* [POWERPC] Start arch/powerpc/boot code reorganizationMark A. Greer2006-09-209-178/+441
| | | | | | | | | | | | | | | This abstracts the operations used in the bootwrapper, and defines the operations needed for the bootwrapper to run on an OF platform. The operations have been divided up into platform ops (platform_ops), firmware ops (fw_ops), device tree ops (dt_ops), and console ops (console_ops). The proper operations will be hooked up at runtime to provide the functionality that you need. Signed-off-by: Mark A. Greer <mgreer@mvista.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
* [POWERPC] Define of_read_ulong helperPaul Mackerras2006-09-203-25/+11
| | | | | | | | | | There are various places where we want to extract an unsigned long value from a device-tree property that can be 1 or 2 cells in length. This replaces some open-coded calculations, and one place where we assumed without checking that properties were the length we wanted, with a little of_read_ulong() helper.

| | * [POWERPC] Fix G5 DART (IOMMU) race causing occasional data corruptionBenjamin Herrenschmidt2006-09-131-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It seems that the occasional data corruption observed with the tg3 driver wasn't due to missing barriers after all, but rather seems to be due to the DART (= IOMMU) in the U4 northbridge reading stale IOMMU table entries from memory due to a race. This fixes it by making the CPU read the entry back from memory before using it. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>

To preserve ordering between writeX and readX, and to preserve ordering between preceding stores and the readX, the readX family of functions have had an sync added before the load. Although writeX followed by spin_unlock is not officially guaranteed to keep the writeX inside the spin-locked region unless an mmiowb() is used, there are currently drivers that depend on the previous behaviour on powerpc, which was that the mmiowb wasn't actually required. Therefore we have a per-cpu flag that is set by writeX, cleared by __raw_spin_lock and mmiowb, and tested by __raw_spin_unlock. If it is set, __raw_spin_unlock does a sync and clears it. This changes both 32-bit and 64-bit readX/writeX. 32-bit already has a sync in __raw_spin_unlock (since lwsync doesn't exist on 32-bit), and thus doesn't need the per-cpu flag. Tested on G5 (PPC970) and POWER5. Signed-off-by: Paul Mackerras <paulus@samba.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | As part of the new irq code pseries_kexec_cpu_down() was split into a xics and mpic version. The vpa unregister logic is now only done in the xics routine, and although that's ok in practice (we don't have SPLPAR machines with mpic), I'd rather have the two concepts stay separate. So move the vpa unregister into pseries_kexec_cpu_down(), which gets called by both the xics and mpic routines. This also gives us an obvious place to put any new kexec-down logic needed in future.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Eran Ben-Avi <eranpublic@yahoo.com> pointed out that the arch/ppc version of smp_generic_take_timebase disables interrupts on entry but exits without restoring them. However, both it and the arch/powerpc version have another problem, which is that they use local_irq_disable/enable rather than local_irq_save/restore, and they are called with interrupts disabled. This fixes both problems; it changes a return to a break in the arch/ppc version, and changes both versions to use local_irq_save/restore. Signed-off-by: Paul Mackerras <paulus@samba.org>
| | * [POWERPC] Fix problem with time not advancing on 32-bit platformsPaul Mackerras2006-08-301-17/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a problem introduced in 5db9fa9593e2ff69f2b95f9d59229dc4faaa564d. The last_jiffy per-cpu variable is only 32 bits on 32-bit machines, but it was being compared with a 64-bit quantity (tb_next_jiffy), which resulted in time not advancing. This fixes it by changing last_jiffy to be 64 bits on all platforms. With this, we no longer need tb_last_stamp as a 32-bit version of tb_last_jiffy, so this gets rid of tb_last_stamp and we just use tb_last_jiffy instead. This also fixes a bug when the boot cpu is not online, because using tb_last_stamp could have caused the wrong timebase origin value to be used when calculating the time of day.

This enables the mpic code to deal with mpic controllers with different register layouts and hardware behaviours. This introduces CONFIG_MPIC_WEIRD. For boards with non standard mpic controllers, select CONFIG_MPIC_WEIRD and add its hardware information in the mpic_infos[] array. TSI108/109 PIC takes the first index of weird hardware information table. :) The table can be extended. The Tsi108/109 PIC looks like standard OpenPIC but, in fact, is different in register mapping and behavior. The patch does not affect the behavior of standard mpic. If CONFIG_MPIC_WEIRD is not defined, the code is essentially identical to the current code. [benh@kernel.crashing.org: This patch is a slightly cleaned up version of Zang Roy's support for the TSI108 MPIC variant. It also fixes up MPC7448_hpc2 to use the new version of the type macros and changes the way MPIC is selected in Kconfig to better match what is done for other system devices. ] Signed-off-by: Roy Zang <tie-fei.zang@freescale.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>

This makes us use a 64-bit quantity on all platforms, which ends up simplifying the code since we can now get rid of the tb_last_stamp variable (which actually fixes another bug that Ben H and I noticed while going carefully through the code). This works fine on my G4 tibook. Let me know how it goes on your machines.
