Subject: [PATCH v6 0/2] ACPI / APEI: Add support to notify the vendor specific HW errors
Date: Wed, 25 Mar 2020 16:42:21 +0000
Message-ID: <20200325164223.650-1-shiju.jose@huawei.com> (raw)
In-Reply-To: <Shiju Jose>

Presently the vendor drivers are unable to do the recovery for the
vendor specific recoverable HW errors, reported to the APEI driver
in the vendor defined sections, because APEI driver does not support
reporting the same to the vendor drivers.

This patch set
1. add an interface to the APEI driver to enable the vendor
drivers to register the event handling functions for the corresponding
vendor specific HW errors and report the error to the vendor driver.

2. add driver to handle HiSilicon hip08 PCIe controller's errors
   which is an example application of the above APEI interface.

Changes:

V6:
1. Fix few changes in the patch subject line suggested by Bjorn Helgaas.

V5:
1. Fix comments from James Morse.
1.1 Changed the notification method to use the atomic_notifier_chain.
1.2 Add the error handled status for the user space.  

V4:
1. Fix for the smatch warning in the PCIe error driver:
   warn: should '((((1))) << (9 + i))' be a 64 bit type?
   if (err->val_bits & BIT(HISI_PCIE_LOCAL_VALID_ERR_MISC + i))
	^^^ This should be BIT_ULL() because it goes up to 9 + 32.

V3:
1. Fix the comments from Bjorn Helgaas.

V2:
1. Changes in the HiSilicon PCIe controller's error handling driver
   for the comments from Bjorn Helgaas.
   
2. Changes in the APEI interface to support reporting the vendor error
   for module with multiple devices, but use the same section type.
   In the error handler will use socket id/sub module id etc to distinguish
   the device.

V1:  
1. Fix comments from James Morse.

2. add driver to handle HiSilicon hip08 PCIe controller's errors,
   which is an application of the above interface.
