If we have native control of AER, set the following error reporting enable bits: - Correctable Error Reporting Enable - Non-Fatal Error Reporting Enable - Fatal Error Reporting Enable - Unsupported Request Reporting Enable Note that these bits are all in the Device Control register and are not AER-specific. This affects all devices with an AER capability, including hot-added devices. Please note that this change is quite invasive, as error reporting now will be enabled for all available PCIe Endpoints, which was previously not the case. When "pci=noaer" is selected, error reporting stays disabled of course.

AER reporting is currently disabled in the DevCtl registers of all non Root Port PCIe devices on systems using pcie_ports_native || host->native_aer, disabling AER completely in such systems. This is because 2bd50dd8 ("PCI: PCIe: Disable PCIe port services during port initialization"), added a call to pci_disable_pcie_error_reporting() *after* the AER setup was completed for the PCIe device tree. Here a longer analysis about the current status of AER enabling / disabling upon bootup provided by Bjorn: pcie_portdrv_probe pcie_port_device_register get_port_device_capability pci_disable_pcie_error_reporting clear CERE NFERE FERE URRE # <-- disable for RP USP DSP pcie_device_init device_register # new AER service device aer_probe aer_enable_rootport # RP only set_downstream_devices_error_reporting set_device_error_reporting # self (RP) if (RP || USP || DSP) pci_enable_pcie_error_reporting set CERE NFERE FERE URRE # <-- enable for RP pci_walk_bus set_device_error_reporting if (RP || USP || DSP) pci_enable_pcie_error_reporting set CERE NFERE FERE URRE # <-- enable for USP DSP In a typical Root Port -> Endpoint hierarchy, the above: - Disables Error Reporting for the Root Port, - Enables Error Reporting for the Root Port, - Does NOT enable Error Reporting for the Endpoint because it is not a Root Port or Switch Port. In a deeper Root Port -> Upstream Switch Port -> Downstream Switch Port -> Endpoint hierarchy: - Disables Error Reporting for the Root Port, - Enables Error Reporting for the Root Port, - Enables Error Reporting for both Switch Ports, - Does NOT enable Error Reporting for the Endpoint because it is not a Root Port or Switch Port, - Disables Error Reporting for the Switch Ports when pcie_portdrv_probe() claims them. AER does not re-enable it because these are not Root Ports. Remove this call to pci_disable_pcie_error_reporting() from get_port_device_capability(), leaving the already enabled AER configuration intact. With this change, AER is enabled in the Root Port and the PCIe switch upstream and downstream ports. Only the PCIe Endpoints don't have AER enabled yet. A follow-up patch will take care of this Endpoint enabling.

When a device is already unplugged by pciehp by the time the AER handler is invoked, the PCIe device will already be in the pci_channel_io_perm_failure state. In that case simply return PCI_ERS_RESULT_DISCONNECT instead of trying to do a state transition that will fail. Also untangle the state transition failure from the lack of methods to improve the debugging output in case it happens again.

The bluetooth code uses our bitmap infrastructure for the two bits (!) of connection setup flags, and in the process causes odd problems when it converts between a bitmap and just the regular values of said bits. It's completely pointless to do things like bitmap_to_arr32() to convert a bitmap into a u32. It shoudln't have been a bitmap in the first place. The reason to use bitmaps is if you have arbitrary number of bits you want to manage (not two!), or if you rely on the atomicity guarantees of the bitmap setting and clearing. The code could use an "atomic_t" and use "atomic_or/andnot()" to set and clear the bit values, but considering that it then copies the bitmaps around with "bitmap_to_arr32()" and friends, there clearly cannot be a lot of atomicity requirements. So just use a regular integer. In the process, this avoids the warnings about erroneous use of bitmap_from_u64() which were triggered on 32-bit architectures when conversion from a u64 would access two words (and, surprise, surprise, only one word is needed - and indeed overkill - for a 2-bit bitmap). That was always problematic, but the compiler seems to notice it and warn about the invalid pattern only after commit 0a97953f ("lib: add bitmap_{from,to}_arr64") changed the exact implementation details of 'bitmap_from_u64()', as reported by Sudip Mukherjee and Stephen Rothwell.

mod->name is set to the ELF filename with the suffix ".o" stripped. The current code calls strdup() and free() to manipulate the string, but a simpler approach is to pass new_module() with the name length subtracted by 2. Also, check if the passed filename ends with ".o" before stripping it. The current code blindly chops the suffix: tmp[strlen(tmp) - 2] = '\0' It will cause buffer under-run if strlen(tmp) < 2; Signed-off-by:

scripts/Makefile.build and scripts/link-vmlinux.sh have similar setups for the objtool arguments. It was difficult to factor out them because all the vmlinux build rules were written in a shell script. It is somewhat tedious to touch the two files every time a new objtool option is supported. To reduce the code duplication, move the objtool for vmlinux.o into scripts/Makefile.vmlinux_o. Then, move the common macros to Makefile.lib so they are shared between Makefile.build and Makefile.vmlinux_o. Signed-off-by:

Merge tag 'perf-tools-for-v5.19-2022-06-04' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux Pull more perf tools updates from Arnaldo Carvalho de Melo: - Synthesize task events for pre-existing threads when using 'perf lock --threads', as we need to show task names. - Fix unwinding with ld.lld (>= version 10.0) linked objects, where .eh_frame_hdr and .text are in different PT_LOAD program headers, which makes perf record --call-graph dwarf fail with such obkects. - Check if 'perf record' hangs in the ARM SPE (Statistical Profiling Extensions) 'perf test' entry when recording a workload with forks. - Trace physical address for Arm SPE events, needed for 'perf c2c' to locate the memory node for samples. - Fix sorting in percent_rmt_hitm_cmp() in 'perf c2c'. - Further support for Intel hybrid systems in the evlist and 'perf record' code. - Update IBM s/390 vendor event JSON tables. - Add metrics (JSON) for Intel Sapphirerapids. - Update metrics for Intel Alderlake. - Correct typo of sysf 'event_source' directory in the documentation. * tag 'perf-tools-for-v5.19-2022-06-04' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux: perf vendor events intel: Update metrics for Alderlake perf vendor events intel: Add metrics for Sapphirerapids perf c2c: Fix sorting in percent_rmt_hitm_cmp() perf mem: Trace physical address for Arm SPE events perf list: Update event description for IBM zEC12/zBC12 to latest level perf list: Update event description for IBM z196/z114 to latest level perf list: Update event description for IBM z15 to latest level perf list: Update event description for IBM z14 to latest level perf list: Update event description for IBM z13 to latest level perf list: Update event description for IBM z10 to latest level perf list: Add IBM z16 event description for s390 perf record: Support sample-read topdown metric group for hybrid platforms perf lock: Change to synthesize task events perf unwind: Fix segbase for ld.lld linked objects perf test arm-spe: Check if perf-record hangs when recording workload with forks perf docs: Correct typo of event_sources perf evlist: Extend arch_evsel__must_be_in_group to support hybrid systems
