12″ PowerBook G4 PT5 – Electronic Battle Weapon

Preparation for a trip started off a little earlier this christmas. I planned to take my PowerBook on the road with me to Hamburg for 33c3. Previous attempts to use this machine as my primary system on the road in the past had been thwarted by leaving too little time to build & prepare before departure.
The system has been dual booting NetBSD & Mac OS X Tiger for some time now, recently I’ve been doing almost daily upgrades to NetBSD-HEAD on the system using the generated iso images from NYFTP.
My plan was to get the machine installed with a current build FireFox on NetBSD & bring the existing installed packages up to date. I managed to update the existing packages without any problems but it didn’t look like FireFox was going to build successfully. The package as-is currently in pkgsrc does not build on NetBSD/macppc. I was pointed to a patch in pkg/48595 which was pending commit and required testing. It cleared up the initial issue I ran into but the build still failed (see previous link on updates about the failure), though it took a little longer to fail in the day. After several days of failed build attempts I made sure I had an up to date copy of TenFourFox installed on Tiger and settled for Dillo on NetBSD instead.

My usage of Dillo stayed somewhat basic during the trip, despite having the Mozilla certificate bundle installed, I could see any obvious way to point Dillo to it & have it use it. Hence, any site using SSL I visited generated a certificate warning. Perhaps the config should’ve been done in wget?

Alexander Nasonov created packages for Dillo & Links-gui targeted for running under a minimal chroot but I did not get around to trying them out. There are chrooted browser packages for other browsers in his pkgsrc github repo. The screenshot above shows the www/dillo package’s dependencies, generated using pkgtools/pkgdepgraph

Moving on, the AirPort Extreme card in the laptop is based on a Broadcom chipset which has a flaw, it’s incapable of addressing memory above 1GB (30 bits) which means the driver needs to care for that or else the card doesn’t work. This is not unique to this Broadcom chipset, the BCM4401 10/100 ethernet interfaces which use the bce(4) driver also suffer from the same problem (unable to address memory allocated above 30 bits), the BCM580x ethernet interfaces which use the bge(4) driver suffer from not being able to address more than 40 bits. Going back to the wireless chipset, the bwi(4) driver which is used in the BSDs, originated from DragonFly BSD. This driver was put together by Sepherosa Ziehau using the documentation from a reversing effort in the Linux community. The bwi driver was then imported in to Free/Open/NetBSD and was eventually removed from DragonFly BSD. A new wireless subsystem was introduced in DragonFly which required change to drivers to work again and the bwi driver was never adapted. It now lives on in the other BSDs.

The version of bwi(4) driver came to NetBSD from OpenBSD, ported by Taylor R. Campbell back in 2009. At the time neither version of drivers could handle the 30 bit bug so you either ran with less than 1GB of RAM or used another card. In 2014 Stefan Sperling committed a workaround for this in OpenBSD. I wanted this fix in NetBSD so my wifi could also work & asked the NetBSD developers if such a change was appropriate in NetBSD. I was introduced to bus_dma(9) and the bus_dmatag_subregion() function, the bce(4) driver was my reference on how to use the function. Looked fairly straight forward, a single call this function and off you go, wasn’t too sure how it would fit into the bwi driver but I thought I’d have a go.

This was one of the things I was hoping to work on during my trip but It turned out to be the only thing I attempt. I happened to meet Stefan at 33c3 and we discussed the driver, the work around and the mighty days of the past when Damien Bergamini was hacking on the OpenBSD WiFi stack. In the OpenBSD driver Stefan had opted to deal with the issue of allocating memory in a specific region directly in the driver rather than adding a new interface to the kernel for  such a task so with a bit of thought about the past and a review of the driver, I was given a diff of the changes and suggestions about where I could start making changes.

I still don’t know yet if it’s possible to lift the changes from OpenBSD and apply them to the NetBSD version of the driver, because the DMA framework is different between the systems.
Partially implementing the change Stefan made without all the bounce buffers he’d added in the OpenBSD driver didn’t work and using the bus_dmatag_subregion() function didn’t work either. I pursued the bus_dmatag_subregion() path during 33c3 and didn’t get anywhere. At this point I started looking deeper in the system by looking at the implementation. It was at this point that I discovered this function was defined to EOPNOTSUPP on PowerPC based systems. No matter what I had tried with this function it was a waste of time^W^W^Wvaluable learning experience about keeping documentation up to date & consistent.

At this point I started looking into adding support for tagged subregions so I could make use of the function. The implementation is fairly simple, a public function for a developer to use which performs various tests and a private function which is called to deal with the memory allocation. Unfortunately there were some missing members from the data structure on the powerpc side of NetBSD which needed further investigation and I stopped there for the time being.

For the trip I relied on a tiny Realtek RTL8188CUS based wifi adapter to get me network access. The card worked on the 802.1x enabled SSID at 33c3 using wpa_supplicant(8) on NetBSD/maccppc.

