After more testing, I discovered that – unusually – the very latest driver (313.09) fails to compile with kernel 3.8-rc1, but an earlier driver – 310.14 – does compile OK! I won’t do too much more testing, as 3.8-rc1 breaks some KDE apps (see Linus’ angry rant on the LKML!). Hopefully 3.8-rc2 will be out soon.. Robert Gadsdon. … Continue reading →
Just updated the Dreamplug to 3.8-rc1, without any problems.. Used the .config from 3.7..

Just installed kernel 3.8-rc1 on my test system.. VMware 9.0.1 compiles and installs OK, with the 3.7 ‘softlink’ workaround: # ln -s /usr/src/linux-3.8-rc1/include/generated/uapi/linux/version.h /usr/src/linux-3.8-rc1/include/linux/version.h But… NVIDIA (313.09) compile fails, with a lot of errors: ………………../home/rgadsdon/NVIDIA-Linux-x86_64-313.09/kernel/conftest.h:10:2: error: #error remap_page_range() conftest failed! /home/rgadsdon/NVIDIA-Linux-x86_64-313.09/kernel/conftest.h:12:2: error: #error vmap() conftest failed! /home/rgadsdon/NVIDIA-Linux-x86_64-313.09/kernel/conftest.h:28:2: error: #error kmem_cache_create() conftest failed! /home/rgadsdon/NVIDIA-Linux-x86_64-313.09/kernel/conftest.h:30:2: error: #error on_each_cpu() conftest … Continue reading →
Linux was first developed by Linus on an old .386 system, way back in 1991, and now that cord has been cut, and .386 CPUs are no longer supported: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commit;h=743aa456c1834f76982af44e8b71d1a0b2a82e21 From the comments: Pull “Nuke 386-DX/SX support” from Ingo Molnar: “This tree removes ancient-386-CPUs support and thus zaps quite a bit of complexity: 24 files changed, 56 insertions(+), 425 deletions(-) … which complexity has plagued us with extra work whenever we wanted to change SMP primitives, for years. Unfortunately there’s a nostalgic cost: your old original 386 DX33 system from early 1991 won’t be able to boot modern Linux kernels anymore. Sniff.” I’m not sentimental. Good riddance. My first ‘home’ Linux system – in 1997 – was an HP Vectra 486 … Continue reading →
Just updated the Dreamplug kernel to 3.7, and – although I don’t use it – decided to see if the Marvell-supplied 8688_UAP (Access Point) patch still worked.. Not surprisingly, the patch worked, but the compilation failed: CC [M] drivers/net/wireless/libertas_uap/uap_main.o drivers/net/wireless/libertas_uap/uap_main.c: In function ‘uap_init_sw’: drivers/net/wireless/libertas_uap/uap_main.c:446:44: warning: passing argument 3 of ‘netlink_kernel_create’ makes pointer from integer without a cast … Continue reading →
Finally, kernel 3.7 is released… I updated my main x86_64 system, and all seems to be OK, as expected. The latest NVIDIA driver – 310.19 – compiles and runs OK, and VMware 9.0.1 compiles after the usual workaround for version.h: # ln -s /usr/src/linux-3.7/include/generated/uapi/linux/version.h /usr/src/linux-3.7/include/linux/version.h Note that this example is for the official source from kernel.org.

After the success of the Raspberry Pi, I have now updated the Dreamplug to Fedora 18, using yum…. This time, the rpm –import… worked fine, and the whole process went very smoothly..

As the Fedora 18 Beta had been stable on my x86_64 test system, I decided to update the Pi from F17 to F18.. As there is no ‘update’ image available, the only way is to use YUM.. Instructions are on the Fedora site: http://fedoraproject.org/wiki/Upgrading_Fedora_using_yum#Fedora_17_-.3E_Fedora_18 I found that the rpm –import command failed with a curl error: # … Continue reading →
The 3.6.y branch of the kernel on GitHub has now been updated to 3.6.9, in step with the ‘mainline’ kernel.. To get the source, you may need to explicitly reference the rpi-3.6.y.tar.gz download, instead of the (default) rpi-3.2.7.tar.gz https://github.com/raspberrypi/linux/archive/rpi-3.6.y.tar.gz Compilation was as described in earlier posts.. Fedora release 17 (Beefy Miracle) Kernel 3.6.9-pi on an armv6l (ttyAMA0) … Continue reading →
After a gap of over three months, there seems to be some activity with the APC kernel and uboot source on GitHub.. https://github.com/apc-io/apc-8750 Changes were made on December 2nd, but would appear to have been in error, for some reason, and the latest ‘commit’ is marked ‘Revert’.. The kernel version seems to have been the same, but … Continue reading →
