0x31337000 -- 0x4097 -- NV40TCL
0x31337303 -- 0x39 -- NV_MEMORY_TO_MEMORY_FORMAT
0x3137C0DE -- 0x39 -- NV_MEMORY_TO_MEMORY_FORMAT
0x31337A73 -- 0x309E -- NV40_SWIZZLED_SURFACE
0x313371C3 -- 0x3062 -- NV40_CONTEXT_SURFACES_2D
0x3137AF00 -- 0x3089 -- NV40_SCALED_IMAGE_FROM_MEMORY
0x31337808 -- 0x308A -- NV40_IMAGE_FROM_CPU

Changelog:

• The [Install Other OS] and [Default System] features have been deleted.
• The playback quality of some PlayStation® format software that is downloaded (as a purchase or for free) from PlayStation®Store has been improved.
• A security patch was added to address security vulnerabilities that may occur when playing MP4 format video files.

I've been looking everywhere for a way to setup my own PS3 firmware bypass site because I really don't trust the one that everyone has been saying to use. I'd rather be sure my passwords, etc. are safe. Thanks!

Yeah, I am looking at it from another angle, and did not intend to following up on your point. It seems that hardware attacks in general challenge the very fundamentals of current generation consoles, and provide the last ingrediant in the "vulnerability cocktail" needed for a practical exploit. Therefore I am interested in how Sony decides to fix the underlying issues.

It should be no surprise if 3.21 is just a "quick fix". I only can imagine the QA people pulling their hair when the security people want to update the hypervisor and other relevant components to prevent glitching attacks. That sounds like a pretty complex task with a high risk for stability issues, compared to simply stripping out or just disabling OtherOS. It will be interesting to find out...

Did they in 3.21 also update the way the HV deallocates memory? (Which is a key weakness exploited by the PoC exploit) And what would be the performance hit of doing that as suggested in the tutorials? (extra verification)
