2008-11-06powerpc/boot: Allocate more memory for dtbSebastian Siewior
David Gibson suggested that since we are now unconditionally copying the dtb into a malloc()ed buffer, it would be sensible to add a little padding to the buffer at that point, so that further device tree manipulations won't need to reallocate it. This implements that suggestion. Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Paul Mackerras <paulus@samba.org>
2008-11-06powerpc: Hugetlb pgtable cache access cleanupJon Tollefson
Andrew Morton suggested that using a macro that makes an array reference look like a function call makes it harder to understand the code. This therefore removes the huge_pgtable_cache(psize) macro and replaces its uses with pgtable_cache[HUGE_PGTABLE_INDEX(psize)].

2008-11-06powerpc: Eliminate unused do_gtod variablePaul Mackerras
Since we started using the generic timekeeping code, we haven't had a powerpc-specific version of do_gettimeofday, and hence there is now nothing that reads the do_gtod variable in arch/powerpc/kernel/time.c. This therefore removes it and the code that sets it. Signed-off-by: Paul Mackerras <paulus@samba.org>
2008-11-06powerpc: Improve resolution of VDSO clock_gettimePaul Mackerras
Currently the clock_gettime implementation in the VDSO produces a result with microsecond resolution for the cases that are handled without a system call, i.e. CLOCK_REALTIME and CLOCK_MONOTONIC. The nanoseconds field of the result is obtained by computing a microseconds value and multiplying by 1000. This changes the code in the VDSO to do the computation for clock_gettime with nanosecond resolution. That means that the resolution of the result will ultimately depend on the timebase frequency. Because the timestamp in the VDSO datapage (stamp_xsec, the real time corresponding to the timebase count in tb_orig_stamp) is in units of 2^-20 seconds, it doesn't have sufficient resolution for computing a result with nanosecond resolution. Therefore this adds a copy of xtime to the VDSO datapage and updates it in update_gtod() along with the other time-related fields. Signed-off-by: Paul Mackerras <paulus@samba.org>
2008-11-06powerpc: Remove map_/unmap_single() from dma_mapping_opsMark Nelson
Now that all of the remaining dma_mapping_ops have had their map_/unmap_single functions updated to become map/unmap_page functions, there is no need to have the map_/unmap_single function pointers in the dma_mapping_ops. So, this removes them and also removes the code that does the checking for which set of functions to use.

2008-11-06powerpc/pci: Fix various pseries PCI hotplug issuesBenjamin Herrenschmidt
The pseries PCI hotplug code has a number of issues, ranging from incorrect resource setup to crashes, depending on what is added, when, whether it contains a bridge, etc etc.... This fixes a whole bunch of these, while actually simplifying the code a bit, using more generic code in the process and factoring out common code between adding of a PHB, a slot or a device.

2008-11-06powerpc/pci: Make pcibios_allocate_bus_resources more robustBenjamin Herrenschmidt
To properly fix PCI hotplug, it's useful to be able to make the fixup passes on all devices whether they were just hot plugged or already there. However, pcibios_allocate_bus_resources() wouldn't cope well with being called twice for a given bus. This makes it ignore resources that have already been allocated, along with adding a bit of debug output.

To properly fix PCI hotplug, it's useful to be able to make the fixup passes on all devices whether they were just hot plugged or already there. The EEH code however used to not be very friendly with calling eeh_add_device_late() multiple time, and not very rebust in the way it generally tests whether a device is in the expected state vs. the EEH code. This improves it, along with cleaning up a couple of debug printk's. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
2008-11-06powerpc/pci: Split pcibios_fixup_bus() into bus setup and device setupBenjamin Herrenschmidt
Currently, our PCI code uses the pcibios_fixup_bus() callback, which is called by the generic code when probing PCI buses, for two different things. One is to set up things related to the bus itself, such as reading bridge resources for P2P bridges, fixing them up, or setting up the iommu's associated with bridges on some platforms. The other is some setup for each individual device under that bridge, mostly setting up DMA mappings and interrupts. The problem is that this approach doesn't work well with PCI hotplug when an existing bus is re-probed for new children. We fix this problem by splitting pcibios_fixup_bus into two routines: pcibios_setup_bus_self() is now called to setup the bus itself pcibios_setup_bus_devices() is now called to setup devices pcibios_fixup_bus() is then modified to call these two after reading the bridge bases, and the OF based PCI probe is modified to avoid calling into the first one when rescanning an existing bridge.

