New asics support non-privileged IBs. This allows us to skip IB checking in the driver since the hardware will check the command buffers for us. When using non-privileged IBs, if the CP encounters an illegal register in the command stream, it will halt and generate an interrupt. The CP needs to be reset to continue. For now just do a full GPU reset when this happens. Signed-off-by: NAlex Deucher <alexander.deucher@amd.com>

This was incorrectly introduced in: 92db7f6c http://lists.freedesktop.org/archives/dri-devel/2011-December/017717.html However, the off by 2 was due to adding the version twice.

So the total would be: (0x82 + 0x2 + 0xD) + 0x1f6 = 0x287 -0x287 = 0x79 - properly emit the AVI infoframe version. This was not being emitted previous which is probably what caused the issue above.

Commit 10a7a077 ("xen: tmem: enable Xen tmem shim to be built/loaded as a module") allows the tmem module to be loaded any time. For this work the frontswap API had to be able to asynchronously to call tmem_frontswap_init before or after the swap image had been set. That was added in git commit 905cd0e1 ("mm: frontswap: lazy initialization to allow tmem backends to build/run as modules"). Which means we could do this (The common case): modprobe tmem [so calls frontswap_register_ops, no ->init] modifies tmem_frontswap_poolid = -1 swapon /dev/xvda1 [__frontswap_init, calls -> init, tmem_frontswap_poolid is < 0 so tmem hypercall done] Or the failing one: swapon /dev/xvda1 [calls __frontswap_init, sets the need_init bitmap] modprobe tmem [calls frontswap_register_ops, -->init calls, finds out tmem_frontswap_poolid is 0, does not make a hypercall. Later in the module_init, sets tmem_frontswap_poolid=-1] Which meant that in the failing case we would not call the hypercall to initialize the pool and never be able to make any frontswap backend calls. Moving the frontswap_register_ops after setting the tmem_frontswap_poolid fixes it. Signed-off-by: NKonrad Rzeszutek Wilk <konrad.wilk@oracle.com> Reviewed-by: NBob Liu <bob.liu@oracle.com>

In commit 53d3b4d7 Author: Egbert Eich <eich@suse.de> Date: Tue Jun 4 17:13:21 2013 +0200 drm/i915/sdvo: Use &intel_sdvo->ddc instead of intel_sdvo->i2c for DDC Egbert Eich fixed a long-standing bug where we simply used a non-working i2c controller to read the EDID for SDVO-LVDS panels. Unfortunately some machines seem to not be able to cope with the mode provided in the EDID. Specifically they seem to not be able to cope with a 4x pixel mutliplier instead of a 2x one, which seems to have been worked around by slightly changing the panels native mode in the VBT so that the dotclock is just barely above 50MHz. Since it took forever to notice the breakage it's fairly safe to assume that at least for SDVO-LVDS panels the VBT contains fairly sane data. So just switch around the order and use VBT modes first. v2: Also add EDID modes just in case, and spell Egbert correctly. v3: Elaborate a bit more about what's going on on Chris' machine.

sdvo->hotplug_active is initialised during intel_sdvo_setup_outputs(), and so we never enabled the hotplug interrupts on SDVO as we were checking too early.

In commit bc09c219 "Fix finding overflowed PMC in interrupt" we added a printk() to the PMU exception handler. Unfortunately that is not safe. The problem is that the PMU exception may run even when interrupts are soft disabled, aka NMI context. We do this so that we can profile parts of the kernel that have interrupts soft-disabled. But by calling printk() from the exception handler, we can potentially deadlock in the printk code on logbuf_lock, eg: [c00000038ba575c0] c000000000081928 .vprintk_emit+0xa8/0x540 [c00000038ba576a0] c0000000007bcde8 .printk+0x48/0x58 [c00000038ba57710] c000000000076504 .perf_event_interrupt+0x2d4/0x490 [c00000038ba57810] c00000000001f6f8 .performance_monitor_exception+0x48/0x60 [c00000038ba57880] c0000000000032cc performance_monitor_common+0x14c/0x180 --- Exception: f01 (Performance Monitor) at c0000000007b25d4 ._raw_spin_lock_irq +0x64/0xc0 [c00000038ba57bf0] c00000000007ed90 .devkmsg_read+0xd0/0x5a0 [c00000038ba57d00] c0000000001c2934 .vfs_read+0xc4/0x1e0 [c00000038ba57d90] c0000000001c2cd8 .SyS_read+0x58/0xd0 [c00000038ba57e30] c000000000009d54 syscall_exit+0x0/0x98 --- Exception: c01 (System Call) at 00001fffffbf6f7c SP (3ffff6d4de10) is in userspace Fix it by making sure we only call printk() when we are not in NMI context.

When introducing support for DABRX in 4474ef05, we broke older 32-bit CPUs that don't have that register. Some CPUs have a DABR but not DABRX. Configuration are: - No 32bit CPUs have DABRX but some have DABR. - POWER4+ and below have the DABR but no DABRX. - 970 and POWER5 and above have DABR and DABRX. - POWER8 has DAWR, hence no DABRX. This introduces CPU_FTR_DABRX and sets it on appropriate CPUs. We use the top 64 bits for CPU FTR bits since only 64 bit CPUs have this. Processors that don't have the DABRX will still work as they will fall back to software filtering these breakpoints via perf_exclude_event().

RTAS token "ibm,get-config-addr-info" or ibm,get-config-addr-info2" are used to retrieve the PE address according to PCI address, which made up of domain/bus/slot/function. If we don't have those 2 tokens, the domain/bus/slot/function would be used as the address for EEH RTAS operations. Some older f/w might not have those 2 tokens and that blocks the EEH functionality to be initialized. It was introduced by commit e2af155c ("powerpc/eeh: pseries platform EEH initialization"). The patch skips the check on those 2 tokens so we can bring up EEH functionality successfully. And domain/bus/slot/function will be used as address for EEH RTAS operations.

But after commit 6c5705fe (powerpc/PCI: get rid of device resource fixups) the pcibios_fixup_resources is invoked after the bus address was translated to linux resource. So the value of res->start is resource address. And since the resource and bus address may be different, we should translate it to the bus address before doing the check.
