[PATCH] powerpc: Lower threshold for DART enablement to 1GB

2006-04-21T12:29:37+00:00

Turn on the DART already at 1GB. This is needed because of crippled
devices in some systems, i.e. Airport Extreme cards, only supporting
30-bit DMA addresses.

Otherwise, users with between 1 and 2GB of memory will need to manually
enable it with iommu=force, and that's no good.

Some simple performance tests show that there's a slight impact of
enabling DART, but it's in the 1-3% range (kernel build with disk I/O
as well as over NFS).

iommu=off can still be used for those who don't want to deal with the
overhead (and don't need it for any devices).

[PATCH] powerpc: Fix some MPIC + HT APIC buglets

2006-02-24T00:36:37+00:00

Do disable, not enable, the HT APIC IRQ in the function that is
supposed to.
Enable the MPIC IRQ before enabling the downstream APIC IRQ, avoids
potentially losing an interrupt.

[PATCH] powerpc: trivial: modify comments to refer to new location of files

2006-02-10T05:53:51+00:00

This patch removes all self references and fixes references to files
in the now defunct arch/ppc64 tree.  I think this accomplises
everything wanted, though there might be a few references I missed.

[PATCH] powerpc: Always panic if lmb_alloc() fails

2006-02-07T11:38:34+00:00

Currently most callers of lmb_alloc() don't check if it worked or not, if it
ever does weird bad things will probably happen. The few callers who do check
just panic or BUG_ON.

So make lmb_alloc() panic internally, to catch bugs at the source. The few
callers who did check the result no longer need to.

The only caller that did anything interesting with the return result was
careful_allocation(). For it we create __lmb_alloc_base() which _doesn't_ panic
automatically, a little messy, but passable.

Cleaned up fsl_soc.c based on comments from Olof Johansson.  Ran through
Lindent, and split gfar_mdio init into its own function.

[PATCH] powerpc: Add FSL SOC library and setup code

2006-01-14T00:13:22+00:00

Parse the flat device tree for devices on Freescale SOC's that we know
about (gianfar, gianfar_mdio, i2c, mpc83xx_wdt).  We need to setup
platform devices and platform data for these devices to match arch/ppc
usage.

Also add a helper function (get_immrbase) that reports the base
address of the MMIO registers on the SOC.
