This patch deinlines indirect register accessor functions. These functions perform two mmio accesses, framed by spin lock/unlock. Spin lock/unlock by itself takes more than 50 cycles in ideal case (if lock is exclusively cached on current CPU). With this .config: http://busybox.net/~vda/kernel_config, after uninlining these functions have sizes and callsite counts as follows: r600_uvd_ctx_rreg: 111 bytes, 4 callsites r600_uvd_ctx_wreg: 113 bytes, 5 callsites eg_pif_phy0_rreg: 106 bytes, 13 callsites eg_pif_phy0_wreg: 108 bytes, 13 callsites eg_pif_phy1_rreg: 107 bytes, 13 callsites eg_pif_phy1_wreg: 108 bytes, 13 callsites rv370_pcie_rreg: 111 bytes, 21 callsites rv370_pcie_wreg: 113 bytes, 24 callsites r600_rcu_rreg: 111 bytes, 16 callsites r600_rcu_wreg: 113 bytes, 25 callsites cik_didt_rreg: 106 bytes, 10 callsites cik_didt_wreg: 107 bytes, 10 callsites tn_smc_rreg: 106 bytes, 126 callsites tn_smc_wreg: 107 bytes, 116 callsites eg_cg_rreg: 107 bytes, 20 callsites eg_cg_wreg: 108 bytes, 52 callsites Functions r100_mm_rreg() and r100_mm_rreg() have a fast path and a locked (slow) path.

If we have more than one CRTCs in a group pre-associate planes 0-3 with CRTC 0 and planes 4-7 with CRTC 1 to minimize flicker occurring when the association is changed. The pre-association could be controlled by a module parameter if needed. Signed-off-by:Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

The number of CRTCs in a group is only used to implement plane initialization for now, but is also needed to implement pre-association of planes to CRTCs. Store it in the group structure instead of computing it on demand. Signed-off-by: -
Laurent Pinchart authored
Hardware planes are driven by the timing generator of the CRTC they are associated to. Changing the association requires restarting the CRTC group that the plane belongs to, resulting in flicker on the other CRTC. To avoid flicker as much as possible, try to allocate planes first from the free planes already associated with the target CRTC. If allocation fails then fall back to allocation from all free planes.

Changing the plane to CRTC associations requires restarting the CRTC group, creating visible flicker. Mitigate the issue by changing plane association only when a plane becomes enabled, not when it get disabled. Signed-off-by: -

The ADV7511 is probed before its slave encoder init function associates it with an encoder. This creates a time window during which hot plug detection interrupts can occur with an encoder, resulting in a crash in the IRQ handler. Fix this by ignoring hot plug detection IRQs when no encoder is associated yet. Signed-off-by:

- Add the interrupts & events modules, including new IOCTLs to create and wait on events. The HSA RT open source stack is mainly using events to know when a dispatched work has been completed. In addition, this module is a pre-requisite for the next module I'm going to upstream - debugger support This module also handles H/W exceptions, such as memory exception received through the IOMMUv2 H/W and Bad Opcode exception receieved from the GPU. - Adding a new kernel module parameter to let the user decide whether he wants to receive a SIGTERM when a memory exception occurs inside the GPU kernel and the HSA application doesn't wait on an appropriate event, or if he just want to receive notification about this event in dmesg. The default is the latter. - Additional improvements for SDMA code - Update my email address in Maintainers file. * tag 'drm-amdkfd-next-2015-05-19' of git://people.freedesktop.org/~gabbayo/linux: drm/amdkfd: change driver version to 0.7.2 drm/amdkfd: Implement events IOCTLs drm/amdkfd: Add module parameter of send_sigterm drm/amdkfd: Add bad opcode exception handling drm/amdkfd: Add memory exception handling drm/amdkfd: Add the events module drm/amdkfd: add events IOCTL set definitions drm/amdkfd: Add interrupt handling module drm/radeon: Add init interrupt kfd->kgd interface MAINTAINERS: update amdkfd Oded's email address drm/amdkfd: make the sdma vm init to be asic specific drm/amdkfd: Use new struct for asic specific ops drm/amdkfd: reformat some debug prints drm/amdkfd: Remove unessary void pointer cast

Scattering of random drm core patches.

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:

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:

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:
