2021-03-31drm/amdgpu: Set a suitable dev_info.gart_page_sizeHuacai Chen
In Mesa, dev_info.gart_page_size is used for alignment and it was set to AMDGPU_GPU_PAGE_SIZE(4KB). However, the page table of AMDGPU driver requires an alignment on CPU pages. So, for non-4KB page system, gart_page_size should be max_t(u32, PAGE_SIZE, AMDGPU_GPU_PAGE_SIZE).

2021-03-31drm/amdkfd: dqm fence memory corruptionQu Huang
Amdgpu driver uses 4-byte data type as DQM fence memory, and transmits GPU address of fence memory to microcode through query status PM4 message. However, query status PM4 message definition and microcode processing are all processed according to 8 bytes. Fence memory only allocates 4 bytes of memory, but microcode does write 8 bytes of memory, so there is a memory corruption. Changes since v1: * Change dqm->fence_addr as a u64 pointer to fix this issue, also fix up query_status and amdkfd_fence_wait_timeout function uses 64 bit fence value to make them consistent.

2021-04-01bus: mhi: core: Move to polling method to wait for MHI readyBhaumik Bhatt
In certain devices, it is likely that there is no incoming MHI interrupt for a transition to MHI READY state. One such example is the move from Pass Through to an SBL or AMSS execution environment. In order to facilitate faster bootup times as there is no need to wait until timeout_ms completes, MHI host can poll every 25 milliseconds to check if device has entered MHI READY until a maximum timeout of twice the timeout_ms is reached.

2021-03-31bus: mhi: core: Wait for MHI READY state in most scenariosBhaumik Bhatt
When moving from SYS_ERROR transition to a different execution environment, MHI host relies on the BHI register read to spawn the next image download or wait for READY -> M0 states. The device can at times move the execution environment to mission mode when a pass through is expected, which can result in a stall. Initiate a wait for MHI READY and write M0 such that the device can proceed with state change event updates for any new execution environment being entered. This allows us to remove conditionals in handling firmware load for PBL modes and keeps the execution environment out of the picture as it can change at any time.

MHI WWAN modems support downloading firmware to NAND or eMMC using Firehose protocol with process as follows: 1. Modem boots up, enters AMSS execution environment and the device later enters EDL (Emergency Download) mode through any mechanism host can use such as a diag command. 2. Modem enters SYS_ERROR, MHI host handles SYS_ERROR transition. 3. EDL image for device to enter 'Flash Programmer' execution environment is then flashed via BHI interface from host. 4. Modem enters MHI READY -> M0 and sends the Flash Programmer execution environment change to host. 5. Following that, EDL/FIREHOSE channels (34, 35) are made available from the host. 6.

2021-03-31bus: mhi: core: Handle EDL mode entry appropriatelyBhaumik Bhatt
Device entering EDL or Emergency Download Mode will be in a SYS_ERROR MHI state. This requires MHI host to proceed with the EDL image download over BHI before device can enter an MHI READY state and proceed with further bootup. Allow this to be handled by relying on the execution environment check after SYS_ERROR processing to determine whether to wait for an MHI READY or download the EDL image over BHI after moving MHI PM state to Power on Reset internally. This way handling is contained well within the MHI core driver and helps pave the way for Flash Programmer execution environment functionality.

2021-03-31phy: cadence: Sierra: Fix PHY power_on sequenceKishon Vijay Abraham I
Commit 44d30d622821d ("phy: cadence: Add driver for Sierra PHY") de-asserts PHY_RESET even before the configurations are loaded in phy_init(). However PHY_RESET should be de-asserted only after all the configurations has been initialized, instead of de-asserting in probe. Fix it here.

2021-03-30ACPI: scan: Fix _STA getting called on devices with unmet dependenciesHans de Goede
Commit 71da201f38df ("ACPI: scan: Defer enumeration of devices with _DEP lists") dropped the following 2 lines from acpi_init_device_object(): /* Assume there are unmet deps until acpi_device_dep_initialize() runs */ device->dep_unmet = 1; Leaving the initial value of dep_unmet at the 0 from the kzalloc(). This causes the acpi_bus_get_status() call in acpi_add_single_object() to actually call _STA, even though there maybe unmet deps, leading to errors like these: [ 0.123579] ACPI Error: No handler for Region [ECRM] (00000000ba9edc4c) [GenericSerialBus] (20170831/evregion-166) [ 0.123601] ACPI Error: Region GenericSerialBus (ID=9) has no handler (20170831/exfldio-299) [ 0.123618] ACPI Error: Method parse/execution failed \_SB.I2C1.BAT1._STA, AE_NOT_EXIST (20170831/psparse-550) Fix this by re-adding the dep_unmet = 1 initialization to acpi_init_device_object() and modifying acpi_bus_check_add() to make sure that dep_unmet always gets setup there, overriding the initial 1 value. This re-fixes the issue initially fixed by commit 63347db0affa ("ACPI / scan: Use acpi_bus_get_status() to initialize ACPI_TYPE_DEVICE devs"), which introduced the removed "device->dep_unmet = 1;" statement. This issue was noticed; and the fix tested on a Dell Venue 10 Pro 5055. Fixes: 71da201f38df ("ACPI: scan: Defer enumeration of devices with _DEP lists") Suggested-by: Rafael J.
