CDMA Verizon Touch Pro XIPs - WM6.5 Native Kernel 23047 23053

FormerPalmOS · #1 (**permalink**) 09-21-2009, 06:24 PM

Please see previous XIP thread here: http://forum.ppcgeeks.com/showthread.php?t=73316

These XIPs are in "old-style kitchen" format - ROM folder with os.nb.payload and boot.rgu in the ROM\XIP. I also have a romhdr.bin that should work with Visual Kitchen but I have not yet tested it.

I do not include WinCENLS - make sure this is in your SYS. Unless otherwise stated these are 12MB page pool, spinlock patched. I also include the no2chem GxDMA.dll wrapper for DDI. Make sure you don't duplicate GxDMA in your OEMDrivers.

These also include cachefilt.dll and some boot.hv tweaks to take advantage of that, and to remove some other generally useless stuff. I include the registry edits for the LockStream DRM package - removing this can cause you to get stuck in phone settings screen among other wierd problems.

EDIT 22-Sep - 23053 uploaded. Tested and booting. All seems well after a couple hours of playing. Made with PlatformRebuilder. Not quite as compact as the old way of doing it but not too bad either. ZIP includes entire ROM structure for Ervius Visual Kitchen - confirmed booting on VZW CDMA Touch Pro.

First up is 23047 tested and booting. Made with old-style touch, very compact, maximum memory recovery.

Massive huge thanks to Da_G and company for the CDMA Touch Pro WM6.5 native kernel.

Hurray~!!!!

For some reason, Visual Kitchen wants to re-allocate all the modules in my XIP, move things around and waste about 48KB of program memory. I've given up trying to straighten it out. On to see if I can actually get a booter...

Oh - and reserving this post in case I go past 5 attachments...

FPOS, do you have any threads on how you do this and the general theory behind it? is cachefilt just a filesystem filter? We have also found out that spinlock patching thr 6.5 NK yields worse performance or did you find a way around that? thanks! I love the work you do with the xip..

FPOS, how's the 6.5 NK in comparison to 6.1 after your tweak? I too have a Vzw TP and can't run 23053 due to lack of memory.

Um, is there even a kitchen out there that will build properly using xip.bin with a 6.5 NK? Pretty sure you need to use the VK or Platform Rebuilder, which don't use xip.bin.

Original post updated with CDMA Touch Pro XIP for SYS23053, AKU5 (WM6.5) native kernel nk.exe. Tested booting, all works. Includes cachefilt.dll. Answers to questions in above posts:

Somewhere I have a thread on Windows Mobile caching and file system performance. Basically yes cachefult.dll is a filter. What it does is smarter than diskcache.dll which is NOT a filter. Diskcache just reads the next few sectors when a request is made. If the next request happens to be captured by that read then you are golden. It keeps the last X amount of data read in memory (X is defined in boot.rgu - changing it elsewhere doesn't actually change anything - it must be defined in the XIP). Cachefllt is different - it reads the next n sectors that are part of the file, even if they aren't the next n sectors on the storage device. If those sectors are cached by diskcache.dll you are golden. If not, cachefilt.dll reads them (causing diskcache to do its thing again). The memory used for cachefilt.dll comes out of the pagepool. The memory used by diskcache comes out of program memory (you will see filesys.exe memory usage grow and shrink). Now all this said, diskcache.dll speeds up IMGFS reads. Cachefilt.dll does not. Cachefilt.dll ONLY speeds up reads to stuff that's NOT stored in ROM.

I have been running with a spinlocked nk.exe for a while and I can't say I notice an improvement or reduction in performance. I suspect the improvement is in latency, not raw throughput. I also spinlock several HTC OEM drivers and other files in the XIP - basically anything with the old-style ARM instructions.

23049 was the last AKU5 build I could run with the 6.1 kernel. 23053 has like 100 more modules and crushed the VM space on the 6.1 kernel. YOu have to move to 6.5. That said, 23053 hauls booty like a pimp driving a girls catholic school bus. So I'd have to say that the combination of 6.5 kernel and 23053 is for SURE the fastest combination I've seen yet, by a substantial margin. Possibly due to the number of modules, possibly due to actual MS improvements, or a combination of both.

Outside of PlatformRebuilder, there aren't really any XIP kitchens. I do it the old fashioned way. But once an xip.bin is build via any means possible, it is quite possible to have Visual Kitchen use that XIP instead of one created by Platform Rebuilder. If you comment out the XIP sections in the kitchen_build_rom.bat file in Ervius' visual kitchen, it won't touch the XIP. The back-end of visual kitchen is the same as all other kitchens - based on Maimach's IMGFS tools from way back when. The 2nd step is merging the os.nb.payload containing the XIP.bin with the os.nb generated from imgfs2nb and imgfsfromdump.

seems like 12 meg PagePool is too much for me. mostly because I'm using manila, voice command, pocketshield, push email... with everything loaded i get about 24 megs free... and it gradually goes down to nothing.

I have to get TP2.

EDIT: After i go through each of the tabs i get 15 megs free..
