[offtopic] ubuntu 12.10

Nouveau doesn’t work on macpro.

Cool update guys, going right way ! ….highway to hell…..

10.6.3 OpenGL regressions.

Phoronix posted interesting article about opengl performance decreases in 10.6.3 comparing to 10.6.2.

Just one graph from there:
result

It’s nvidia 9400m.

PCEFI V9, updated

This is new bootloader with few nice features, it’s n0w based on Chameleon codebase.

so, it supports all what Chameleon supports ( including /Extra)

and it has few new patches applied:

1) dsdt overwrite patch from mackerintel

2) resume from hibernate(aka deep sleep) support from me

(-nowake boot option to bypass resume, if u dont want it on current boot)

3) 64-bit kernel loading support from me  ( -x64 boot option to tell it to boot 64-bit kernel (only snow leo kernel has 64-bit part)

4) it supports new Extension.mkext location as in new snow leo

Now few words about hibernate, to activate it u can use e.g. this widget – deepsleep.free.fr

Bootloader will check /var/vm/sleepimage, and if it has proper signature, it will try to resume system

Now about problems, some systems fails to go to deepsleep state(e.g. gigabyte, asus), it’s caused by RTC bug in dsdt

to fix it – use fassl’s dsdt patcher, it will create proper dsdt.aml, rename it to DSDT.aml and put it in root of your partition

Find it here – http://forum.insanelymac.com/index.php?showtopic=133683

Also on radeon hd cards, after waking up from deepsleep, you will have only 1/4 of screen visible.

Bootloader – Bootloader

Improved messages about problems in sleepimage and will not try to resume with encrypted sleepimage(uncheck “use secure virtaual memory” in system preferences to fix it)

You also can use this bootloader with chameleon’s boot0/boot1h just fine.

as for source patch – as soon as I will clean it.

notice – if pc goes to regular sleep instead of deep sleep, and rtc dsdt fix didnt help – then probably deep sleep will not work on ur machine.

CPU-X:cpu-z like cpu detector for Mac OS X

Here is new app I made last week.

It’s designed to detect cpu capabilities and parametrs and show it in

cpu-z like maner.

information about freqs is continuously updated.

here it is :

UPDATED, now it will show if intel virtualization technology, aka VMX available(parallels4 needs it)

and removed mmx info, since every cpu has it.

and screenshot

cpuz sshot

supports only intel core 2 family cpus.

PC_efi brings leopard to atom(R).

One of our anonymous sources managed to run Leopard on atom based system he got.

Atom cpu has ssse3 and 64-bit, so it runs unmodified osx leopard kernel with efi emulator.

Detailed specs is:

northbridge: 945gc
CPU : Atom 1.6 Ghz
sound chip: ALC662
network RTL8102EL

512 MB RAM

osx missdetects cpu cache size, but it’s only cosmetic, not performance hits because of it

Here is some screenshots of tests which shows atom performance with osx.

xbench

geekbench 1.0 32-bit - 84.7 points

geekbench 1.0 64-bit - 90.8 points

“The machine could perform better with more RAM memory”

So you can see what performance will have atom based apple portable macs.

oh, and btw, this thing could run of a solar panel

UPDATE 

here some techincal info from system:

hw.ncpu = 2
hw.cpufrequency = 1600000000
hw.cpu64bit_capable: 1
hw.cpusubtype: 4
hw.cputype: 7
hw.logicalcpu: 2
hw.physicalcpu: 1
machdep.cpu.features: FPU VME DE PSE TSC MSR PAE MCE CX8 APIC SEP MTRR PGE MCA CMOV PAT CLFSH DS ACPI MMX FXSR SSE SSE2 SS HTT TM SSE3 MON DSCPL TM2 SSSE3 CX16 TPR PDCM
machdep.cpu.brand_string: Intel(R) Atom(TM) CPU 230 @ 1.60GHz

so it looks like Atom uses hyperthreading.

Some info about MacPro’s 2600XT and possible powerplay support.

it maybe usefull information for owner of radeonhd 3800/2600 card with overheating problem.

after digging a bit i managed to open 2600XT mapro’s bios image in Radeon Bios Editor

(google://RBE.exe)

and here is screenshot about supported state (which is for powerplay)

so idea is to try to edit Mhz for 2d state. good luck

Do it on your own risk.
