Mac Enablement Notes

This page contains notes regarding the kernel team's effort to enable a sampling of Apple hardware.

Mac Mini 5,2 (CID 201112-10198)

CPU: Intel Core i5-2520M (SandyBridge) @ 2.50GHz, 2 cores x 2 threads
Memory: 4 GB
Storage: TOSHIBA MK5065GS
Graphics: ATI Technologies Inc NI Whistler [AMD Radeon HD 6600M Series] [1002:6741]
Audio: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller [8086:1c20]
LAN: Broadcom Corporation NetXtreme BCM57765 Gigabit Ethernet PCIe [14e4:16b4]
WLAN: Broadcom Corporation BCM4331 802.11a/b/g/n [14e4:4331]
SD Host Controller: Broadcom Corporation NeXtreme BCM 57765 Memory Card Reader [14e4:16bc]
Firewire: Texas Instruments XIO2213A/B/XIO2221 IEEE-1394b OHCI Controller [Cheetah Express] [104c:823f]

Sometimes hangs when trying to suspend (s3) or resume from suspend, not yet sure which.
- Bug in broadcom wireless driver, now fixed in precise.
Broadcom wireless driver (b43) does not support 802.11n for the chipset used in this machine.

CPU: Intel Core i7-2677M (SandyBridge) @ 1.80GHz, 2 cores x 2 threads
Memory: 4 GB
Storage: 120 GB SSD
Graphics: Intel HD 3000 [8086:0116]
Audio: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller [8086:1c20]
WLAN: Broadcom Corporation BCM53224 802.11a/b/g/n [14e4:4353]

Power usage is high, about 10.5 to 11 W on average on an idle desktop. Enabling RC6 support in the i915 driver saves about 3 W, while the pm-utils changes currently being tested shave off another 1 W.
- This has improved during precise development. Now in the 7 W range so long as RC6 is enabled.
Display artifacts are seen from time to time.
- Has improved during precise development, I'm no longer noticing these.
Wireless cannot use DFS frequencies in 5 GHz band
- Workaround: Set regulatory domain manually

Sometimes hangs trying to suspend (s3). This is being caused by the radeon driver.
- Now fixed in precise.
Screen flickers after LVDS panel is turned off and back on. Being tracked on https://bugs.freedesktop.org/show_bug.cgi?id=44955.
- Now fixed in precise.
When machine is resumed from S3 without AC power applied, the wireless becomes unable to associate with any networks. Reloading b43 fixes the issue.
802.11n is not yet supported with this wireless chipset (b43 lacking 802.11n support with HT phy).
Power draw is excessive when using the radeon driver, ~30 W on an idle desktop. Drops to ~15 W with fglrx. According to upstream devs the power management support in radeon just isn't on par with fglrx at this point.
Cannot adjust display brightness. Support is available using various versions of gmux support available online.
Gain on internal microphone is extremely low, even when set to max volume using sound settings.
