[PATCH] Adds filll word to dictionary
by Programmingkid Dec. 2, 2012

Dec. 2, 2012

The filll word fills a region of memory with a 4 byte value. This word is different from fill because fill is used to fill a region of memory with a 1 byte value. This word is needed by bootx to boot Mac OS X. Here are some test results comparing Apple's implementation to mine. Apple's implementation: 0 > 100 buffer: mybuffer ok 0 > mybuffer 100 87654321 filll ok 0 > mybuffer 100 dump ffbc8800: 87 65 43 21 87 65 43 21 87 65 43 21 87 65 43 21 |.eC!.eC!.eC!.eC!| ffbc8810: 87 65 43 21 87 65 43 21 87 65 43 21 87 65 43 21 |.eC!.eC!.eC!.eC!| ffbc8820: 87 65 43 21 87 65 43 21 87 65 43 21 87 65 43 21 |.eC!.eC!.eC!.eC!| ffbc8830: 87 65 43 21 87 65 43 21 87 65 43 21 87 65 43 21 |.eC!.eC!.eC!.eC!| ffbc8840: 87 65 43 21 87 65 43 21 87 65 43 21 87 65 43 21 |.eC!.eC!.eC!.eC!| ffbc8850: 87 65 43 21 87 65 43 21 87 65 43 21 87 65 43 21 |.eC!.eC!.eC!.eC!| ffbc8860: 87 65 43 21 87 65 43 21 87 65 43 21 87 65 43 21 |.eC!.eC!.eC!.eC!| ffbc8870: 87 65 43 21 87 65 43 21 87 65 43 21 87 65 43 21 |.eC!.eC!.eC!.eC!| ffbc8880: 87 65 43 21 87 65 43 21 87 65 43 21 87 65 43 21 |.eC!.eC!.eC!.eC!| ffbc8890: 87 65 43 21 87 65 43 21 87 65 43 21 87 65 43 21 |.eC!.eC!.eC!.eC!| ffbc88a0: 87 65 43 21 87 65 43 21 87 65 43 21 87 65 43 21 |.eC!.eC!.eC!.eC!| ffbc88b0: 87 65 43 21 87 65 43 21 87 65 43 21 87 65 43 21 |.eC!.eC!.eC!.eC!| ffbc88c0: 87 65 43 21 87 65 43 21 87 65 43 21 87 65 43 21 |.eC!.eC!.eC!.eC!| ffbc88d0: 87 65 43 21 87 65 43 21 87 65 43 21 87 65 43 21 |.eC!.eC!.eC!.eC!| ffbc88e0: 87 65 43 21 87 65 43 21 87 65 43 21 87 65 43 21 |.eC!.eC!.eC!.eC!| ffbc88f0: 87 65 43 21 87 65 43 21 87 65 43 21 87 65 43 21 |.eC!.eC!.eC!.eC!| My patch: 0 > mybuffer 100 87654321 filll ok 0 > mybuffer 100 dump fff771e0 87 65 43 21 87 65 43 21 87 65 43 21 87 65 43 21 ?eC!?eC!?eC!?eC! fff771f0 87 65 43 21 87 65 43 21 87 65 43 21 87 65 43 21 ?eC!?eC!?eC!?eC! fff77200 87 65 43 21 87 65 43 21 87 65 43 21 87 65 43 21 ?eC!?eC!?eC!?eC! fff77210 87 65 43 21 87 65 43 21 87 65 43 21 87 65 43 21 ?eC!?eC!?eC!?eC! fff77220 87 65 43 21 87 65 43 21 87 65 43 21 87 65 43 21 ?eC!?eC!?eC!?eC! fff77230 87 65 43 21 87 65 43 21 87 65 43 21 87 65 43 21 ?eC!?eC!?eC!?eC! fff77240 87 65 43 21 87 65 43 21 87 65 43 21 87 65 43 21 ?eC!?eC!?eC!?eC! fff77250 87 65 43 21 87 65 43 21 87 65 43 21 87 65 43 21 ?eC!?eC!?eC!?eC! fff77260 87 65 43 21 87 65 43 21 87 65 43 21 87 65 43 21 ?eC!?eC!?eC!?eC! fff77270 87 65 43 21 87 65 43 21 87 65 43 21 87 65 43 21 ?eC!?eC!?eC!?eC! fff77280 87 65 43 21 87 65 43 21 87 65 43 21 87 65 43 21 ?eC!?eC!?eC!?eC! fff77290 87 65 43 21 87 65 43 21 87 65 43 21 87 65 43 21 ?eC!?eC!?eC!?eC! fff772a0 87 65 43 21 87 65 43 21 87 65 43 21 87 65 43 21 ?eC!?eC!?eC!?eC! fff772b0 87 65 43 21 87 65 43 21 87 65 43 21 87 65 43 21 ?eC!?eC!?eC!?eC! fff772c0 87 65 43 21 87 65 43 21 87 65 43 21 87 65 43 21 ?eC!?eC!?eC!?eC! fff772d0 87 65 43 21 87 65 43 21 87 65 43 21 87 65 43 21 ?eC!?eC!?eC!?eC!

[PATCH] PPC: Rework assignment of keyboard devalias.
by Mark Cave-Ayland Dec. 1, 2012

Dec. 1, 2012

Rather than simply copy the value of input-device, we scan the device tree for an entry with a device_type of keyboard and use that. This ensures that the keyboard alias always points to a physical keyboard device.
