powerpc/ps3: Add empty repository highmem routines

2015-01-22T06:31:21+00:00

To avoid the need for preprocessor conditionals in C source files add a set of empty inline repository highmem write routines to platform.h that are used when CONFIG_PS3_REPOSITORY_WRITE is not defined. Signed-off-by: Geoff Levand Signed-off-by: Michael Ellerman

powerpc/ps3: Add highmem repository read routines

2012-04-24T22:34:17+00:00

Add repository helper routines to read highmem region info. Bootloaders that preallocate highmem regions must place the region info into the repository at these well known nodes. These routines allow second stage kernles to read the region info from those nodes. Signed-off-by: Andre Heider CC: Nathan Whitehorn Signed-off-by: Geoff Levand

powerpc/ps3: Add highmem repository write routines

2012-04-24T22:34:17+00:00

Add routines to allow Linux based bootloaders to create and/or modify highmem region info in the PS3 system repository where it can be retrived by later boot stages. Signed-off-by: Geoff Levand

powerpc/ps3: Fix lost SMP IPIs

2011-11-16T03:47:54+00:00

Fixes the PS3 bootup hang introduced in 3.0-rc1 by: commit 317f394160e9beb97d19a84c39b7e5eb3d7815a sched: Move the second half of ttwu() to the remote cpu Move the PS3's LV1 EOI call lv1_end_of_interrupt_ext() from ps3_chip_eoi() to ps3_get_irq() for IPI messages. If lv1_send_event_locally() is called between a previous call to lv1_send_event_locally() and the coresponding call to lv1_end_of_interrupt_ext() the second event will not be delivered to the target cpu. The PS3's SMP IPIs are implemented using lv1_send_event_locally(), so if two IPI messages of the same type are sent to the same target in a relatively short period of time the second IPI event can become lost when lv1_end_of_interrupt_ext() is called from ps3_chip_eoi().

powerpc/cell: Extract duplicated IOPTE_* to

2009-06-15T03:26:19+00:00

Both arch/powerpc/platforms/cell/iommu.c and arch/powerpc/platforms/ps3/mm.c contain the same Cell IOMMU page table entry definitions. Extract them and move them to , while adding a CBE_ prefix. This also allows them to be used by drivers. Signed-off-by: Geert Uytterhoeven Signed-off-by: Benjamin Herrenschmidt

powerpc/ps3: Add rtc-ps3

2009-04-02T01:05:32+00:00

Create a real RTC driver for PS3, and unhook the deprecated ppc_md.[gs]et_rtc_time. Signed-off-by: Geert Uytterhoeven Acked-by: Alessandro Zummo Acked-by: Geoff Levand Signed-off-by: Kyle McMartin

[POWERPC] PS3: Use the HVs storage device notification mechanism properly

2008-01-25T11:52:51+00:00

The PS3 hypervisor has a storage device notification mechanism to wait until a storage device is ready. Unfortunately the storage device probing code used this mechanism in an incorrect way, needing a polling loop and handling of devices that are not yet ready. This change corrects this by: - First waiting for the reception of an asynchronous notification that a new storage device became ready, - Then looking up the storage device in the device repository. On shutdown, the storage probe thread is stopped and the storage notification device is closed using a reboot notifier.

[POWERPC] PS3: Add ps3_repository_find_device_by_id()

2008-01-25T11:52:51+00:00

The storage probe feature of the PS3 hypervisor returns device IDs. Add the corresponding repository routine ps3_repository_find_device_by_id() which can be used to retrieve the device info from the repository.