2008-11-05powerpc/pci: Remove pcibios_do_bus_setup()Benjamin Herrenschmidt
The function pcibios_do_bus_setup() was used by pcibios_fixup_bus() to perform setup that is different between the 32-bit and 64-bit code. This difference no longer exists, thus the function is removed and the setup now done directly from pci-common.c.

2008-11-05powerpc/pci: Use common PHB resource hookupBenjamin Herrenschmidt
The 32-bit and 64-bit powerpc PCI code used to set up the resource pointers of the root bus of a given PHB in completely different places. This unifies this in large part, by making 32-bit use a routine very similar to what 64-bit does when initially scanning the PCI busses. The actual setup of the PHB resources itself is then moved to a common function in pci-common.c. This should cause no functional change on 64-bit. On 32-bit, the effect is that the PHB resources are going to be setup a bit earlier, instead of being setup from pcibios_fixup_bus().

2008-11-05powerpc: Update 64bit memcpy() using CPU_FTR_UNALIGNED_LD_STDMark Nelson
Update memcpy() to add two new feature sections: one for aligning the destination before copying and one for copying using aligned load and store doubles. These new feature sections will only affect Power6 and Cell because the CPU feature bit was only added to these two processors. Power6 gets its best performance in memcpy() when aligning neither the source nor the destination, while Cell gets its best performance when just the destination is aligned. But in order to save on CPU feature bits we can use the previously added CPU_FTR_CP_USE_DCBTZ feature bit to differentiate between Power6 and Cell (because CPU_FTR_CP_USE_DCBTZ was added to Cell but not Power6). The first feature section acts to nop out the branch that takes us to the code that aligns us to an eight byte boundary for the destination. We only want to nop out this branch on Power6. So the ALT_FTR_SECTION_END() for this feature section creates a test mask of the two feature bits ORed together and provides an expected result of just CPU_FTR_UNALIGNED_LD_STD, thus we nop out the branch if we're on a CPU that has CPU_FTR_UNALIGNED_LD_STD set and CPU_FTR_CP_USE_DCBTZ unset. For the second feature section added, if we're on a CPU that has the CPU_FTR_UNALIGNED_LD_STD bit set then we don't want to do the copy with aligned loads and stores (and the appropriate shifting left and right instructions), so we want to nop out the branch to .Lsrc_unaligned. The andi. used for this branch is moved to just above the branch because this allows us to nop out both instructions with just one feature section which gives us better performance and doesn't hurt readability which two separate feature sections did. Moving the andi. to just above the branch doesn't have any noticeable negative effect on the remaining 64bit processors (the ones that didn't have this feature bit added). On Cell this simple modification results in an improvement to measured memcpy() bandwidth of up to 50% in the hot cache case and up to 15% in the cold cache case. On Power6 we get memory bandwidth results that are up to three times faster in the hot cache case and up to 50% faster in the cold cache case. Commit 2a9294369bd020db89bfdf78b84c3615b39a5c84 ("powerpc: Add new CPU feature: CPU_FTR_CP_USE_DCBTZ") was where CPU_FTR_CP_USE_DCBTZ was added. To say that Cell gets its best performance in memcpy() with just the destination aligned is true but only for the reason that the indirect shift and rotate instructions, sld and srd, are microcoded on Cell. This means that either the destination or the source can be aligned, but not both, and seeing as we get better performance with the destination aligned we choose this option. While we're at it make a one line change from cmpldi r1,... to cmpldi cr1,... for consistency. Signed-off-by: Mark Nelson <markn@au1.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

Add a new CPU feature bit, CPU_FTR_UNALIGNED_LD_STD, to be added to the 64bit powerpc chips that can do unaligned load double and store double without any performance hit. This is added to Power6 and Cell and will be used in the next commit to disable the code that gets the destination address aligned on those CPUs where doing that doesn't improve performance.

