2013-05-14powerpc/perf: Fix setting of "to" addresses for BHRBMichael Neuling1-1/+30
Currently we only set the "to" address in the branch stack when the CPU explicitly gives us a value. Unfortunately it only does this for XL form branches (eg blr, bctr, bctar) and not I and B form branches (eg b, bc). Fortunately if we read the instruction from memory we can extract the offset of a branch and calculate the target address. This adds a function power_pmu_bhrb_to() to calculate the target/to address of the corresponding I and B form branches. It handles branches in both user and kernel spaces. It also plumbs this into the perf brhb reading code. Signed-off-by: Michael Neuling <[email protected]> Signed-off-by: Benjamin Herrenschmidt <[email protected]>
2013-05-14powerpc/pmu: Fix order of interpreting BHRB target entriesMichael Neuling1-43/+46
The current Branch History Rolling Buffer (BHRB) code misinterprets the order of entries in the hardware buffer. It assumes that a branch target address will be read _after_ its corresponding branch. In reality the branch target comes before (lower mfbhrb entry) it's corresponding branch. This is a rewrite of the code to take this into account.

This is the exception hooks for context tracking subsystem, including data access, program check, single step, instruction breakpoint, machine check, alignment, fp unavailable, altivec assist, unknown exception, whose handlers might use RCU.

2013-05-14powerpc/booke64: Fix kernel hangs at kernel_dbg_excScott Wood2-4/+11
MSR_DE is not cleared on entry to the kernel, and we don't clear it explicitly outside of debug code. If we have MSR_DE set in prime_debug_regs(), and the new thread has events enabled in DBCR0 (e.g. ICMP is set in thread->dbsr0, even though it was cleared in the real DBCR0 when the thread got scheduled out), we'll end up taking a debug exception in the kernel when DBCR0 is loaded. DSRR0 will not point to an exception vector, and the kernel ends up hanging at kernel_dbg_exc. Fix this by always clearing MSR_DE when we load new debug state. Another observed source of kernel_dbg_exc hangs is with the branch taken event. If this event is active, but we take a non-debug trap (e.g. a TLB miss or an asynchronous interrupt) before the next branch. We end up taking a branch-taken debug exception on the initial branch instruction of the exception vector, but because the debug exception is DBSR_BT rather than DBSR_IC we branch to kernel_dbg_exc before even checking the DSRR0 address. Fix this by checking for DBSR_BT as well as DBSR_IC, which is what 32-bit does and what the comments suggest was intended in the 64-bit code as well.

We are getting build errors with CONFIG_PROC_FS=n: arch/powerpc/kernel/rtas_flash.c In function 'rtas_flash_init': 745:33: error: unused variable 'f' [-Werror=unused-variable] But rtas_flash.c should not be built when CONFIG_PROC_FS=n, beacause all it does is provide a /proc interface to the RTAS flash routines.

2013-05-14powerpc: Bring all threads online prior to migration/hibernationRobert Jennings3-0/+137
This patch brings online all threads which are present but not online prior to migration/hibernation. After migration/hibernation those threads are taken back offline. During migration/hibernation all online CPUs must call H_JOIN, this is required by the hypervisor. Without this patch, threads that are offline (H_CEDE'd) will not be woken to make the H_JOIN call and the OS will be deadlocked (all threads either JOIN'd or CEDE'd).

2013-05-14powerpc/rtas_flash: Fix validate_flash buffer overflow issueVasant Hegde1-4/+6
ibm,validate-flash-image RTAS call output buffer contains 150 - 200 bytes of data on latest system. Presently we have output buffer size as 64 bytes and we use sprintf to copy data from RTAS buffer to local buffer. This causes kernel oops (see below call trace). This patch increases local buffer size to 256 and also uses snprintf instead of sprintf to copy data from RTAS buffer.

2013-05-14powerpc/kexec: Fix kexec when using VMX optimised memcpyAnton Blanchard1-0/+4
commit b3f271e86e5a (powerpc: POWER7 optimised memcpy using VMX and enhanced prefetch) uses VMX when it is safe to do so (ie not in interrupt). It also looks at the task struct to decide if we have to save the current tasks' VMX state. kexec calls memcpy() at a point where the task struct may have been overwritten by the new kexec segments. If it has been overwritten then when memcpy -> enable_altivec looks up current->thread.regs->msr we get a cryptic oops or lockup. I also notice we aren't initialising thread_info->cpu, which means smp_processor_id is broken. Fix that too.

