2018-03-13powerpc/powernv/mce: Don't silently restart the machineBalbir Singh1-1/+4
On MCE the current code will restart the machine with ppc_md.restart(). This case was extremely unlikely since prior to that a skiboot call is made and that resulted in a checkstop for analysis. With newer skiboots, on P9 we don't checkstop the box by default, instead we return back to the kernel to extract useful information at the time of the MCE. While we still get this information, this patch converts the restart to a panic(), so that if configured a dump can be taken and we can track and probably debug the potential issue causing the MCE.

2018-03-13powerpc/powernv: Enable tunneled operationsPhilippe Bergheaud6-9/+148
P9 supports PCI tunneled operations (atomics and as_notify). This patch adds support for tunneled operations on powernv, with a new API, to be called by device drivers: pnv_pci_enable_tunnel() Enable tunnel operations, tell driver the 16-bit ASN indication used by kernel. pnv_pci_disable_tunnel() Disable tunnel operations. pnv_pci_set_tunnel_bar() Tell kernel the Tunnel BAR Response address used by driver. This function uses two new OPAL calls, as the PBCQ Tunnel BAR register is configured by skiboot. pnv_pci_get_as_notify_info() Return the ASN info of the thread to be woken up.

2018-03-13powerpc/powernv/npu: Fix deadlock in mmio_invalidate()Alistair Popple1-87/+140
When sending TLB invalidates to the NPU we need to send extra flushes due to a hardware issue. The original implementation would lock the all the ATSD MMIO registers sequentially before unlocking and relocking each of them sequentially to do the extra flush. This introduced a deadlock as it is possible for one thread to hold one ATSD register whilst waiting for another register to be freed while the other thread is holding that register waiting for the one in the first thread to be freed. For example if there are two threads and two ATSD registers: Thread A Thread B ---------------------- Acquire 1 Acquire 2 Release 1 Acquire 1 Wait 1 Wait 2 Both threads will be stuck waiting to acquire a register resulting in an RCU stall warning or soft lockup. This patch solves the deadlock by refactoring the code to ensure registers are not released between flushes and to ensure all registers are either acquired or released together and in order.

2018-03-13powerpc/xmon: Clear all breakpoints when xmon is disabled via debugfsVaibhav Jain1-0/+24
Presently when xmon is disabled by debugfs any existing instruction/data-access breakpoints set are not disabled. This may lead to kernel oops when those breakpoints are hit as the necessary debugger hooks aren't installed. Hence this patch introduces a new function named clear_all_bpt() which is called when xmon is disabled via debugfs. The function will unpatch/clear all the trap and ciabr/dab based breakpoints.

2018-03-13powerpc/xmon: Setup debugger hooks when first break-point is setVaibhav Jain1-1/+16
Presently sysrq key for xmon('x') is registered during kernel init irrespective of the value of kernel param 'xmon'. Thus xmon is enabled even if 'xmon=off' is passed on the kernel command line. However this doesn't enable the kernel debugger hooks needed for instruction or data breakpoints. Thus when a break-point is hit with xmon=off a kernel oops of the form below is reported: Oops: Exception in kernel mode, sig: 5 [#1] < snip > Trace/breakpoint trap To fix this the patch checks and enables debugger hooks when an instruction or data break-point is set via xmon console.

2018-03-12ACPI, x86/boot: Introduce the ->reduced_hw_early_init() ACPI callbackAndy Shevchenko3-1/+5
Some ACPI hardware reduced platforms need to initialize certain devices defined by the ACPI hardware specification even though in principle those devices should not be present in an ACPI hardware reduced platform. To allow that to happen, make it possible to override the generic x86_init callbacks and provide a custom legacy_pic value, add a new ->reduced_hw_early_init() callback to struct x86_init_acpi and make acpi_reduced_hw_init() use it.
