2019-04-25libdrm: reduce number of reallocations in drmModeAtomicAddPropertyAdrian Salido1-3/+4
When calling drmModeAtomicAddProperty allocation of memory happens as needed in increments of 16 elements. This can be very slow if there are multiple properties to be updated in an Atomic Commit call. Increase this to as many as can fit in a memory PAGE to avoid having to reallocate memory too often. Also this patch has a small one line perf tweak in drmModeAtomicDuplicate() to only memcpy items to the cursor position in order avoid copying the entire item array if its mostly empty.

2017-04-06Add CRTC ID to vblank eventAnder Conselvan de Oliveira1-8/+16
When using the atomic API, one request can span multiple CRTCs, however one event is generated per CRTC. As we cannot disambiguate the CRTC with user data (since we only have one piece of user data to pass in), newer kernels can include the CRTC ID in the page flip event. Add a new vfunc to dispatch vblank events carrying a CRTC ID to clients who negotiate a higher interface version.

2016-01-07Fix memory leak with drmModeGetConnectorCurrent()Ville Syrjälä1-4/+7
drmModeGetConnectorCurrent() must provide temporary storage for the kernel to fill in at least one mode (asking for !=0 modes is how you prevent the heavyweight probe in the kernel). Currently we malloc that temp storage but we fail to free it before overwriting the pointer with the address of the actual storage we use to store the real mode list we get from the kernel in the second ioctl call. Let's just keep the temporary storage on the stack and thus we avoid the leak and also eliminate some pointless mallocs.

2015-04-14mode: Retrieve only the current information for a ConnectorChris Wilson1-3/+20
Add a new API that allows the caller to skip any forced probing, which may require slow i2c to a remote display, and only report the currently active mode and encoder for a Connector. This is often the information of interest and is much, much faster than re-retrieving the link status and EDIDs, e.g. if the caller only wishes to count the number of active outputs. v2: Fix error path to avoid double free after a failed GETCONNECTOR ioctl. v3: Daniel strongly disapproved of my disjoint in behaviour between GetConnector and GetConnectorCurrent, and considering how best to make a drop in replacement for drmmode_output_init() convinced me keeping the API as consistent as possible was the right approach. v4: Avoid probing on the second calls to GETCONNECTOR for unconnected outputs.