2013-05-13qlge: fix dma map leak when the last chunk is not allocatedThadeu Lima de Souza Cascardo1-0/+7
qlge allocates chunks from a page that it maps and unmaps that page when the last chunk is released. When the driver is unloaded or the card is removed, all chunks are released and the page is unmapped for the last chunk. However, when the last chunk of a page is not allocated and the device is removed, that page is not unmapped. In fact, its last reference is not put and there's also a page leak. This bug prevents a device from being properly hotplugged. When the DMA API debug option is enabled, the following messages show the pending DMA allocation after we remove the driver. This patch fixes the bug by unmapping and putting the page from the ring if its last chunk has not been allocated. pci 0005:98:00.0: DMA-API: device driver has pending DMA allocations while released from device [count=1] One of leaked entries details: [device address=0x0000000060a80000] [size=65536 bytes] [mapped with DMA_FROM_DEVICE] [mapped as page] ------------[ cut here ]------------ WARNING: at lib/dma-debug.c:746 Modules linked in: qlge(-) rpadlpar_io rpaphp pci_hotplug fuse [last unloaded: qlge] NIP: c0000000003fc3ec LR: c0000000003fc3e8 CTR: c00000000054de60 REGS: c0000003ee9c74e0 TRAP: 0700 Tainted: G O (3.7.2) MSR: 8000000000029032 <SF,EE,ME,IR,DR,RI> CR: 28002424 XER: 00000001 SOFTE: 1 CFAR: c0000000007a39c8 TASK = c0000003ee8d5c90[8406] 'rmmod' THREAD: c0000003ee9c4000 CPU: 31 GPR00: c0000000003fc3e8 c0000003ee9c7760 c000000000c789f8 00000000000000ee GPR04: 0000000000000000 00000000000000ef 0000000000004000 0000000000010000 GPR08: 00000000000000be c000000000b22088 c000000000c4c218 00000000007c0000 GPR12: 0000000028002422 c00000000ff26c80 0000000000000000 000001001b0f1b40 GPR16: 00000000100cb9d8 0000000010093088 c000000000cdf910 0000000000000001 GPR20: 0000000000000000 c000000000dbfc00 0000000000000000 c000000000dbfb80 GPR24: c0000003fafc9d80 0000000000000001 000000000001ff80 c0000003f38f7888 GPR28: c000000000ddfc00 0000000000000400 c000000000bd7790 c000000000ddfb80 NIP [c0000000003fc3ec] .dma_debug_device_change+0x22c/0x2b0 LR [c0000000003fc3e8] .dma_debug_device_change+0x228/0x2b0 Call Trace: [c0000003ee9c7760] [c0000000003fc3e8] .dma_debug_device_change+0x228/0x2b0 (unreliable) [c0000003ee9c7840] [c00000000079a098] .notifier_call_chain+0x78/0xf0 [c0000003ee9c78e0] [c0000000000acc20] .__blocking_notifier_call_chain+0x70/0xb0 [c0000003ee9c7990] [c0000000004a9580] .__device_release_driver+0x100/0x140 [c0000003ee9c7a20] [c0000000004a9708] .driver_detach+0x148/0x150 [c0000003ee9c7ac0] [c0000000004a8144] .bus_remove_driver+0xc4/0x150 [c0000003ee9c7b60] [c0000000004aa58c] .driver_unregister+0x8c/0xe0 [c0000003ee9c7bf0] [c0000000004090b4] .pci_unregister_driver+0x34/0xf0 [c0000003ee9c7ca0] [d000000002231194] .qlge_exit+0x1c/0x34 [qlge] [c0000003ee9c7d20] [c0000000000e36d8] .SyS_delete_module+0x1e8/0x290 [c0000003ee9c7e30] [c0000000000098d4] syscall_exit+0x0/0x94 Instruction dump: 7f26cb78 e818003a e87e81a0 e8f80028 e9180030 796b1f24 78001f24 7d6a5a14 7d2a002a e94b0020 483a7595 60000000 <0fe00000> 2fb80000 40de0048 80120050 ---[ end trace 4294f9abdb01031d ]--- Mapped at: [<d000000002222f54>] .ql_update_lbq+0x384/0x580 [qlge] [<d000000002227bd0>] .ql_clean_inbound_rx_ring+0x300/0xc60 [qlge] [<d0000000022288cc>] .ql_napi_poll_msix+0x39c/0x5a0 [qlge] [<c0000000006b3c50>] .net_rx_action+0x170/0x300 [<c000000000081840>] .__do_softirq+0x170/0x300 Signed-off-by: Thadeu Lima de Souza Cascardo <[email protected]> Acked-by: Jitendra Kalsaria <[email protected]> Signed-off-by: David S.

2013-05-13drm/mgag200: Fix writes into MGA1064_PIX_CLK_CTL registerChristopher Harvey1-21/+21
The original line, WREG_DAC(MGA1064_PIX_CLK_CTL_CLK_DIS, tmp); wrote tmp into MGA1064_PIX_CLK_CTL_CLK_DIS, where MGA1064_PIX_CLK_CTL_CLK_DIS is an offset into MGA1064_PIX_CLK_CTL. Change the line to write properly into MGA1064_PIX_CLK_CTL. There were other chunks of code nearby that use the same pattern (but work correctly), so this patch updates them all to use this new (slightly more efficient) write pattern. The WREG_DAC macro was causing the DAC_INDEX register to be set to the same value twice. WREG8(DAC_DATA, foo) takes advantage of the fact that DAC_INDEX is already at the value we want.

2013-05-11emac: Fix EMAC soft reset on 460EX/GTPetri Gynther1-8/+28
Fix EMAC soft reset on 460EX/GT to select the right PHY clock source before and after the soft reset. EMAC with PHY should use the clock from PHY during soft reset. EMAC without PHY should use the internal clock during soft reset. PPC460EX/GT Embedded Processor Advanced User's Manual section 28.10.1 Mode Register 0 (EMACx_MR0) states: Note: The PHY must provide a TX Clk in order to perform a soft reset of the EMAC. If none is present, select the internal clock (SDR0_ETH_CFG[EMACx_PHY_CLK] = 1). After a soft reset, select the external clock. Without the fix, 460EX/GT-based boards with RGMII PHYs attached to EMACs experience EMAC interrupt storm and system watchdog reset when issuing "ifconfig eth0 down" + "ifconfig eth0 up" a few times. The system enters endless loop of serving emac_irq() with EMACx_ISR register stuck at value 0x10000000 (Rx parity error). With the fix, the above issue is no longer observed.
