由 Alexandr Smirnov 提交于
The KSI8560 is a single compact, mid-, or full-size Advanced Mezzanine Card (AdvancedMC™) based on the Freescale™ Semiconductor MPC8560 PowerQUICC III™ microprocessor. This product will serve in data and signaling applications such as signaling gateways (SGW) and softswitch signaling interface cards. The board has altera maxii CPLD, that is used to obtain and manage board configuration. Also there are two SCC UART serial consoles and FCC ethernet, that is routed to the front panel, while other ethernet controlers (TSEC's) are routed to the backplane.

This adds a kernel command line option "phyp_dump", which takes a 0/1 value for disabling/ enabling phyp_dump at boot time. Kdump can use this on cmdline (phyp_dump=0) to disable phyp-dump during boot when enabling itself. This will ensure only one dumping mechanism is active at any given time.

Check to see if there actually is data from a previously crashed kernel waiting. If so, allow user-space tools to grab the data (by reading /proc/kcore). When user-space finishes dumping a section, it must release that memory by writing to sysfs. For example, echo "0x40000000 0x10000000" > /sys/kernel/release_region will release 256MB starting at the 1GB. The released memory becomes free for general use.

The hypervisor can look at the value in the wait_state_cycles field of the VPA for an estimate of how busy dedicated processors are. Currently, as the kernel never touches this field, we appear to be 100% busy. This records the duration the kernel is in powersave and passes that to the HV to provide a reasonable indication of utilisation.

Prevailing practice for define_machine() in powerpc is to use the platform name when the platform has only one define_machine() statement, but maple uses "maple_md". This caused me some head-scratching when writing some new code that uses machine_is(maple). Use "maple" instead of "maple_md". There should not be any behavioral change -- fixup_maple_ide() calls machine_is(maple) but the body of the function is ifdef'd out.

The "bestcomm-core" driver defines its of_match table as follows static struct of_device_id mpc52xx_bcom_of_match[] = { { .type = "dma-controller", .compatible = "fsl,mpc5200-bestcomm", }, { .type = "dma-controller", .compatible = "mpc5200-bestcomm", }, {}, }; so while registering the driver, the driver's probe function won't be called, because the device tree node doesn't have a device_type property. Thus the driver's bcom_engine structure won't be allocated. Referencing this structure later causes observed Oops. Checking bcom_eng pointer for NULL before referencing data pointed by it prevents oopsing, but fec driver still doesn't work (because of the lost bestcomm match and resulted task allocation failure). Actually the compatible property exists and should match and so the fec driver should work. This removes .type = "dma-controller" from the bestcomm driver's mpc52xx_bcom_of_match table to solve the problem.

On pSeries, the hypervisor doesn't let us map in the eHEA ethernet adapter using 64k pages, and thus the ehea driver will fail if 64k pages are configured. This works around the problem by always using 4k pages for ioremap on pSeries (but not on other platforms). A better fix would be to check whether the partition could ever have an eHEA adapter, and only force 4k pages if it could, but this will do for 2.6.25. This is based on an earlier patch by Tony Breeds. Signed-off-by: NPaul Mackerras <paulus@samba.org>

The cell IOMMU code to parse the dma-ranges properties, used for the fixed mapping, was broken in two ways for some devices. Firstly it didn't cope with empty dma-ranges properties. An empty property implies no translation so can be safely skipped. The code also wrongly assumed it would be looking at PCI devices, and hard coded the number of address and size cells.

Since the PMU is an NMI now, it can come at any time we are only soft disabled. We must hard disable around the two places we allow the kernel stack SLB and r1 to go out of sync.

The PTRACE_SETREGS request was only recently added on powerpc, and gdb does not use it. So it slipped through without getting all the testing it should have had. The user_regset changes had a simple bug in storing to all of the 32-bit general registers block on 64-bit kernels. This bug only comes up with PTRACE_SETREGS, not PPC_PTRACE_SETREGS. It causes a BUG_ON to hit, so this fix needs to go in ASAP. Signed-off-by: NRoland McGrath <roland@redhat.com> Signed-off-by: NPaul Mackerras <paulus@samba.org>

My recent hack to allocate the hash table under 1GB on cell was poorly tested, *cough*. It turns out on blades with large amounts of memory we fail to allocate the hash table at all. This is because RTAS has been instantiated just below 768MB, and 0-x MB are used by the kernel, leaving no areas that are both large enough and also naturally-aligned. For the cell IOMMU hack the page tables must be under 2GB, so use that as the limit instead. This has been tested on real hardware and boots happily.

A bogus test for unassigned resources that came from our 32-bit PCI code ended up being "merged" by my previous patch series, breaking some 64-bit setups where devices have legal resources ending at 0xffffffff. This fixes it by completely changing the test. We now test for res->start == 0, as the generic code expects, and we also only do so on platforms that don't have the PPC_PCI_PROBE_ONLY flag set, as there are cases of pSeries and iSeries where it could be a valid value and those can't reassign devices.

The pattern substitution rules were failing when used with zImage-dtb targets. If zImage-dtb.initrd was selected, the pattern substitution would generate "zImage.initrd-dtb" instead of "zImage-dtb.initrd" which caused the build to fail.