The driver for this card is now enabled by default in the GENERIC config file for NetBSD/macppc along with a group of other drivers for USB peripherals.

Thanks to Stefan for his help and advice with the bwi driver and Alex for the chrooted browser packages! 🙂

12″ PowerBook G4 PT 4

Due to various factors, I’ve not had much of a chance to play with the PowerBook much this month, earlier this moth a follow up to PR/48740 happened, requesting feedback on new changes which had been committed that I’ve not had a chance to test yet.
One thing I did do tonight was to re-flash the SuperDrive with a RPC-1 firmware image which turns the DVD drive region-free.
The firmware images are hosted on MacBook.fr and cover Macs all the way back to G3’s.
Flashing was straightforward though I could only re-flash with the version currently on the drive. It was not possible to flash a newer stock or region-free image on the drive.
Aside from the firmware on the DVD drive, Mac OS also tries to enforce region locking, the Region X utility can reset the Mac OS related setting regarding content region.

12″ PowerBook G4 PT 3

Since I last posted about dealing with pkgsrc on my PowerBook earlier this week, a patch has been committed which solves the linker issue on lang/gcc45 along with another fix related to how stripping of binaries is handled on Darwin. Unfortunately PR/48740 mentioned gcc44 to 46 suffer from the same issue but the patch has not been applied to gc44 or 46, I’m waiting to hear back from the committer.
One thing I forgot to mention in the previous post is that there is another issue with build process for GCC. There appears to be a deadlock issue where sh sits there chewing up CPU & context switching, at this point, aborting the build with & restarting again allows the build to continue.
Attaching to sh with gdb does not give any further insight as to what’s going on 🙁

12″ PowerBook G4 PT 2

As I wrote the previous post, the PowerBook was attempting to compile lang/gcc48 from pkgsrc & since then I’ve still been attempting to build lang/gcc48 with varying levels of success which led me to branch out from trying to build GCC 4.8 to the other 4.x releases on pkgsrc.

In-between roasting the PowerBook I managed to obtain a re-writable CD, that allowed me to install OpenBSD on the PowerBook. Everything went smoothly apart from some bug with installer/documentation. The OpenBSD install was short-lived as I swapped the 5400RPM HDD for an 64GB SSD, the empty partition is there ready for reinstall but the GCC builds have consumed most of the time with the computer so I’ve not got around to reinstalling on the new disk.

The laptop is now running with 1.25GB of RAM which has made a big difference, more than the SSD did, though the change is mainly visible in the apple supplied application binaries e.g System Preferences or Activity Monitor which don’t bounce on the dock whilst loading, click & it’s there, running.
About This Mac 1.25GB RAM
Trying to install a newer version of GCC from pkgsrc has been quite painful, build attempts are taking up to 20+ hours before failing, depending on which languages / options are enabled.

I reverted to attempting to building with only C & C++ language support to speed up the time to success/fail. This reduced the build time down to 8-10 hours, it then became apparent (a little quicker) that all GCC 4.x releases in pkgsrc fail to build on Mac OS X Tiger.
GCC 4.4 was the easiest to fix as the only thing that prevented the build of the C/C++ language support was a space between the -I flag & the path to headers to include which caused the linker to complain, this issues is taken care of in lang/gcc47 & gcc48 but the fix wasn’t retroactively applied to previous releases.
Attempting to build with GCC 4.5 & newer revealed further issues.
Thanks to the maintainer of TigerBrew, Misty De Meo who was able to provide hints for issues that need to be addressed in-order to build a more recent version of GCC on Tiger, having gone through the same problems when adding support in TigerBrew.

I’m not sure how many iterations other builds use but on pkgsrc gcc is built with 3 iterations of tests where binaries generated are compared at each iteration. The tests would fail on the third iteration, forcing dwarf2 format for debug data allowed the tests to succeed. As the G4 is a 32-bit PowerPC CPU, the build then failed when it came to 64-bit binaries, disabling multilib support resolved this issue, the build then failed as the linker & assembler bundled with XCode 2.5 were too old & missing functionality. Bug 52482 covers this issue.

Apple provides updates as part of their open source initiative, cctools contain the as & ld sources but sadly with the move to intel & the startup of the Hackintosh scene Apple has made it a little difficult to build things, their first move was to stop generating the iso of Darwin builds & the documentation seems non-existent now. Funnily enough the legacy information on the iPhone jailbreak & Hackintosh scene seems to be the commonly available documentation, that is ofcourse after you’ve excluded bug reports from fink & mac/darwinports in your search results. The main problem with building the open-source components is the bespoke build mechanism which seems to have various issues with Mac OS X, mainly missing header files, with TigerBrew, they seem to work around this issue by using the headers from a newer version of OS X. Through my search for a solution I discovered the OpenDarwin project, the project repackaged the source for the open source Apple components around the GNU toolchain. A version is available in pkgsrc in emulators/darwin_lib though it’s intended for NetBSD/PowerPC to provide binary compatibility, sadly the version it attempts to build is older than the version available with XCode 2.5. The OpenDarwin site is broken & the project doesn’t appear to be in development but I was able to find a repository on Apples MacOS Forge for the OpenDarwin cctools which contained the cctools-758. This was sufficient to allow GCC 4.x to build successfully, AS & AS_TARGET variables need to be set to where the new version of as(1) installed from odcctools however. GCC 4.7 built successfully with C, C++, Fortran, Objective C, Objective C++ & Fortran support. The code is in a SVN repository, you can obtain precompiled binaries of old versions of svn from collab.net.

