From 0eb2e6019ae8e76a537bdca07b31e1524a3bba48 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Wed, 1 Nov 2006 15:53:00 +1100 Subject: [POWERPC] pmac_feature_call checks platform This patch makes sure that a caller of pmac_call_feature() won't try to call into ppc_md.feature_call of another platform, which might happen if some powermac drivers are loaded on non-powermac machines.

As a result, the loop searching for this propery, in pci_dma_dev_setup_pSeriesLP(), can run to the end, resulting in a NULL pointer dereference later in the routine. This patch prevents the crash, and prints a warning message. This is theoretically a rare error, as it occurs on what is hopefully just beta levels of firmware.

It also substantially simplifies arch/powerpc/mm/44x_mmu.c and makes a couple of small fixes necessary for the 44x MMU code to build and work properly in arch/powerpc.

This patch fixes a couple of simple build fixes if the option is selected. First, pud_t mustn't be defined in page.h on 32-bit systems, because it conflicts with the version in the generic pud-folding code. Second, pci_32.c is missing a __pgprot() wrapper call. Third, a couple of PS3 files use constants of type pgprot_t when they need the raw values, we add pgprot_val() calls to fix this.

Those asm-ppc files are a fairly nasty tangle of #ifdefs including a bunch of things which shouldn't be necessary any more in arch/powerpc. Cleaning up that mess is going to take a while, but this patch is a first step. It separates the asm-powerpc/pg{alloc,table}.h into 64 bit and 32 bit versions in asm-powerpc, which the basic .h files in asm-powerpc select based on config. We make a few tiny tweaks to the innards of the files along the way, making the outermost ifdefs (double-inclusion protection and __KERNEL__) a little cleaner, and #including asm-generic/pgtable.h from the top-level asm-powerpc/pgtable.h (since both the old 32-bit and 64-bit versions ended with such an #include).

As I'm now getting more familiar with the suspend code I notice a few more things: 1. we previously misunderstood what pm_ops is for, it isn't supposed to be for doing platform dependent suspend/resume stuff that needs to be done for suspend to disk (as we currently try to use it!), it is instead for entering platform dependent suspend states ("standby", "mem"). 2. due to the first point, we never properly save FPU and altivec states when suspending to disk. It probably hasn't hurt yet because the process that writes the "disk" to /sys/power/state uses neither and its context is used. This patch addresses these points as follows: 1. remove all pm_ops from powermac, powermac suspend to ram isn't currently usable via /sys/power/state but is done via the PMU instead. 2. move the code responsible for storing FPU/altivec state into save_processor_state and the set_context() call to restore_processor_state. 3. add a call to kernel_enable_spe() It may look like there is some code removal missing but that is actually because the new suspend.h file overrides the ppc/suspend.h one which was previously used.

First, it ensures that the zlib.h header is linked in before attempting to build gunzip_util.o, as it is, building gunzip_util.o usually works, but not always depending on make order. Second, it makes the final images which are built using a dts dependent on that dts, so the image will be correctly rebuilt if the dts changes. This in turn requires fixing the definition of the dts variable. CONFIG_DEVICE_TREE from Kconfig will have quotes around it, which don't matter when passing the variable to a shell, but which need to be removed when incorporating it into a filename for make's use.

SDRAM is put into self-refresh with help of SRAM code (alternatives would be code in FLASH, I-cache). Interrupt code must also not be in SDRAM, so put it in I-cache. MPC52xx core is static, so contents will remain intact even with clocks turned off.

If this is not true, we can end up with I/O port numbers in the resources for PCI devices which will cause an oops if a driver tries to access them via inb/outb etc., because there is no mapping for the corresponding addresses. Normally the I/O window starts at 0, but there are some situations on partitioned machines with a hypervisor where the window may not start at 0. This fixes the problem by allocating space for the range from 0 to the end of the I/O window. That is, hose->io_base_virt contains the virtual address for I/O port 0 on the PCI bus, and thus the assumption that hose->io_base_virt - pci_io_base is the offset between the "global" I/O port numbers (those in the PCI device resources) and the I/O port numbers on the PCI bus is maintained. For PCI host bridges that are present at boot, we only map the portion of that range that correspond to the bridge's I/O window. For bridges added after boot we ioremap the range from 0 to the end of the I/O window, for now; in fact hot-added bridges should be using reserve_phb_iospace() and __ioremap_explicit (so they get sensible global port numbers), but we don't have the infrastructure yet to do that (basically a free_phb_iospace() routine plus appropriate locking). Interestingly, this makes the two arms of the if statement in get_bus_io_range do almost exactly the same thing; that function could now be simplified in a further patch.

For now we assumes that if the required RTAS tokens for MSI are present, then we want to use the RTAS MSI routines. When RTAS is managing MSIs for us, it will/may enable MSI on devices that support it by default. This is contrary to the Linux model where a device is in LSI mode until the driver requests MSIs. To remedy this we add a pci_irq_fixup call, which disables MSI if they've been assigned by firmware and the device also supports LSI. Devices that don't support LSI at all will be left as is, drivers are still expected to call pci_enable_msi() before using the device. At the moment there is no pci_irq_fixup on pSeries, so we can just set it unconditionally. If other platforms use the RTAS MSI backend they'll need to check that still holds.

Based on code from Segher, heavily hacked by me. This only deals with MSI on U3/U4 MPICs, aka. CPC 9x5. If we find a U3/U4 then we enable this backend, ie. take over the ppc_md MSI hooks. We might need more elaborate logic in future to decide which backend is enabled. We need our own irq_chip so that we can do MSI masking/unmasking on the device itself. We also need to mask explicitly on shutdown to make sure we don't get bitten by lazy-disable semantics.

It is populated with a single misc_44x.S file, into which is moved the 44x specific reset code from head_44x.S (on the grounds that we should really stop clogging up the head_* files with random asm helper routines). At the same time, we disable the (empty save Kconfig and Makefile) arch/powerpc/platforms/4xx directory from the arch/powerpc/platforms Makefile. Contrary to the comment in arch/powerpc/platforms/4xx/Makefile, attempting to build such an empty Makefile will fail, thus breaking compile for the 44x platforms we're about to add. It can go back in once we start porting some of the 40x platforms (and thus it becomes non-empty).

This includes both code in arch/powerpc/platforms/44x for board initialization, and zImage wrapper code to correctly tweak the flattened device tree based on information from the firmware. The zImage supports both IBM OpenBIOS (aka "treeboot") and old versions of uboot which don't support a flattened device tree.

adds support for early serial debugging via the built in port on IBM/AMCC PowerPC 44x CPUs. It uses a bolted TLB entry in address space 1 for the UART's mapping, allowing robust debugging both before and after the initialization of the MMU.

It finds all nodes in the device tree with device_type=="rom" and instantiates of_platform devices for them. This is fundamentally incompatible with the normal and correct way of probing for of_platform_bus_probe(). Platforms which relied on powerpc_flash_init()s behaviour (none are in-tree) will have to update their platform probing code to correctly probe busses containing flash devices.
