| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | vga-switcheroo with apple-gmux does not switch correctly on my system. The PCI configuration space is not restored correctly, resulting in MSI not working after switch. Only useful item in dmesg is: [ 33.922807] radeon 0000:01:00.0: Refused to change power state, currently in D3 I did some testing, dumping the difference in ms between first succesful switch from D3 to D0, and it seems that there is slightly more than 20 ms difference when the device is re-enabled through vga-switcheroo. So bump the re-enable d3 delay to 20 ms to handle this, which fixes msi not working on my system after switcheroo-ing. Default d3_delay value is PCI_PM_D3_WAIT, 10 ms.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Increasing ref counts of both dma-buf and gem for imported dma-buf come from gem makes memory leak. release function of dma-buf cannot be called because f_count of dma-buf increased by importing gem and gem ref count cannot be decrease because of exported dma-buf. So I add dma_buf_put() for imported gem come from its own gem into each drivers having prime_import and prime_export capabilities. With this, only gem ref count is increased if importing gem exported from gem of same driver.
