2022-02-23ata: pata_hpt37x: disable primary channel on HPT371Sergey Shtylyov1-0/+14
The HPT371 chip physically has only one channel, the secondary one, however the primary channel registers do exist! Thus we have to manually disable the non-existing channel if the BIOS hasn't done this already. Similarly to the pata_hpt3x2n driver, always disable the primary channel.

2022-02-08ata: libata-core: Disable TRIM on M88V29Zoltán Böszörményi1-0/+1
This device is a CF card, or possibly an SSD in CF form factor. It supports NCQ and high speed DMA. While it also advertises TRIM support, I/O errors are reported when the discard mount option fstrim is used. TRIM also fails when disabling NCQ and not just as an NCQ command. TRIM must be disabled for this device. Signed-off-by: Zoltán Böszörményi <zboszor@gmail.com> Signed-off-by: Damien Le Moal <damien.lemoal@opensource.wdc.com>
2022-02-08ata: sata_fsl: fix sscanf() and sysfs_emit() format stringsDamien Le Moal1-9/+7
Use the %u format for unsigned int parameters handling with sscanf() and sysfs_emit() to avoid compilation warnings. In fsl_sata_rx_watermark_store(), the call to sscanf() to parse a single argument is replaced with a call to kstrtouint(). While at it, also replace the printk(KERN_ERR) calls with dev_err() calls and fix blank lines in fsl_sata_rx_watermark_store().

2022-02-07ata: libata-core: Fix ata_dev_config_cpr()Damien Le Moal1-8/+6
The concurrent positioning ranges log page 47h is a general purpose log page and not a subpage of the indentify device log. Using ata_identify_page_supported() to test for concurrent positioning ranges support is thus wrong. ata_log_supported() must be used. Furthermore, unlike other advanced ATA features (e.g. NCQ priority), accesses to the concurrent positioning ranges log page are not gated by a feature bit from the device IDENTIFY data. Since many older drives react badly to the READ LOG EXT and/or READ LOG DMA EXT commands isued to read device log pages, avoid problems with older drives by limiting the concurrent positioning ranges support detection to drives implementing at least the ACS-4 ATA standard (major version 11). This additional condition effectively turns ata_dev_config_cpr() into a nop for older drives, avoiding problems in the field.

2022-02-04ata: libata-core: Introduce ATA_HORKAGE_NO_LOG_DIR horkageAnton Lundin1-0/+10
06f6c4c6c3e8 ("ata: libata: add missing ata_identify_page_supported() calls") introduced additional calls to ata_identify_page_supported(), thus also adding indirectly accesses to the device log directory log page through ata_log_supported(). Reading this log page causes SATADOM-ML 3ME devices to lock up. Introduce the horkage flag ATA_HORKAGE_NO_LOG_DIR to prevent accesses to the log directory in ata_log_supported() and add a blacklist entry with this flag for "SATADOM-ML 3ME" devices.

2022-01-27ata: pata_platform: Fix a NULL pointer dereference in __pata_platform_probe()Zhou Qingyang1-0/+2
In __pata_platform_probe(), devm_kzalloc() is assigned to ap->ops and there is a dereference of it right after that, which could introduce a NULL pointer dereference bug. Fix this by adding a NULL check of ap->ops. This bug was found by a static analyzer. Builds with 'make allyesconfig' show no new warnings, and our static analyzer no longer warns about this code.

Add support for the AMD A85 FCH (Hudson D4) AHCI adapter. Since this adapter does not require the default 200 ms debounce delay in sata_link_resume(), create a new board board_ahci_no_debounce_delay with the link flag ATA_LFLAG_NO_DEBOUNCE_DELAY, and, for now, configure the AMD A85 FCH (Hudson D4) to use it.

2022-01-14ata: pata_of_platform: Use platform_get_irq_optional() to get the interruptLad Prabhakar1-3/+12
platform_get_resource(pdev, IORESOURCE_IRQ, ..) relies on static allocation of IRQ resources in DT core code, this causes an issue when using hierarchical interrupt domains using "interrupts" property in the node as this bypasses the hierarchical setup and messes up the irq chaining. In preparation for removal of static setup of IRQ resource from DT core code use platform_get_irq_optional(). Note the code does not set the IRQ flags as this is handled automatically for DT.

2022-01-14ata: fix read_id() ata port operation interfaceDamien Le Moal6-22/+21
Drivers that need to tweak a device IDENTIFY data implement the read_id() port operation. The IDENTIFY data buffer is passed as an argument to the read_id() operation for drivers to use. However, when this operation is called, the IDENTIFY data is not yet converted to CPU endian and contains le16 words. Change the interface of the read_id operation to pass a __le16 * pointer to the IDENTIFY data buffer to clarify the buffer endianness. Fix the pata_netcell, pata_it821x, ahci_xgene, ahci_ceva and ahci_brcm drivers implementation of this operation and modify the code to corretly deal with identify data words manipulation to avoid sparse warnings such as: drivers/ata/ahci_xgene.c:262:33: warning: invalid assignment: &= drivers/ata/ahci_xgene.c:262:33: left side has type unsigned short drivers/ata/ahci_xgene.c:262:33: right side has type restricted __le16 Signed-off-by: Damien Le Moal <damien.lemoal@opensource.wdc.com> Reviewed-by: Hannes Reinecke <hare@suse.de>
