* gpu: nvgpu: make .tsg_unbind_channel one layer lowerRichard Zhao2018-01-31
| | | | | | | | | | | | | | | | | | | | | | | | | The message to tell RM server to unbind channel has to be sent after client unbinds the channel and before client calls tsg release. The channel has to belong to a tsg on RM server before client submit a runlist to remove the channel. Or there's a bare channel problem. By moving .tsg_unbind_channl one layer lower, gk20a_tsg_unbind_channel() will be common functions for all chip, and it'll call tsg release after call .tsg_unbind_channel. So vgpu won't need to worry about tsg was released before sending msg to RM server.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Patch 7240b3c2 enabled secure allocation for gv11b But since we allocate secure buffers in poweron path, and secure allocation needs GPU to be in off state, this results in deadlock in poweron path To solve this, we already cause early VPR resize for older chips by calling gk20a_tegra_secure_page_alloc() from late_probe Implement same for gv11b.

| | | | | | | | | | | | | | | | | | These '\n' were leftover from the previous debugging macro usage which did no add the '\n' automagically. However, once swapped over to the nvgpu logging system the '\n' is added and no longer needs to be present in the code. This did require one extra modification though to keep things consistent. The __alloc_pstat() macro, used for sending output either to a seq_file or the terminal, needed to add the '\n' for seq_printf() calls and the '\n' had to be deleted in the C files.

This is no longer the case if railgating has been allowed for a channel via the deterministic options ioctl which also causes the channel to drop the power ref that it holds otherwise during its lifetime. All this is happening inside the deterministic_busy rwsem, which also guards the ioctl changing those deterministic option states.

Some userspace APIs to make sure that we're ready by testing g->gr.sw_ready, but this flag is set in the middle of bootup; there are other things after gr initialization. Add a new flag that is enabled after bootup is fully complete at the end of finalize_poweron, and change the checks in user API paths to test the new flag only. These checks are only in the ioctl paths for ctrl, dbg and tsg, and in the ctrl device's opening path. The gr.sw_ready flag is still left there to signify whether just gr has had its bookkeeping initialized.

| | | | | | | | | | | | | | | | | | | | | In the buddy allocator use the actual size of the PDE to determine the pte_blk_order field which is used to determine what page size a buddy has (or doesn't). Previously this was just set as the large page size times 1024 which would over allocate PDE ranges for Pascal+ chips. This caused userspace, which was using the real PDE size, to sometime allocate small and large pages in what the buddy allocator mistakenly thought was one PDE.