2008-11-05powerpc/pseries: Fix getting the server number sizeSebastien Dugue
The 'ibm,interrupt-server#-size' properties are not in the cpu nodes, which is where we currently look for them, but rather live under the interrupt source controller nodes (which have "ibm,ppc-xics" in their compatible property). This moves the code that looks for the ibm,interrupt-server#-size properties from xics_update_irq_servers() into xics_init_IRQ(). Also this adds a check for mismatched sizes across the interrupt source controller nodes. Not sure this is necessary as in this case the firmware might be seriously busted. This property only appears on POWER6 boxes and is only used in the set-indicator(gqirm) call, and apparently firmware currently ignores the value we pass. Nevertheless we need to fix it in case future firmware versions use it.

2008-11-05powerpc: Silence software timebase syncBenjamin Herrenschmidt
When no hardware method is provided to sync the timebase registers across the machine, and the platform doesn't sync them for us, then we use a generic software implementation. Currently, the code for that has many printks, and they don't have log levels. Most of the printks are only useful for debugging the code, and since we haven't had any problems with it for years, this turns them into pr_debug.

2008-11-05powerpc: Fix domain numbers in /proc on 64-bitBenjamin Herrenschmidt
The code to properly expose domain numbers in /proc is somewhat bogus on ppc64 as it depends on the "buid" field being non-0, but that field is really pseries specific. This removes that code and makes ppc64 use the same code as 32-bit which effectively decides whether to expose domains based on ppc_pci_flags set by the platform, and sets the default for 64-bit to enable domains and enable compatibility for domain 0 (which strips the domain number for domain 0 to help with X servers).

2008-11-04sata_nv: fix generic, nf2/3 detection regressionTejun Heo
All three flavors of sata_nv's are different in how their hardreset behaves. * generic: Hardreset is not reliable. Link often doesn't come online after hardreset. * nf2/3: A little bit better - link comes online with longer debounce timing. However, nf2/3 can't reliable wait for the first D2H Register FIS, so it can't wait for device readiness or classify the device after hardreset. Follow-up SRST required. * ck804: Hardreset finally works. The core layer change to prefer hardreset and follow up changes exposed the above issues and caused various detection regressions for all three flavors.

2008-11-04sata_promise: add ATA engine reset to reset opsMikael Pettersson
Promise ATA engines need to be reset when errors occur. That's currently done for errors detected by sata_promise itself, but it's not done for errors like timeouts detected outside of the low-level driver. The effect of this omission is that a timeout tends to result in a sequence of failed COMRESETs after which libata EH gives up and disables the port. At that point the port's ATA engine hangs and even reloading the driver will not resume it. To fix this, make sata_promise override ->hardreset on SATA ports with code which calls pdc_reset_port() on the port in question before calling libata's hardreset. PATA ports don't use ->hardreset, so for those we override ->softreset instead. Signed-off-by: Mikael Pettersson <mikpe@it.uu.se> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2008-11-03mv643xx_eth: fix SMI bus access timeoutsLennert Buytenhek
The mv643xx_eth mii bus implementation uses wait_event_timeout() to wait for SMI completion interrupts. If wait_event_timeout() would return zero, mv643xx_eth would conclude that the SMI access timed out, but this is not necessarily true -- wait_event_timeout() can also return zero in the case where the SMI completion interrupt did happen in time but where it took longer than the requested timeout for the process performing the SMI access to be scheduled again. This would lead to occasional SMI access timeouts when the system would be under heavy load. The fix is to ignore the return value of wait_event_timeout(), and to re-check the SMI done bit after wait_event_timeout() returns to determine whether or not the SMI access timed out.
