* gpu: host1x: Improve debug disassembly formattingMikko Perttunen2017-10-205-30/+61
| | | | | | | | | | | | | | | The host1x driver prints out "disassembly" dumps of the command FIFO and gather contents on submission timeouts. However, the output has been quite difficult to read with unnecessary newlines and occasional missing parentheses. Fix these problems by using pr_cont to remove unnecessary newlines and by fixing other small issues.

* gpu: host1x: syncpt: Request syncpoints per clientThierry Reding2017-10-206-13/+13
| | | | | | | | | | | | | | Rather than request syncpoints for a struct device *, request them for a struct host1x_client *. This is important because subsequent patches are going to break the assumption that host1x will always be the parent for devices requesting a syncpoint. It's also a more natural choice because host1x clients are really the only ones that will know how to deal with syncpoints. Note that host1x clients are always guaranteed to be children of host1x, regardless of their location in the device tree. Signed-off-by: Thierry Reding <treding@nvidia.com>

This allows us to avoid needing to read the GIC mask registers and perform a bitwise and of their values with the pending & pcpu_masks. Unfortunately this didn't quite work for IPIs, which were mapped to a particular CPU/VP during initialisation but never set the affinity or effective_affinity fields of their struct irq_desc. This led to them losing their affinity when gic_unmask_irq() was called for them, and they'd all become affine to cpu0. Fix this by: 1) Setting the effective affinity of interrupts in gic_shared_irq_domain_map(), which is where we actually map an interrupt to a CPU/VP. This ensures that the effective affinity mask is always valid, not just after explicitly setting affinity. 2) Using an interrupt's effective affinity when unmasking it, which prevents gic_unmask_irq() from unintentionally changing which pcpu_mask includes an interrupt.

Now, after an IOP reset, aacraid immediately start polling a register to verify the reset is complete. This behavior cause regressions on the reset path in PowerPC (at least). Since the delay after the IOP reset was removed by the aforementioned patch, the fact driver just starts to read a register instantly after the reset was issued (by writing in another register) "corrupts" the reset procedure, which ends up failing all the time. The issue highly impacted kdump on PowerPC, since on kdump path we proactively issue a reset in adapter (through the reset_devices kernel parameter). This patch (re-)adds a delay right after IOP reset is issued. Empirically we measured that 3 seconds is enough, but for safety reasons we delay for 5s (and since it was 30s before, 5s is still a small amount). For reference, without this patch we observe the following messages on kdump kernel boot process: [ 76.294] aacraid 0003:01:00.0: IOP reset failed [ 76.294] aacraid 0003:01:00.0: ARC Reset attempt failed [ 86.524] aacraid 0003:01:00.0: adapter kernel panic'd ff.

As SmartIOC-2000 does not support volumes using 4Kn drives, use the intended option flag AAC_OPT_NEW_COMM_64 to determine support for volumes greater than 2T.
