Michael Scire 20ae7f3037 fs.mitm: add and use memlet module to temporarily steal applet memory while building romfs images. ... Starting in 20.0.0, the browser needs more applet memory to function, so we can't steal as much any more. Thus, we now steal 14 MB on 20.0.0+ instead of 40MB. However, since this reduces memory available for custom system modules, we are adjusting to compensate. ams.mitm's heap size has been reduced from 32MB to 12MB (recovering 20MB). In addition, fs.mitm now uses a new mechanism for stealing memory from the applet pool while romfs is being built. On net, we are compromising: * Custom sysmodules lose memory available to them. On 19.0.0/AMS 1.8.0, there was 30 MB available for custom sysmodules. Stealing 14 MB instead of 40 MB, we lose 26 MB of that. Reducing ams.mitm's usage will gain us back 20. Nintendo also appears to...use 4 extra MB, in 20.0.0, from my test homebrew. So on 20.0.0/AMS 1.9.0, there should be 20 MB available for custom sysmodules. On the bright side, on <20.0.0/AMS 1.9.0, I guess there will be 50 MB available for custom sysmodules now? * totk mods will lose the ability to...put every file in the romfs on sd card. There will be some unknown maximum filecount for totk mods. On the bright side, implementing the transient memory stealing should improve compatibility for some mods which strictly add files?		2025-05-09 12:10:10 -07:00
