This patch adds workflow files for ci: [sync.yml] - The workflow file for scheduled work - Sync the repo with upstream repo and rebase the workflow branch - Review the patches in the patchwork and creates the PR if needed [ci.yml] - The workflow file for CI tasks - Run CI tests when PR is created Signed-off-by: Tedd Ho-Jeong An <tedd.an@intel.com>
This replaces the bzcafe action with bluez/action-ci so we can maintain everything in the github bluez organization Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>
This attempts to sync every 5 minutes instead of 30. Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>
bluez/action-ci uses master as default branch for workflow which is incorrect for kernel Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>
The CI action now creates individual GitHub Check Runs per test, which requires 'checks: write' permission on the GITHUB_TOKEN. Also make the pull_request trigger types explicit to include 'reopened', allowing CI to be retriggered by closing and reopening a PR.
btintel_pcie_set_dxstate() falls back to checking the controller state via btintel_pcie_in_d3/d0() when the alive interrupt is missed. However, these helpers read boot_stage_cache, which is only updated by the interrupt handler. As such, if the interrupt was missed, the cache is stale and the fallback check always fails, exhausting all retries and returning -EBUSY, causing suspend to abort. The fix involves re-reading the hardware register before the fallback state check, consistent with btintel_pcie_resume(). Fixes: e57362f ("Bluetooth: btintel_pcie: Add support for _suspend() / _resume()") Signed-off-by: Vladimir V. Kondratyev <vladimirkondratyev2@gmail.com>
