Hi everyone,
First, read the readme.txt in the zip file.
You flash it at your own risk. Backup everything. Learn how to use Heimdall. If it eats your dog it's not my problem . Many things are broken - post about it in the thread if nobody posted before. If you have any idea how to fix things, post too or PM me.
Requirements: GSM (Euro, US ATT/TMO tabs), with JQ1 (Gingerbread) unprotected bootloaders that can run Euro JQ1 ROM and gt-p1000_mr.pit partitioning.
Modem versions:
ATT: use I9000UGJK3 modem (this is what I am using)
TMO: try JK5
Euro: reports say that JK5, JPZ modems work
HK: user reports JK5 modem works.
CDMA: This ROM does not support CDMA Tabs. KhasMek is working on CDMA version and he has released public test builds, get it here
http://rootzwiki.com/showthread.php?438-CM7-ALPHA-v1-Public-Release-0615
The archive with the build with Heimdall is here
http://gtab7.nexus-lab.com/cm7sgt/tcm7beta-2011-08-07.zip
Please use heimdall to install. This zip file is not for flashing with CWM. Please read the readme.txt in the zip file.
The update zip for CWM is here
http://gtab7.nexus-lab.com/cm7sgt/update-cm-7-2011-08-07-Beta-GalaxyTab-KANG-signed.zip, if you encounter any problems, use the Heimdall version.
P1000L/N
Humberos has created a kernel (repackaged binary with CM7 initramfs) that is available here
http://www.multiupload.com/CMDOXY8U88
P1000L/N users, please try it. Please note that this kernel is not built from sources so it may be missing kernel fixes, OC/UV, Voodoo Sound etc.
Please report bugs in his thread here ->
http://xdaforums.com/showthread.php?t=1124224
And send him thanks for his great work! (I suspect this kernel will not work with 2011-08-07 update, since it has old PowerVR kernel driver.)
If you get stuck on first reboot after install, or your settings aren't saved it means your data partitions need to be reformatted to ext4. This should be handled by setup_fs in init.rc.
If it didn't happen, start adb and run
make_ext4fs /dev/block/mmcblk0p2
make_ext4fs /dev/block/stl10
make_ext4fs /dev/block/stl11
Or try full wipe in recovery but that seems to have problems too (stuck at formatting android_secure).
make_ext4fs is slightly wonky so you could use "/system/bin/mke2fs -t ext4 -m 0" instead (recovery is also using make_ext4fs internally to wipe partitions)

How to report bugs
If you think you have found a bug.
- verify you can repeat it, make sure it is not caused by the fact you did not wipe the device by rebooting to recovery and using wipe when you first installed CM7. Particularly when coming from other ROMs that use ext4. When coming from RFS your partitions should have been reformatted on first boot but wiping after install will not hurt.
Please read existing open and already closed issues at
http://github.com/cm7sgt/android_device_samsung_galaxytab/issues
If your bug is new.
Please see if it is upstream (general CM7 not related to Tab) bug, see in CM7 issues tracker
http://code.google.com/p/cyanogenmod/issues/list
If it is already there, please stop or add a comment there.
If the bug is about generic issue, please try to verify it it also happens on other CM7 devices. If so, you should post it in CyanogenMod issues.
If the bug is Galaxy Tab specific, like, some hardware functionality is missing, some driver not working. Dialogs messed up because of resolution etc, this means it belongs to Galaxy Tab device issue tracer and I can fix it.
In this case please open new issue here
http://github.com/cm7sgt/android_device_samsung_galaxytab/issues
Please use pastie.org or something like that for posting logs.
SDCARD controversy
Your embedded MMC is /mnt/emmc, your external SD card is /mnt/sdcard.
Some of you are not happy with how the embedded MMC (/mnt/emmc) and external SD card (/mnt/sdcard) are mounted in my CM7 port. Since it is not possible to to make everyone happy, and my happiness is my priority, it will stay as it is.
If you want it the same way as Samsung set it up in their ROM, please use the attached modified vold.fstab created by Fabrizio. (thanks)
Unzip it, make sure adb is working, start your console
adb remount
adb push vold.fstab /system/etc
adb reboot
If someone will create update.zip for it I will attach it to first post too.

