2015-05-20drm/i915: Don't overwrite (e)DP PLL selection on SKLAnder Conselvan de Oliveira3-2/+18
In the following commit, the place where the contents of dpll_hw_state in crtc_state where zeroed was changed. Prior to that commit, it happened when the new state was allocated, but now that happens just before the call the .crtc_compute_clock() hook. The DP code for SKL, however, sets up the (private) PLL in the encoder compute config function that has already run by the time that memset() is reached, causing the previous value to be lost. This patch fixes the issue by moving the memset() down the call chain, so that it is only called if the values in dpll_hw_state are going to be updated. commit 4978cc93d9ac240b435ce60431aef24239b4c270 Author: Ander Conselvan de Oliveira <[email protected]> Date: Tue Apr 21 17:13:21 2015 +0300 drm/i915: Preserve shared DPLL information in new pipe_config Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=90462 Signed-off-by: Ander Conselvan de Oliveira <[email protected]> Reviewed-by: Damien Lespiau <[email protected]> Reported-and-tested-by: Tvrtko Ursulin <[email protected]> Signed-off-by: Daniel Vetter <[email protected]>
2015-05-20drm/i915/bios: be more explicit about discarding iomem address spaceJani Nikula1-7/+14
Add one explicit discard of __iomem address space qualifier in validate_vbt(), and respect it otherwise. This adds clarity in the code, and reduces the sparse warnings from the module to just one. Quoting Daniel, "The vbt really is plain old memory. Except that it's reserved in the e820 table as something special and hence treated as io range by the kernel. But it is memory, hence casting away the __iomem is imo the right approach." Signed-off-by: Jani Nikula <[email protected]> Signed-off-by: Daniel Vetter <[email protected]>

2015-05-20drm/i915: Fix race on unreferencing the wrong mmio-flip-requestChris Wilson3-24/+25
As we perform the mmio-flip without any locking and then try to acquire the struct_mutex prior to dereferencing the request, it is possible for userspace to queue a new pageflip before the worker can finish clearing the old state - and then it will clear the new flip request. The result is that the new flip could be completed before the GPU has finished rendering.

This patch adds a new kernel module parameter to amdkfd, called send_sigterm. This parameter specifies whether amdkfd should send the SIGTERM signal to an HSA process, when the following conditions occur: 1. The GPU triggers an exception regarding a kernel that was issued by this process. 2. The HSA process isn't waiting on an event that handles this exception. The default behavior is not to send a SIGTERM and suffice with a dmesg error print. Reviewed-by: Ben Goz <[email protected]> Signed-off-by: Oded Gabbay <[email protected]>

2015-05-19drm/amdkfd: Add memory exception handlingAlexey Skidanov4-9/+187
This patch adds Peripheral Page Request (PPR) failure processing and reporting. Bad address or pointer to a system memory block with inappropriate read/write permission cause such PPR failure during a user queue processing. PPR request handling is done by IOMMU driver notifying AMDKFD module on PPR failure. The process triggering a PPR failure will be notified by appropriate event or SIGTERM signal will be sent to it. v3: - Change all bool fields in struct kfd_memory_exception_failure to uint32_t Signed-off-by: Alexey Skidanov <[email protected]> Signed-off-by: Oded Gabbay <[email protected]>
2015-05-19drm/amdkfd: Add the events moduleAndrew Lewycky10-5/+1074
This patch adds the events module (kfd_events.c) and the interrupt handle module for Kaveri (cik_event_interrupt.c). The patch updates the interrupt_is_wanted(), so that it now calls the interrupt isr function specific for the device that received the interrupt. That function(implemented in cik_event_interrupt.c) returns whether this interrupt is of interest to us or not. The patch also updates the interrupt_wq(), so that it now calls the device's specific wq function, which checks the interrupt source and tries to signal relevant events. v2: Increase limit of signal events to 4096 per process Remove bitfields from struct cik_ih_ring_entry Rename radeon_kfd_event_mmap to kfd_event_mmap Add debug prints to allocate_free_slot and allocate_signal_page Make allocate_event_notification_slot return a correct value Add warning prints to create_signal_event Remove error print from IOCTL path Reformatted debug prints in kfd_event_mmap Map correct size (as received from mmap) in kfd_event_mmap v3: Reduce limit of signal events back to 256 per process Fix allocation of kernel memory for signal events Signed-off-by: Andrew Lewycky <[email protected]> Signed-off-by: Oded Gabbay <[email protected]>

- AMDKFD_IOC_CREATE_EVENT: Creates a new event of a specified type - AMDKFD_IOC_DESTROY_EVENT: Destroys an existing event - AMDKFD_IOC_SET_EVENT: Signal an existing event - AMDKFD_IOC_RESET_EVENT: Reset an existing event - AMDKFD_IOC_WAIT_EVENTS: Wait on event(s) until they are signaled v2: - Move the limit of the signal events to kfd_ioctl.h so it can be used by userspace v3: - Change all bool fields in struct kfd_memory_exception_failure to uint32_t Signed-off-by: Andrew Lewycky <[email protected]> Signed-off-by: Oded Gabbay <[email protected]>
