HWA Kernel for HD2

My kernel is based on Tytyung's r2.5 base
and mix the KGSL driver from Code Aurora

This is a DEV thread. the latest code may cause some problems.


HTC HD2 is still the KING!!!!


Notes:
1. this kernel can't be used in CM7 ROM
2. the current(before 27 Apr 2012) existing android4.0 ROMs can not directly use this kernel, becasue they are not using the correct libs to match the latest KGSL driver.

Update: 4 MAY 2012
Rick_1995 back port all the KGSL , MDP from 2.6.38 to tytung's 2.6.32 and the latest build can be found here: link
Update: 13 MAY 2012
Rick_1995 and tytung made some more progress : link

Update: 19 JUN 2012
Memory tweaks : link
msm: kgsl: Add support for the preamble context flag link

Update: 21 JUN 2012
backport the following items from the latest KGSL driver: link
msm: kgsl: let postmortem dump find context switch IBs
msm: kgsl: fix size checking in adreno_find_region
msm: kgsl: Set default value of wait_timeout in the adreno_dev struct
msm: kgsl: Make sure WPTR reg is updated properly
msm: kgsl: fix error handling in adreno_waittimestamp()
msm: kgsl: let postmortem dump find context switch IBs

22 JUN 2012 update link
msm: kgsl: remove readl/writel use for dma memory
msm: kgsl: convert sg allocation to vmalloc
msm: kgsl: Allocate physical pages instead of using vmalloc
msm: kgsl: make cffdump work with the MMU enabled
msm: kgsl: Add ION as an external memory source
msm: kgsl: Fixup per-process memory statistics
msm: kgsl: Make sure kmemleak tool does not report incorrect mem leak.
msm: kgsl: Add a new property to IOCTL_KGSL_DEVICE_GETPROPERTY
msm: kgsl: Poke regularly in adreno_idle
msm: kgsl: increase valid timestamp range
msm: kgsl: flush outer cache for alloc_page() pages
msm: kgsl: Add a constant for adreno_ringbuffer_issuecmds flags

Important Tips : don't turn on the Settings->Developer options-> Force GPU rendering
Turn on this option will cause problem.

23 JUN 2012 update link
change back the pmem size to 32MB adsp_pmem to 41MB this is the default configuration, It seems resolved the crash problem with DesireC GPU libs.

In this version I have already include the DesireC gpu libs in the zip file.
With the new GPU libs the Chrome Browser is very smooth, the hardware H.264 decoder is working.

25 JUN 2012 update
need more people to do the new GPU libs test link

25 JULY 2012 update link
1. ignore the version check in Qdsp6 Vdec which can prevent some crash when the vdec being used.
2. msm: kgsl: Write the retired timestamp on resume
3. msm: kgsl: handle larger instruction store for adreno225
4. msm: kgsl: Add support for the A3XX family of GPUs
5. reduced the PMEM_ADSP size as the HW decoder still can't work on HD2 (now we have 420MB memory for userspace)
6. msm: kgsl: Update the GMEM and istore size for A320
7. msm: kgsl: return correct error code for unknown ioctls
8. msm: kgsl: handle all indirect buffer types in postmortem
9. msm: kgsl: Detach memory objects from a process ahead of destroy time
10. msm: kgsl: Find a mem_entry by way of a GPU address and a pagetable base
11. msm: kgsl: Cleanup header file macros
12. msm: kgsl: Add GMEM size configuration in gpu list
13. msm: kgsl: don't clear gpuaddr when unmapping global mappings

Great thanks to Xylograph , dorimanx , Rick_1995, tytung and all of the guys who is reading this thread.

You mean you wont release it today :-(

I don't really get what you guys mean by "no kernel?" or "no release today?".

The code is there in a GIT repository and as far as I understood the OP the kernel is useless without a matching ICS/CM9 ROM anyways, so it makes no sense at all to release a binary and get flooded with "OMG IT DOES NOT WORK WITH CM7" replies.

If you think you know what to do with this kernel you should be able to set up GIT and a Android compile toolchain and compile it from source. If you need a flashable ZIP, this kernel is useless for you anyways.

This thread is dev/bug collection-related, not a kernel download thread. Wait for Xylograph to release his CM9.

Calm down people, none of the roms available yet use it anyway.

Xylograph in pm (removed few things)
Ok guys,
I think my beta build is amost finished and I will be leaving my workplace soon and go home..
I will be available again in about 4 hours from now to work on it again.. Will check XDA every once in a while..
Cheers !

I could post link to the alpha test rom we used, but it isn't that exciting with most stuff being buggy (some things even worse than current ics roms).

@securecrt, You have done what i was afraid of.. WHY WHY WHY overwrite git data with "first commit", if you had just used git push and git add remote, we could see what you had done without downloading the kernel.

@securecrt:
Congratulation that you have added HWA feature to the 2.6.32 kernel.
But I suggest that you may consider re-uploading another version including all the old commits and your changes.

Edit:
Or share your changes by executing "git diff > HWA.diff" or "git format-patch -o HWA.patch".

Hey tytung ;)

I created a diff of latest DORIMANX git and the HWA Kernel git.

Diff is available here https://www.dropbox.com/s/isv8ggyot1kzooa/DIFF-Dorimanx-HD2-2.6.32.X-SecureCRT-HD2-2.6.32.X-HWA.diff

I have a question, can i just take the "lib" directory from the CM9 ROM and add it to the AOKP build you made xlo? would that work? since they are both based off of CM9?

Tytung,

Please make a note that the securecrt kernel DOES work with usb tethering via the wired-tether 1.4 apk where your kernel does not. Perhaps this might help in debugging the issue? "normal" usb tethering brings up the rndis device (your kernel returns a -1 return code at that point) but fails to send or receive data...the wired tether apk gets around the issue and works as normal usb tether should.

If securecrt kernel makes wired-tether working, it should be that Dorimanx updated some code related to the USB driver. Or maybe the CM team updated CM9 (ICS 4.0.4) to make it compatible with old USB driver.

@securecrt:

Your kernel is awesome, but there's a small detail that jumps to the eye.
I was testing a CM9 rom based on your kernel, that as alot of banding on transparencies.

That defect was caught by Marc IIRC as a small value on the kernel that had to be changed.

Can you confirm this ?

    Please download the new file, as the previous verison didn't turn on the zram by default.

    I have included the zram(160MB swap disk) enable script in both of the zip, so just flash it and enjoy!

    ics & jellybean HWA kernel updates
    1. msm: kgsl: Change name of vmalloc allocator
    2. msm: kgsl: Map a guard page on the back of GPU MMU regions
    3. msm: kgsl: Optimize page_alloc allocations
    4.msm: kgsl: Add markers to identify IB sequence start and end
    5.msm: kgsl: rework ib checking
    jellybean
    1. include: checkout msm_mdp from ics_chocolate

    NOTES:
    1. the latest jellybean kernel can't work with Z880E GPU libs, I suggest to use DesireC GPU libs in jellybean ROMs
    2. the jellybean kernel can't work in ICS ROMs
    3. before flash the zip please replace the initrd.gz if you are not using NexusHD2 V2.5 ROM.
    4. the ICS kernel kgsl driver has been updated to very new version, even though the version number is still 3.8 but I have backport all the useful updates from 3.9 3.10 3.11, the further updates seems only works on jellybean.
