Macbook Air 2013

I think we just decided to block the acpi interrupts caused by yosemite firmware through systemd service. Would be easier for those on an arch-only install. I wrote it in the post I linked just above yours. But that is a great update nonetheless! Thank you!

Anyone else have issues with multiple thunderbolt displays?

frank604 · 2015-01-30 17:52:00

As an update, the new yosemite update 10.10.2 resolved the gpe66 issue but gpe4E still going nuts. I have it disabled manually.

How did you guys fix :
[ +0.000005] ERROR @wl_cfg80211_get_tx_power : error (-1)
[ +1.194918] ERROR @wl_dev_intvar_get : error (-1)

It is constantly spamming in dmesg/journalctl. It is making my sdd active without rest. Anyone? I'm compiling some old kernels right now and will test some things out.

I tried building broadcom-wl with API=WEXT, built fine but doesn't load wl. I looked around but no solutions so far. How do you guys manage this? Or just live with it constantly writing to log?

Nvm, I figured out how to suppress. Damn that was annoying.

for everyone having the high cpu issue ,
just update to os x 10.10.2 , it has with the update a new firmware that fixes the issue for linux & windows ,
hope it help someone .

Is there any way to upgrade the firmware if we're using ArchLinux rather than OS X?

frank604 · 2015-02-01 03:10:55

I don't think that would be possible. At least the wiki says no https://wiki.archlinux.org/index.php/Ma … ating_OS_X
But tbh, I think it was perfectly fine with suppress services to systemd.

Did anyone update Intel processor microcode on Macbook Air early 2014 as per https://www.archlinux.org/news/changes- … deupdates/?

I used ReFind boot manager installed from iOS partition.

I used, BTW, amazingly easy installation guide differenet from Wiki one at http://dabase.com/blog/Macbook_Air_Earl … Archlinux/

After disableing gpe66 and gpe4E, installing powerdown, and tuning powertop, I can only get 5 hours of battery life, at best. While on mac OS X I get 9 hours.

What can be done ?

1. Try to update to the latest MacOs. There is hardware microcode update in one of the latest versions, to best of my knowledge.

2. Look at http://frankshin.com/category/macbook-air-2013/, he is doing some improvements to MBA overheating, which might be connected to your issue.

i have a problem with the screen going to sleep because of inactivity. i cannot get it back on.
the only solution besides a hard reset, is to close the lid and wait for the laptop to go to suspend mode, and only then if i open back the lid the screen come back to life.
i've installed mba6x_bl-dkms too, it helps for bightness being stuck to maximum when getting out of suspended mode.
i use xfce4.10, i tryed to set xfce power management to prevent putting the screen to sleep at all put it happens anyways, as if my settings are ignored.
anyone else is having this problem?
any idea what could be done ?

Is anyone else experiencing much lower battery life on 3.18.* than on 3.17.*?

On 3.17.6 I easily get about 11 hours, but under the same conditions (same brightness, usage, etc) I hardly get 5-6 hours.

Does anyone have any clues or ideas about this?

It's a bit hard for me to say, personally. I seem to be getting a bit lower battery life (~7hs), but I also feel that under 3.19 I've had my laptop under heavier load most of the time.

I'll try and run some tests making sure I'm under lighter load and get back to you.

regulament · 2015-03-06 21:02:03

On rMBP 11,2(15, Intel-only) and also having shorter battery life. From 6 hours down to 4( same usage).

Thanks, looking forward to your updates.

I haven't tried with 3.19 since I haven't enabled testing, but I might give it a try in the weekend.

So it looks like it's not just MBAs, but MBPs are affected as well..

Unfortunately, I'm no kernel dev and I have no idea where to start looking to find the cause of this in newer kernels.

I'll try searching in the kernel's bugzilla and also read some of the commit logs and see if I can figure anything out.

As to battery, I've been following this thread by graysky who felt that arch default kernel was having a poorer governance of cpu freq, more specifically on idle freqs. You can add graysky's ck repo and install his ck kernel (I've been using them for over a year). It has been on 3.19.0 since Feb 27. He's added some workarounds to the kernel compile config.

Personally, I work on very low workloads. So I just set my min/max cpu freq to 30% with no turbo so I am on a flat 800mhz. Of course when I do something that requires more oomph I'll revert to a 30/100 % cpu with turbo.

I'm still getting almost 1 hour per 10% battery on light usage (web for reading/forums & terminal with vim and mutt).

Thanks for the explanation, I'll try out graysky's ck kernel and report back if anything interesting happens.

That's slightly less than what I used to get with the stock kernel up until 3.17. (I used to get 11-12hs).

I've done a bit of testing with lighter load, and I can't get over 5hs. That's a huge regression.

Has anyone reported this upstream?

hobarrera · 2015-03-10 08:58:12

I've reported the issue in the Arch bug tracker: https://bugs.archlinux.org/task/44128

Feel free to contribute additional details if you feel they'll help.

Probably the fans, due to the extra heat.

it looks like another firmware issue that needs to be updated ,

because the issue also occur in windows too ( high temperature ) but not in mac ,

so my suggestion is this :

we report the issue to apple bug tracker & we all comment and contribute ,

because they will not fix any big unless it has some traction ( this is what happened whi the gpe66 issue ) .

so please let put our heads together and post the bug report .

If the issue isn't present when running different software, wouldn't that imply that it's the software at fault and not the firmware?
Also, the issue is supressed with linux <3.18, so that makes me think it's the firmware even less.

There's no way to upgrade the firmware from Arch anyway, so it'd be useless.

am at 3.10 lts & the problem is here ,

and sure all firmware updating is done through osx , what's the problem ?

In that case, you're having a different issue. With linux < 3.18, battery duration was ~11hs, and there was no overheat problem.

Uhm... I don't know if your trying to be funny, but this is an ArchLinux forum. We're ArchLinux users. If we can't install a certain firmware, then it's existence is pretty much useless to us.

that's what i meant by HEAT & NOISE in my first comment :

the laptop gets around 90 degree while watching a flash video & then the fans spin up 6000 rpm .

and NO am not trying to be funny , this is the Archlinux fourms about a thread talking about an apple laptop ,

and apple doesn't want you to run anything but osx , that's a given ,

if anything you are the one traying to be funny , you can't even update driver or BIOS in linux , that's also a given ,

so i don't see where the problem is or why am trying to be funny , am talking while these thoughts in my head .
