, MagicGate memory stick audio, etc.) to the VSH, which
|
|
// mostly runs in user mode.
|

|
|
// Unlike sceVshCommonUtil/sceVshCommonGui, we intentionally only implement the handful of
|
|
// NIDs that genuinely need to trap into PPSSPP's own host-level code (controller input,
|
|
// process control, our own module-loading machinery) - the same reasoning that applies to
|
|
// every other kernel syscall PPSSPP HLEs for regular games. We now load and start the real
|
|
// vshbridge.prx as part of booting the VSH (see LoadAndStartVshKernelModules in
|
|
// sceKernelModule.cpp), so registering a stub for every other NID here would silently discard
|
|
// vshbridge.prx's real, working exports in favor of a placeholder that just logs an error -
|
|
// Core/HLE/sceKernelModule.cpp's ExportFuncSymbol() ignores a module's real export if we claim
|
|
// to already have HLE for that NID. Found this the hard way with sceVshCommonUtil first.
