MT8173 platform use vpu firmware, mt8183/mt8192 will use scp firmware instead, using chip name is not reasonable to separate different firmware architecture. Using firmware type is much better. Signed-off-by:

Using an activation counter to decide when the enable or disable the cec adapter is not the best approach and can lead to race conditions. Change this to determining the current status of the adapter, and enable or disable the adapter accordingly. It now only needs to be called whenever there is a chance that the state changes, and it can handle enabling/disabling monitoring as well if needed. This simplifies the code and it should be a more robust approach as well. Signed-off-by:

If the physical address changes (i.e. becomes invalid, then valid again) while the adapter is still claiming free logical addresses, then trigger a reconfiguration since any claimed LAs may now be stale. Signed-off-by:
-
Hans Verkuil authored
If an adapter is trying to claim a free logical address then it is in the 'is_configuring' state. If during that process the cable is disconnected (HPD goes low, which in turn invalidates the physical address), then cec_adap_unconfigure() is called, and that set the is_configuring boolean to false, even though the thread that's trying to claim an LA is still running. Don't touch the is_configuring bool in cec_adap_unconfigure(), it will eventually be cleared by the thread. By making that change the cec_config_log_addr() function also had to change: it was aborting if is_configuring became false (since that is what cec_adap_unconfigure() did), but that no longer works. Instead check if the physical address is invalid. That is a much more appropriate check anyway. This fixes a bug where the the adapter could be disabled even though the device was still configuring. This could cause POLL transmits to time out. Signed-off-by:

If, while trying to claim a free logical address, a POLL message times out, then abort this process. A CEC_TX_STATUS_TIMEOUT should be handled the same as a CEC_TX_STATUS_ABORTED. This avoids a situation where transmits time out due to a driver or hardware bug and it takes ages before the attempt to find available free logical addresses finishes. Signed-off-by:

The __cec_s_log_addrs() function can configure or unconfigure the adapter. The ioctl handler in cec-api.c will prevent it from being called to configure the adapter if it was already configured (or in the process of configuring). But it can still be called to unconfigure an already unconfigured adapter, and it didn't check for that. This can cause cec_activate_cnt_dec() to be called too often, causing a WARN_ON. Instead first check if adap->log_addrs.num_log_addrs == 0 and return since in that case the adapter is already unconfigured. Signed-off-by:

It's OK to keep the pending pin events when disabling or enabling the 'adapter'. Zeroing this can cause a race condition if this happens when the pin kthread is handling a pin event and calls atomic_dec later, causing work_pin_num_events to become negative. Just leave pending events in the queue, they'll be read eventually. Signed-off-by:

When the adap_enable callback is called the adap->lock is held. When disabling the adapter it attempts to stop the kthread that deals with receiving and transmitting messages. However, kthread_stop waits for the thread to stop, so all that time adap->lock is held. Unfortunately, the kernel thread itself can call functions that take that same lock, so a deadlock can occur. Change the logic to keep the kernel thread running and instead when disabling the adapter, just set the pin to high, go to idle and then to state OFF and disable the interrupt. Only stop the kernel thread when the adapter is deleted. This way disabling the adapter will not wait for anything and the deadlock is avoided. Signed-off-by:

Since usb_register_dev() from imon_init_display() from imon_probe() holds minor_rwsem while display_open() which holds driver_lock and ictx->lock is called with minor_rwsem held from usb_open(), holding driver_lock or ictx->lock when calling usb_register_dev() causes circular locking dependency problem. Since usb_deregister_dev() from imon_disconnect() holds minor_rwsem while display_open() which holds driver_lock is called with minor_rwsem held, holding driver_lock when calling usb_deregister_dev() also causes circular locking dependency problem. Sean Young explained that the problem is there are imon devices which have two usb interfaces, even though it is one device. The probe and disconnect function of both usb interfaces can run concurrently. Alan Stern responded that the driver and USB cores guarantee that when an interface is probed, both the interface and its USB device are locked. Ditto for when the disconnect callback gets run. So concurrent probing/ disconnection of multiple interfaces on the same device is not possible. Therefore, we don't need locks for handling race between imon_probe() and imon_disconnect(). But we still need to handle race between display_open() /vfd_write()/lcd_write()/display_close() and imon_disconnect(), for disconnect event can happen while file descriptors are in use. Since "struct file"->private_data is set by display_open(), vfd_write()/ lcd_write()/display_close() can assume that "struct file"->private_data is not NULL even after usb_set_intfdata(interface, NULL) was called. Replace insufficiently held driver_lock with refcount_t based management. Add a boolean flag for recording whether imon_disconnect() was already called. Use RCU for accessing this boolean flag and refcount_t. Since the boolean flag for imon_disconnect() is shared, disconnect event on either intf0 or intf1 affects both interfaces. But I assume that this change does not matter, for usually disconnect event would not happen while interfaces are in use.

PoC shall be int the range of -2^31 to 2^31 -1 (HEVC spec section 8.3.1 Decoding process for picture order count). The current way to know if an entry in reference picture array is free is to test if PoC = UNUSED_REF. Since UNUSED_REF is defined as '-1' that could lead to decode issue if one PoC also equal '-1'. PoC with value = '-1' exists in conformance test SLIST_B_Sony_9. Change the way unused entries are managed in reference pictures array to avoid using PoC to detect then.

Hantro decoder doesn't take care of the requested and aligned size of the capture buffer. Stop using the bitstream width/height and use capture frame size stored in the context to get the correct values. hantro_hevc_chroma_offset() and hantro_hevc_motion_vectors_offset() are only used in hantro_g2_hevc_dec.c so take the opportunity to move them here. fluster HEVC score goes up from 77 to 85 successful tests (over 147) with this patch.

Hantro G2 post processor is able to down scale decoded frames by a factor of 2, 4 or 8. Add enum_framesizes() ops to postproc_ops structure to enumerate the possible output sizes for a given input resolution. For G2 post-processor use fsize->index (from 0 to 3) as power of 2 divisor. As described in v4l2 documentation return -EINVAL when scaling down isn't possible. fluster scores: 77/147 for HEVC 143/303 for VP9 Signed-off-by:
