Dear all,
I have a problem in MPC5121 sleep mode. As you know MPC5121 use e300c4
core. When I make the e300c4 core into sleep mode, it will return to
full power mode when the“decrementer interrupt” occurred.
But in the e300 core reference manual said that the “decrementer
interrupt”have no
Hi all,
I am a newbie to the powerpc linux kernel, but I have worked
on some drivers in arm architecture. I am finding powerpc architecture to be
fully different than that.
I am working on Freescale MPC5121e with the BSP MPC512xADS_20090603-ltib.iso
running in it on the ADS512101
Hi Prodyut,
Yes, I am using the 440EPx (same as the sequoia board).
Our ideDriver is DMA'ing blocks of 192-byte data over the PCI bus (using
the Sil0680A PCI-IDE bridge). Most of the DMA's (depending on timing)
end up being partially corrupted when we try to parse the data in the
virtual page.

The following commit introduced a compile error since it removed
the implementation of smp_85xx_basic_setup:

We have found that using flush_dcache_range() after each DMA solves
the
problem. Ideally, we'd like to be able to allocate the virtual page in
cache inhibited memory to avoid the performance loss from all the
flush
calls. To do this, we'd have to change our TLB sizes and reserve a TLB

Why explicitely setting those to NULL ?

Powerpc 44x uses 36 bit real address while the real address defined
in MPT Fusion driver is of type 32 bit. This causes ioremap to fail and driver
fails to initialize. This fix changes the data types representing the real
address from unsigned long 32-bit
Also remove a duplicate setting of it in the context switch path
on BookE.

One I2C driver has been included in 0603 bsp, you can refer to it.
It has no specific driver for GPIO, but you can find some initializing
code for GPIO in arch/powerpc/platforms/512x/mpc5125_ads.c. and
mpc512x_pm_test.c.

Then your flush should have no effect since pci_alloc_consistent will
return I=1 mapped memory, unless you don't have
CONFIG_NOT_COHERENT_CACHE for some reason.

powerpc: Properly start decrementer on
Currently, ordinary pages use one pagetable layout, and each different
hugepage size uses a slightly different variant layout. A number of
places which need to walk the pagetable must first check the slice map
to see what the pagetable layout then handle the various different
forms. New
Currently, hpte_need_flush() only correctly flushes the given address
for normal pages. Callers for hugepages are required to mask the
address themselves.
But hpte_need_flush() already looks up the page sizes for its own
reasons, so this is a rather silly imposition on the callers. This
