2008-12-03powerpc/qe: Move cmxgcr_lock definition from the ucc.c into the qe.cAnton Vorontsov2-3/+4
With this patch we can compile the qe_lib/usb.c without the UCC support (that is, without UCC_GETH and/or SERIAL_QE). Fixes following link error (CONFIG_SMP should be =y to trigger this): arch/powerpc/sysdev/built-in.o: In function `qe_usb_clock_set': (.text+0x3cae): undefined reference to `cmxgcr_lock' make: *** [.tmp_vmlinux1] Error 1 While at it, also add missing spinlock.h includes.

2008-12-02powerpc: Use physical cpu id when setting the processor affinityKumar Gala1-1/+1
In the CONFIG_SMP case the irq_choose_cpu() code was returning back a logical cpu id not the physical id. We were writing that directly into the HW register. We need to be calling get_hard_smp_processor_id() so irq_choose_cpu() always returns a physical cpu id. Signed-off-by: Kumar Gala <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>
2008-12-01powerpc/mpic: Don't reset affinity for secondary MPIC on bootArnd Bergmann1-2/+7
Kexec/kdump currently fails on the IBM QS2x blades when the kexec happens on a CPU other than the initial boot CPU. It turns out that this is the result of mpic_init trying to set affinity of each interrupt vector to the current boot CPU. As far as I can tell, the same problem is likely to exist on any secondary MPIC, because they have to deliver interrupts to the first output all the time. There are two potential solutions for this: either not set up affinity at all for secondary MPICs, or assume that a single CPU output is connected to the upstream interrupt controller and hardcode affinity to that per architecture. This patch implements the second approach, defaulting to the first output. Currently, all known secondary MPICs are routed to their upstream port using the first destination, so we hardcode that.

2008-11-19powerpc/mpic: Use new smp_request_message_ipiMilton Miller1-28/+4
MPIC has 4 ipis, so it can use the new smp_request_message_ipi to reduce pathlength when receiving an ipi. This has the side effect of using the common ipi names, and also continuing to try request the remaining messages when one fails.

2008-10-31powerpc/mpic: Fix regression caused by change of default IRQ affinityKumar Gala1-4/+55
The Freescale implementation of MPIC only allows a single CPU destination for non-IPI interrupts. We add a flag to the mpic_init to distinquish these variants of MPIC. We pull in the irq_choose_cpu from sparc64 to select a single CPU as the destination of the interrupt. This is to deal with the fact that the default smp affinity was changed by commit 18404756765c713a0be4eb1082920c04822ce588 ("genirq: Expose default irq affinity mask (take 3)") to be all CPUs.

2008-10-31gianfar: Fix race in TBI/SerDes configurationTrent Piepho1-0/+26
The init_phy() function attaches to the PHY, then configures the SerDes<->TBI link (in SGMII mode). The TBI is on the MDIO bus with the PHY (sort of) and is accessed via the gianfar's MDIO registers, using the functions gfar_local_mdio_read/write(), which don't do any locking. The previously attached PHY will start a work-queue on a timer, and probably an irq handler as well, which will talk to the PHY and thus use the MDIO bus. This uses phy_read/write(), which have locking, but not against the gfar_local_mdio versions. The result is that PHY code will try to use the MDIO bus at the same time as the SerDes setup code, corrupting the transfers. Setting up the SerDes before attaching to the PHY will insure that there is no race between the SerDes code and *our* PHY, but doesn't fix everything. Typically the PHYs for all gianfar devices are on the same MDIO bus, which is associated with the first gianfar device. This means that the first gianfar's SerDes code could corrupt the MDIO transfers for a different gianfar's PHY. The lock used by phy_read/write() is contained in the mii_bus structure, which is pointed to by the PHY. This is difficult to access from the gianfar drivers, as there is no link between a gianfar device and the mii_bus which shares the same MDIO registers. As far as the device layer and drivers are concerned they are two unrelated devices (which happen to share registers). Generally all gianfar devices' PHYs will be on the bus associated with the first gianfar. But this might not be the case, so simply locking the gianfar's PHY's mii bus might not lock the mii bus that the SerDes setup code is going to use. We solve this by having the code that creates the gianfar platform device look in the device tree for an mdio device that shares the gianfar's registers. If one is found the ID of its platform device is saved in the gianfar's platform data. A new function in the gianfar mii code, gfar_get_miibus(), can use the bus ID to search through the platform devices for a gianfar_mdio device with the right ID. The platform device's driver data is the mii_bus structure, which the SerDes setup code can use to lock the current bus.

2008-10-13powerpc: fix fsl_upm nand driver modular buildAnton Vorontsov1-4/+49
The fsl_upm nand driver fails to build because fsl_lbc_lock isn't exported, the lock is needed by the inlined fsl_upm_run_pattern() function: ERROR: "fsl_lbc_lock" [drivers/mtd/nand/fsl_upm.ko] undefined! Dave Jones purposed to export the lock, but it is better to just uninline the fsl_upm_run_pattern(). When uninlined we also no longer need the exported fsl_lbc_regs, and both fsl_lbc_lock and fsl_lbc_regs could be marked static.

Currently, there are two different fields in the mv643xx_eth_platform_data struct that together describe the PHY address -- one field (phy_addr) has the address of the PHY, but if that address is zero, a second field (force_phy_addr) needs to be set to distinguish the actual address zero from a zero due to not having filled in the PHY address explicitly (which should mean 'use the default PHY address').

There are now two almost identical implementations of an MSI bitmap allocator, one in mpic_msi.c and the other in fsl_msi.c. Merge them together and put the result in msi_bitmap.c. Some of the MPIC bits will remain to provide a nicer interface for the MPIC users. In the process we fix two buglets. The first is that the allocation routines, now msi_bitmap_alloc_hwirqs(), returned an unsigned result, even though they use -1 to indicate allocation failure. Although all the callers were checking correctly, it is much better for the routine to just return an int. At least until someone wants > ~2 billion MSIs. The second buglet is that the device tree reservation logic only allowed power-of-two reservations. AFAICT that didn't effect any existing code but it's nicer if we can reserve arbitrary irqs from MSI use. We also add some selftests, which exposed the two buglets and now test for them, as well as some basic sanity tests. The tests are only built when CONFIG_DEBUG_KERNEL=y.

To support Cooperative Memory Overcommitment (CMO), we need to check for failure from some of the tce hcalls. These changes for the pseries platform affect the powerpc architecture; patches for the other affected platforms are included in this patch. pSeries platform IOMMU code changes: * platform TCE functions must handle H_NOT_ENOUGH_RESOURCES errors and return an error. Architecture IOMMU code changes: * Calls to ppc_md.tce_build need to check return values and return DMA_MAPPING_ERROR for transient errors. Architecture changes: * struct machdep_calls for tce_build*_pSeriesLP functions need to change to indicate failure. * all other platforms will need updates to iommu functions to match the new calling semantics; they will return 0 on success. The other platforms default configs have been built, but no further testing was performed.
