2022-10-13soc: sifive: ccache: Rename SiFive L2 cache to Composable cache.Greentime Hu2-7/+7
Since composable cache may be L3 cache if there is a L2 cache, we should use its original name composable cache to prevent confusion. There are some new lines were generated due to adding the compatible "sifive,ccache0" into ID table and indent requirement. The sifive L2 has been renamed to sifive CCACHE, EDAC driver needs to apply the change as well.

Current i10nm_edac only supports firmware decoder (ACPI DSM methods). MCA bank registers of Ice Lake or Tremont CPUs contain the information to decode DDR memory errors.

The performance of driver decoder[1] is better than the performance of firmware decoder[2], especially on frequent correctable errors. So use the driver decoder first, fall back to firmware decoder if the driver decoder is unavailable. Also rename the function pointer skx_decode to driver_decode (better name to contrast with adxl_decode).

git://git.kernel.org/pub/scm/linux/kernel/git/ras/ras Pull EDAC updates from Borislav Petkov: - Switch ghes_edac to use the CPER error reporting routines and simplify the code considerably this way - Rip out the silly edac_align_ptr() contraption which was computing the size of the private structures of each driver and thus allowing for a one-shot memory allocation. This was clearly unnecessary and confusing so switch to simple and boring kmalloc* calls. - Last but not least, the usual garden variety of fixes, cleanups and improvements all over EDAC land * tag 'edac_updates_for_v5.19_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/ras/ras: EDAC/xgene: Fix typo processsors -> processors EDAC/i5100: Remove unused inline function i5100_nrecmema_dm_buf_id() EDAC: Use kcalloc() EDAC/ghes: Change ghes_hw from global to static EDAC/armada_xp: Use devm_platform_ioremap_resource() EDAC/synopsys: Add a SPDX identifier EDAC/synopsys: Add driver support for i.MX platforms EDAC/dmc520: Don't print an error for each unconfigured interrupt line EDAC/mc: Get rid of edac_align_ptr() EDAC/device: Sanitize edac_device_alloc_ctl_info() definition EDAC/device: Get rid of the silly one-shot memory allocation in edac_device_alloc_ctl_info() EDAC/pci: Get rid of the silly one-shot memory allocation in edac_pci_alloc_ctl_info() EDAC/mc: Get rid of silly one-shot struct allocation in edac_mc_alloc() efi/cper: Reformat CPER memory error location to more readable EDAC/ghes: Unify CPER memory error location reporting efi/cper: Add a cper_mem_err_status_str() to decode error description powerpc/85xx: Remove fsl,85... bindings

2022-04-19EDAC/dmc520: Don't print an error for each unconfigured interrupt lineTyler Hicks1-1/+1
The dmc520 driver requires that at least one interrupt line, out of the ten possible, is configured. The driver prints an error and returns -EINVAL from its .probe function if there are no interrupt lines configured. Don't print a KERN_ERR level message for each interrupt line that's unconfigured as that can confuse users into thinking that there is an error condition. Before this change, the following KERN_ERR level messages would be reported if only dram_ecc_errc and dram_ecc_errd were configured in the device tree: dmc520 68000000.dmc: IRQ ram_ecc_errc not found dmc520 68000000.dmc: IRQ ram_ecc_errd not found dmc520 68000000.dmc: IRQ failed_access not found dmc520 68000000.dmc: IRQ failed_prog not found dmc520 68000000.dmc: IRQ link_err not dmc520 68000000.dmc: IRQ temperature_event not found dmc520 68000000.dmc: IRQ arch_fsm not found dmc520 68000000.dmc: IRQ phy_request not found Fixes: 1088750d7839 ("EDAC: Add EDAC driver for DMC520") Reported-by: Sinan Kaya <okaya@kernel.org> Signed-off-by: Tyler Hicks <tyhicks@linux.microsoft.com> Signed-off-by: Borislav Petkov <bp@suse.de> Link: https://lore.kernel.org/r/20220111163800.22362-1-tyhicks@linux.microsoft.com

2022-04-11EDAC/device: Get rid of the silly one-shot memory allocation in ↵Borislav Petkov3-71/+57
edac_device_alloc_ctl_info() Use boring kzalloc() instead. Add pointers to the different allocated members in struct edac_device_ctl_info for easier freeing later. One of the reasons, perhaps, why it was done this way is to be able to do a single kfree(ctl_info) without having to kfree() the other parts of the struct too but that is not nearly a sensible reason as to why there should be this obscure pointer alignment. There should be no functional changes resulting from this. Signed-off-by: Borislav Petkov <bp@suse.de> Link: https://lore.kernel.org/r/20220310095254.1510-4-bp@alien8.de

2022-04-05x86/amd_nb: Unexport amd_cache_northbridges()Muralidhara M K1-1/+1
amd_cache_northbridges() is exported by amd_nb.c and is called by amd64-agp.c and amd64_edac.c modules at module_init() time so that NB descriptors are properly cached before those drivers can use them. However, the init_amd_nbs() initcall already does call amd_cache_northbridges() unconditionally and thus makes sure the NB descriptors are enumerated. That initcall is a fs_initcall type which is on the 5th group (starting from 0) of initcalls that gets run in increasing numerical order by the init code. The module_init() call is turned into an __initcall() in the MODULE=n case and those are device-level initcalls, i.e., group 6. Therefore, the northbridges caching is already finished by the time module initialization starts and thus the correct initialization order is retained. Unexport amd_cache_northbridges(), update dependent modules to call amd_nb_num() instead. While at it, simplify the checks in amd_cache_northbridges().

2022-03-16EDAC/altera: Add SDRAM ECC check for U-BootRabara Niravkumar L1-1/+39
A bug in legacy U-Boot causes a crash during SDRAM boot if ECC is not enabled in the bitstream but enabled in the Linux config. Memory mapped read of the ECC Enabled bit was only enabled if U-Boot determined ECC was enabled in the bitstream. The Linux driver checks the ECC enable bit using a memory map read. In the ECC disabled bitstream case, U-Boot didn't enable ECC register memory map reads and since they are not allowed this results in a crash. Always read the ECC Enable register through a SMC call which is always allowed and it works with legacy and current U-Boot.

2022-02-24EDAC/amd64: Add new register offset support and related changesYazen Ghannam2-16/+78
Introduce a "family flags" bitmask that can be used to indicate any special behavior needed on a per-family basis. Add a flag to indicate a system uses the new register offsets introduced with Family 19h Model 10h. Use this flag to account for register offset changes, a new bitfield indicating DDR5 use on a memory controller, and to set the proper number of chip select masks. Rework f17_addr_mask_to_cs_size() to properly handle the change in chip select masks. And update code comments to reflect the updated Chip Select, DIMM, and Mask relationships.
