In order to enable the DIU video controller on the P1022DS, the FPGA needs to be switched to "indirect mode", where the localbus is disabled and the FPGA is accessed via writes to localbus chip select signals CS0 and CS1. To obtain the address of CS0 and CS1, the platform driver uses an "indirect pixis mode" device tree node. This node assumes that the localbus 'ranges' property is sorted in chip-select order. That is, reg value 0 maps to CS0, reg value 1 maps to CS1, etc. This is how the 'ranges' property is supposed to be arranged. Unfortunately, the 'ranges' property is often mis-arranged, and not just on the P1022DS. Linux normally does not care, since it does not program the localbus. But the indirect-mode code on the P1022DS does care. The "proper" fix is to have U-Boot fix the 'ranges' property, but this would be too cumbersome. The names and 'reg' properties of all the localbus devices would also need to be updated, and determining which localbus device maps to which chip select is board-specific. Instead, we determine the CS0/CS1 base addresses the same way that U-boot does -- by reading the BRx registers directly and mapping them to physical addresses. This code is simpler and more reliable, and it does not require a U-boot or device tree change. Since the indirect pixis device tree node is no longer needed, the node is deleted from the DTS.

This reference board dates back to 2004, and is largely a legacy EOL product. The MPC8560 is a pre e500v2 CPU. The SBC8548 is a more modern, better e500v2 target for people to use as a reference board with today's kernels, should they require one. Removing support for it will also allow us to remove some sbc8560 specific quirk handling in 8250 UART code, and some MTD mapping support.

The p1024rdb has the similar feature as the p1020rdb. Therefore, p1024rdb use the same platform file as the p1/p2 rdb board. Overview of P2020RDB platform - DDR3 1G - NOR flash 16M - 3 Ethernet interfaces - NAND Flash 32M - SPI EEPROM 16M - SD/MMC - 2 USB ports - 4 TDM ports Signed-off-by:

Add EEPROM to the P1010RDB device tree. The 24c01 acts as a memory SPD so it shouldn't be overwritten without care. The 24c256 is a general purpose memory. Signed-off-by:

This reverts commit 0c00f656. The initial commit was my fault. There are two boards out there: P2020RDB and P2020RDB-PC. I wasn't aware of that and assumed that I have a RDB board in front of me while I the RDB-PC. This patch makes it work for the RDB-PC variant and breaks it for the RDB. Now there is a device tree file available for the RDB-PC which was not there earlier. So with this revert, everything gets back to normal :) Signed-off-by:

Add the ability to inject IOMMU faults. We enable this per device via a fail_iommu sysfs property, similar to fault injection on other subsystems. An example: ... 0003:01:00.1 Ethernet controller: Emulex Corporation OneConnect 10Gb NIC (be3) (rev 02) To inject one error to this device: echo 1 > /sys/bus/pci/devices/0003:01:00.1/fail_iommu echo 1 > /sys/kernel/debug/fail_iommu/probability echo 1 > /sys/kernel/debug/fail_iommu/times As feared, the first failure injected on the be3 results in an unrecoverable error, taking down both functions of the card permanently: be2net 0003:01:00.1: Unrecoverable error in the card Signed-off-by:

Similar to PCI, separate the bus probe from device probe. This allows us to attach bus notifiers for DMA debug and IOMMU fault injection before devices have been probed. Signed-off-by:

During boot we see a number of these warnings: vio 30000000: Warning: IOMMU dma not supported: mask 0xffffffffffffffff, table unavailable The reason for this is that we set IOMMU properties for all VIO devices even if they are not DMA capable. Only set DMA ops, table and mask for devices with a DMA window. Signed-off-by:

We use SIAR or regs->nip for the instruction pointer depending on the PMU configuration, but we always use regs->nip in the callchain. Use perf_instruction_pointer so the backtrace is consistent. Signed-off-by:
-
Anton Blanchard authored
At the moment we always use the SIAR if the PMU supports continuous sampling. Unfortunately the SIAR and the PMU exception are not synchronised for non marked events so we can end up with callchains that dont make sense. The following patch checks the HV and PR bits for samples coming from userspace and always uses pt_regs for them. Userspace will never have interrupts off so there is no real advantage to using the SIAR for non marked events in userspace. I had experimented with a patch that did a similar thing for kernel samples but we lost a significant amount of information. I was unable to profile any of our early exception code for example.

Anton Blanchard authored
The logic to choose whether to use the SIAR or get the information out of pt_regs is going to get more complicated, so do it once in perf_read_regs. We overload regs->result which is gross but we are already doing it with regs->dsisr. Signed-off-by:

We want to access the MMCRA_SIHV and MMCRA_SIPR bits elsewhere so create mmcra_sihv and mmcra_sipr which hide the differences between the old and new layout of the bits. Signed-off-by:

Now have ___PPC_RA/B/S/T we can use it in some places. These are places where we can't use the existing defines which will soon enforce R0-R31 usage. The macros being changed here are being used in inline asm, which can't convert to enforce the R0-R31 usage. bpf_jit uses a mix of both generated and non-generated with the same code, so just convert all these to use the ___PPC_R versions which won't enforce R usage later.