While attempting to get things to build, lang/gcc48 was updated in pkgsrc and languages were separated out to individual packages with gcc48 becoming a wrapper around this, these changes are very much in their infancy and have issues which need to be addressed. As it currently stands, it’s not possible to build individual languages as there is ties which need to be removed e.g attempting to build lang/gcc48-cc++ will build in lang/gcc48-fortran. For me, the next step is to get these changes prepared correctly & submitted for inclusion in pkgsrc, for the duration of getting things to run I hard coded the paths for as(1) & defined the configure arguments globally, where as these changes are specific to Tiger & prior / 32-bit PowerPC specific. Then there’s dealing with odcctools, I’m not sure if it will require a new package or emulators/darwin_lib should be extended. emulators/darwin_lib introduces more than just odcctools hence my leaning towards a separate package. I also want to try out building from a RAM disk using Make RAM disk to see if build can be sped up any further. Since I wrote the previous article I found out how to set the location in F.lux, thanks to co-developer of F.lux, Michael Herf

It seems that some people opt to cross-compile for OS X on another platform, including macports developers (sorry, I didn’t make a note of the bug report where the developer explained building packages on Linux). iTerm 0.10 from the original project is now my terminal emulator with the Inconsolata font, the font smoothing isn’t that great on this machine when using white text on black background so I’ve opted for the opposite here & it’s working out well.
There is a MAC POWERPC ? blog which provides regular articles. I found an article on how to rebuild the PowerBook battery with new cells if it should fail.

Following the instructions from floodgap.com to update the curl-ca-bundle bundled with OS X I discovered that the version included in Tiger was from 2000!!

12″ PowerBook G4

PowerBook G4
With the talk on Twitter & App.net about old computers I started to get nostalgic. I had cleared out most of my collection back in 2012 & been resisting the urge to resume hoarding again largely, having successfully put off the purchase of a Ubiquiti EdgeRouter Lite to run FreeBSD on, I remembered that I was offered a G4 PowerBook a few months back which I turned down. It was still available if I wanted to take it, which made very happy. a 12″PowerBook6,4 that I’d assumed it was going to be a 15″ model. I’ve been playing about with it for the past couple of days, wiping the pre-installed copy of Leoapard & going through the Panther to Tiger path.

The system is now running 10.4.11, patching was a lot of fun, java update after java update, pretty sure it didn’t seem that bad at the time.
It was interesting to see that there was no iTunes update made available, having to manually fetch v9.2.1 from kb DL1056. Safari was updated to v4.1.3.

With no more updates on offer from the software update facility I disabled the java & macromedia plugins by moving them out of /Library/Internet Plug-ins & /Library/Application Support.

Going back to Tiger was a mixture of pleasure & pain, visually, I much prefer the brighter white look of aqua, as opposed to the grey theme which introduced in Leopard. Terminal.app in Tiger is not that great, font smooth is particularly poor, I may have to resort to sourcing a copy of the original iTerm. Plan9 from userspace built without issues using gcc from XCode 2.5, but I guess finder doesn’t like something about the bundled transparent icon of Glenda on the dock as it shows up with a white background & though acme launches correctly, the icon continues to bounce on the dock.
F.lux 1.1 is the last supported PowerPC build which runs on Tiger, no support for UK in location settings of this build.
TenFourFox takes the place of Firefox as an up to date, maintained version for the PowerPC Mac’s. Python was updated to 2.7.6 using a package straight from python.org.

There is a PowerPC Software site, which contains links to the last builds of popular software which supported the PowerPC Mac’s.

Mercurial & Ruby built successfully from source, pkgsrc also bootstrapped without any issue, the system is currently building GCC 4.8 from pkgsrc.
Needed to declare MACOSX_DEPLOYMENT_TARGET=10.4 otherwise the build process would fail with ld: flag: -undefined
dynamic_lookup can't be used with MACOSX_DEPLOYMENT_TARGET environment
variable set to: 10.1

The system currently has 512MB of RAM & a 74GB HDD, 40GB allocated to OS X & the remaining intended for use with OpenBSD, will have to netinstall OpenBSD as I don’t have any blank CD’s with me, no USB hub, the USB ports don’t provide sufficient power to run a Zalman Virtual CD and I suspect the system is unable to boot from USB anyway. Been looking on Amazon for IDE SSD drives but probably will increase the RAM first.