Changelog:
2011-08-07
Update to latest from git. Android 2.3.5.
Added BLN kernel driver and LIGHT_ID_NOTIFICATIONS -> /sys/class/misc/backlightnotification/notification_led device to liblights. Big thanks to Neldar.
Fix geolocation/networklocation settings in props and frameworks' config.xml
Update EGL driver and pvrsvrkm kernel driver to latest from EF17 Sprint GB release.
2011-07-20
Update to latest from git.
Merge changes from Sprint GB kernel source release. Merge relevant kernel changes to up to 2.6.35.10.
2011-06-21
Enable CRT screen off/on animation.
Add virtual flag to capacitive buttons to enable vibration when they are pressed.
Increase HCI baud rate to 3M, hopefully this will help A2DP issues with BT keyboards.
2011-06-13
Rotary Lockscreen bitmaps and Twelve Key Dialer portrait and landscape layouts have been fixed by Fabrizio. Big thanks!
Fixed wrong parameter to ril->setCallVolume, hopefully will make call audio better.
Switched to use Samsung's binary brcm_patchram_plus with the same parameters in init.rc. Bluetooth SCO works now. Magic?
2011-06-06
Add attribute for available frequencies, fix cpufreq sysfs permissions so CMParts can access it.
Change compile options for kernel to cortex-a8. Enable Tiny RCU.
Fixed calls from other places in the kernel that used olde speed levels and caused frequency spikes to 1.2GHz.
Fixed Low Power Mode (it properly starts /lpm.rc and displays charging animation).

Use JQ1 binary drivers for OpenGL, sensors, lights, copybit, overylay, camera etc, so they all work!
Portrait is default orientation now, ro.sf.hwrotation=90 is set and touchscreen events are rotated in input layer so they match.
<cut short, more in readme.txt>

How to build CYanogenMod 7 for Galaxy Tab GT-P1000
First, please read this article
http://wiki.cyanogenmod.com/index.php?title=Compile_CyanogenMod_for_CaptivateMTD
You will need the same prerequisites.
Then
Get repo as described there. I put mine in /usr/local/bin
Sync Android tree. You need to use manifest from cm7sgt github.
(If you have more/less than 4 cores modify your -j4 accordingly)
Create a directory for your Android, you will need oer 10GB of free space. It helps a lot to put it on SSD.
repo init -u git://github.com/cm7sgt/android.git -b gingerbread
repo sync -j4
Grab Rom Manager as described.
[ optional
Grab gapps. run vendor/cyanogen/get-google-files -v gb
then export CYANOGEN_WITH_GOOGLE=1
]
You can't (no script) and don't need to copy proprietary files, everything is already included in vendor git.
Setup your android build environment and choose device to build:
. build/envsetup.sh
lunch cyanogen_galaxytab-eng
make -j4
There, it should build with no issues. Sometimes it will complain about API changes, run make update-api then.
From here you have two options.
1. Build Heimdall images. You will need kernel with loop support, losetup, ext4 tools (mkfs.ext4).
cd device/samsung/galaxytab/tools
./buildimage
it will grab stuff from out and create ext4 images. Flash with Heimdall.
2. Build update.zip
make -j4 bacon
How to build kernel
First, you will need the arm toolchain from CodeSourcery. You need arm-2009q3-68-arm-none-eabi-i686-pc-linux-gnu.tar.bz2
From
http://www.codesourcery.com/sgpp/li...q3-68-arm-none-eabi-i686-pc-linux-gnu.tar.bz2
Unpack it in /opt/toolchains. as root
mkdir -p /opt/toolchains
cd /opt/toolchains
tar -xjvf arm-2009q3-68-arm-none-eabi-i686-pc-linux-gnu.tar.bz2
Then in your CM7 tree
BEFORE YOU BUILD CM7 TREE
cd device/samsung/galaxytab
./kernel.sh defconfig
./kernel.sh modules
This will configure the kernel and build and copy modules to prebuilt directories. The kernel build directory is out/target/product/galaxytab/kernel_build
Build your android tree normally so initramfs is created.
Then again
cd device/samsung/galaxytab
./kernel.sh kernel
This will build the kernel using the initramfs in recovery/root and update prebuilt kernel image.
Now you need to run make on your android tree again so boot.img is updated.
And proceed to buildimage or make bacon as usual.
