We previously emulated a legacy KMS interface, but there was a desire 30 * to move to the atomic KMS interface. The vkms driver did everything we 31 * needed, but we wanted KMS support natively in the driver without buffer 32 * sharing and the ability to support an instance of VKMS per device. We first 33 * looked at splitting vkms into a stub driver and a helper module that other 34 * drivers could use to implement a virtual display, but this strategy ended up 35 * being messy due to driver specific callbacks needed for buffer management. 36 * Ultimately, it proved easier to import the vkms code as it mostly used core 37 * drm helpers anyway. 38 */ 39 40 static const u32 amdgpu_vkms_formats[] = { 41 DRM_FORMAT_XRGB8888, 42 }; 43 44 static enum hrtimer_restart amdgpu_vkms_vblank_simulate(struct hrtimer *timer) 45 { 46 struct amdgpu_crtc *amdgpu_crtc = container_of(timer, struct amdgpu_crtc, vblank_timer); 47 struct drm_crtc *crtc = &amdgpu_crtc->base; 48 struct amdgpu_vkms_output *output = drm_crtc_to_amdgpu_vkms_output(crtc); 49 u64 ret_overrun; 50 bool ret; 51 52 ret_overrun = hrtimer_forward_now(&amdgpu_crtc->vblank_timer, 53 output->period_ns); 54 if (ret_overrun != 1) 55 DRM_WARN("%s: vblank timer overrun\n", __func__); 56 57 ret = drm_crtc_handle_vblank(crtc); 58 if (!ret) 59 DRM_ERROR("amdgpu_vkms failure on handling vblank"); 60 61 return HRTIMER_RESTART; 62 } 63 64 static int amdgpu_vkms_enable_vblank(struct drm_crtc *crtc) 65 { 66 struct drm_device *dev = crtc->dev; 67 unsigned int pipe = drm_crtc_index(crtc); 68 struct drm_vblank_crtc *vblank = &dev->vblank[pipe]; 69 struct amdgpu_vkms_output *out = drm_crtc_to_amdgpu_vkms_output(crtc); 70 struct amdgpu_crtc *amdgpu_crtc = to_amdgpu_crtc(crtc); 71 72 drm_calc_timestamping_constants(crtc, &crtc->mode); 73 74 out->period_ns = ktime_set(0, vblank->framedur_ns); 75 hrtimer_start(&amdgpu_crtc->vblank_timer, out->period_ns, HRTIMER_MODE_REL); 76 77 return 0; 78 } 79 80 static void amdgpu_vkms_disable_vblank(struct drm_crtc *crtc) 81 { 82 struct amdgpu_crtc *amdgpu_crtc = to_amdgpu_crtc(crtc); 83 84 hrtimer_cancel(&amdgpu_crtc->vblank_timer); 85 } 86 87 static bool amdgpu_vkms_get_vblank_timestamp(struct drm_crtc *crtc, 88 int *max_error, 89 ktime_t *vblank_time, 90 bool in_vblank_irq) 91 { 92 struct drm_device *dev = crtc->dev; 93 unsigned int pipe = crtc->index; 94 struct amdgpu_vkms_output *output = drm_crtc_to_amdgpu_vkms_output(crtc); 95 struct drm_vblank_crtc *vblank = &dev->vblank[pipe]; 96 struct amdgpu_crtc *amdgpu_crtc = to_amdgpu_crtc(crtc); 97 98 if (!READ_ONCE(vblank->enabled)) { 99 *vblank_time = ktime_get(); 100 return true; 101 } 102 103 *vblank_time = READ_ONCE(amdgpu_crtc->vblank_timer.node.expires); 104 105 if (WARN_ON(*vblank_time == vblank->time)) 106 return true; 107 108 /* 109 * To prevent races we roll the hrtimer forward before we do any 110 * interrupt processing - this is how real hw works (the interrupt is 111 * only generated after all the vblank registers are updated) and what 112 * the vblank core expects.
