2019-03-05mm: replace all open encodings for NUMA_NO_NODEAnshuman Khandual1-1/+2
Patch series "Replace all open encodings for NUMA_NO_NODE", v3. All these places for replacement were found by running the following grep patterns on the entire kernel code. Please let me know if this might have missed some instances. This might also have replaced some false positives. I will appreciate suggestions, inputs and review. 1. git grep "nid == -1" 2. git grep "node == -1" 3. git grep "nid = -1" 4. git grep "node = -1" This patch (of 2): At present there are multiple places where invalid node number is encoded as -1. Even though implicitly understood it is always better to have macros in there. Replace these open encodings for an invalid node number with the global macro NUMA_NO_NODE. This helps remove NUMA related assumptions like 'invalid node' from various places redirecting them to a common definition.

2019-03-02habanalabs: adjust Kconfig to fix build errorsOded Gabbay1-1/+2
The driver use the HWMON framework to display various sensors information. Therefore, CONFIG_HWMON must be included to prevent build errors. This patch adds "select HWMON" to the driver's Kconfig file to make sure HWMON is built. In addition, to avoid breaking dependencies, it adds dependency on HAS_IOMEM because HWMON is dependent on HAS_IOMEM.

2019-03-02habanalabs: use %px instead of %p in error printOded Gabbay1-1/+1
When parsing the address of an internal command buffer, the driver prints an error if the buffer's address is not in the range of the device's DRAM or SRAM memory address space. Use %px to print the real address that the user gave the driver and not a hashed value, so the user will get a clue regarding the origin of his error. Note that if the print occurs, the pointer that is printed is a user's virtual address and not some kind of physical address.

2019-02-28habanalabs: soft-reset device if context-switch failsOded Gabbay2-8/+10
This patch fix a bug in the driver, where if the TPC or MME remains in non-IDLE even after all the command submissions are done (due to user bug or malicious user), then future command submissions will fail in the context-switch stage and the driver will remain in "stuck" mode. The fix is to do a soft-reset of the device in case the context-switch fails, because the device should be IDLE during context-switch. If it is not IDLE, then something is wrong and we should reset the compute engines. Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2019-02-28habanalabs: disable CPU access on timeoutsOded Gabbay6-7/+18
This patch provides a workaround for a bug in the F/W where the response time for a request from KMD may take more then 100ms. This could cause the queue between KMD and the F/W to get out of sync. The WA is to: 1. Increase the timeout of ALL requests to 1s. 2. In case a request isn't answered in time, mark the state as "cpu_disabled" and prevent sending further requests from KMD to the F/W. This will eventually lead to a heartbeat failure and hard reset of the device. Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2019-02-28habanalabs: add MMU DRAM default page mappingOmer Shpigelman6-168/+361
This patch provides a workaround for a H/W bug in Goya, where access to RAZWI from TPC can cause PCI completion timeout. The WA is to use the device MMU to map any unmapped DRAM memory to a default page in the DRAM. That way, the TPC will never reach RAZWI upon accessing a bad address in the DRAM. When a DRAM page is mapped by the user, its default mapping is overwritten. Once that page is unmapped, the MMU driver will map that page to the default page. To help debugging, the driver will set the default page area to 0x99 on device initialization.

This patch provides a workaround for a H/W bug in the RAZWI logger in Goya. The logger doesn't recognize the initiator correctly and as a result, accesses from one initiator are reported that were coming from a different initiator. The WA is to print the error information from the event entries we receive without looking at the RAZWI logger at all.

CL2600/CL2800 servers leveraged Proliant hardware but are targeted to a different market segment and come with a different firmware base. Based upon targeted market needs, the servers de-featured certain aspects of iLO. As a result, hpilo driver still claims the hardware but is not functional, so we decided to blacklist it with SSID 0x0289 to reduce confusion to customers.

2019-02-27misc: hpilo: Exclude unsupported device via blacklistMatt Hsiao1-3/+9
Instead of having explicit if statements excluding devices, use a pci_device_id table of devices to blacklist. HPE will put out minor updates to the iLO using the same device info except for the subsystem device id. hpilo driver takes the approach to claim based upon {Vendor, Device, SubVendor} and it allows old software to work on new hardware without patching. As our primary way to support our customers is via distros, the patching process could take months to go upstream and then backported to multiple releases of multiple distros. This approach worked fairly well as this is only the second time in 10+ years that we need to blacklist an instance.

2019-02-27habanalabs: allow memory allocations larger than 4GBOded Gabbay2-7/+5
This patch increase the size field in the uapi structure of the Memory IOCTL from 32-bit to 64-bit. This is to allow the user to allocate and/or map memory in chunks that are larger then 4GB. Goya's device memory (DRAM) can be up to 16GB, and for certain topologies, the user may want an allocation that is larger than 4GB. This change doesn't break current user-space because there was a "pad" field in the uapi structure right after the size field. Changing the size field to be 64-bit and removing the pad field maintains compatibility with current user-space.
