2020-09-25drivers/net/ethernet: clean up mis-targeted commentsJesse Brandeburg
As part of the W=1 cleanups for ethernet, a million [*] driver comments had to be cleaned up to get the W=1 compilation to succeed. This change finally makes the drivers/net/ethernet tree compile with W=1 set on the command line. NOTE: The kernel uses kdoc style (see Documentation/process/kernel-doc.rst) when documenting code, not doxygen or other styles. After this patch the x86_64 build has no warnings from W=1, however scripts/kernel-doc says there are 1545 more warnings in source files, that I need to develop a script to fix in a followup patch. The errors fixed here are all kdoc of a few classes, with a few outliers: In file included from drivers/net/ethernet/qlogic/netxen/netxen_nic_hw.c:10: drivers/net/ethernet/qlogic/netxen/netxen_nic.h:1193:18: warning: ‘FW_DUMP_LEVELS’ defined but not used [-Wunused-const-variable=] 1193 | static const u32 FW_DUMP_LEVELS[] = { 0x3, 0x7, 0xf, 0x1f, 0x3f, 0x7f, 0xff }; | ^~~~~~~~~~~~~~ ... repeats 4 times... drivers/net/ethernet/sun/cassini.c:2084:24: warning: suggest braces around empty body in an ‘else’ statement [-Wempty-body] 2084 | RX_USED_ADD(page, i); drivers/net/ethernet/natsemi/ns83820.c: In function ‘phy_intr’: drivers/net/ethernet/natsemi/ns83820.c:603:6: warning: variable ‘tbisr’ set but not used [-Wunused-but-set-variable] 603 | u32 tbisr, tanar, tanlpar; | ^~~~~ drivers/net/ethernet/natsemi/ns83820.c: In function ‘ns83820_get_link_ksettings’: drivers/net/ethernet/natsemi/ns83820.c:1207:11: warning: variable ‘tanar’ set but not used [-Wunused-but-set-variable] 1207 | u32 cfg, tanar, tbicr; | ^~~~~ drivers/net/ethernet/packetengines/yellowfin.c:1063:18: warning: variable ‘yf_size’ set but not used [-Wunused-but-set-variable] 1063 | int data_size, yf_size; | ^~~~~~~ Normal kdoc fixes: warning: Function parameter or member 'x' not described in 'y' warning: Excess function parameter 'x' description in 'y' warning: Cannot understand <string> on line <NNN> - I thought it was a doc line [*] - ok it wasn't quite a million, but it felt like it.

With legacy PM, drivers themselves were responsible for managing the device's power states and takes care of register states. After upgrading to the generic structure, PCI core will take care of required tasks and drivers should do only device-specific operations.

Hence, this patch pulls out the relevant information from the ks8851_mll.c on how to access the bus, but uses the common ks8851.c code.

If this has noticeable performance impact on the SPI variant of KS8851, then we should consider using regmap to abstract the SPI and parallel bus options and in case of SPI, permit regmap to merge register reads of neighboring registers into single, longer, read.

This patch reverts 58292104832f ("net: ks8851-ml: Fix 16-bit IO operation") and edacb098ea9c ("net: ks8851-ml: Fix 16-bit data access"), because it turns out these were only necessary due to buggy hardware. This patch adds a check for such a buggy hardware to prevent any such mistakes again. While working further on the KS8851 driver, it came to light that the KS8851-16MLL is capable of switching bus endianness by a hardware strap, EESK pin. If this strap is incorrect, the IO accesses require such endian swapping as is being reverted by this patch. Such swapping also impacts the performance significantly. Hence, in addition to removing it, detect that the hardware is broken, report to user, and fail to bind with such hardware.

2020-02-23net: ks8851-ml: Fix IRQ handling and lockingMarek Vasut
The KS8851 requires that packet RX and TX are mutually exclusive. Currently, the driver hopes to achieve this by disabling interrupt from the card by writing the card registers and by disabling the interrupt on the interrupt controller. This however is racy on SMP. Replace this approach by expanding the spinlock used around the ks_start_xmit() TX path to ks_irq() RX path to assure true mutual exclusion and remove the interrupt enabling/disabling, which is now not needed anymore. Furthermore, disable interrupts also in ks_net_stop(), which was missing before. Note that a massive improvement here would be to re-use the KS8851 driver approach, which is to move the TX path into a worker thread, interrupt handling to threaded interrupt, and synchronize everything with mutexes, but that would be a much bigger rework, for a separate patch.

The Micrel KSZ8851-16MLLI datasheet DS00002357B page 12 states that BE[3:0] signals are active high. This contradicts the measurements of the behavior of the actual chip, where these signals behave as active low. For example, to read the CIDER register, the bus must expose 0xc0c0 during the address phase, which means BE[3:0]=4'b1100. Signed-off-by: Marek Vasut <marex@denx.de> Cc: David S.

2020-02-16net: ks8851-ml: Remove 8-bit bus accessorsMarek Vasut
This driver is mixing 8-bit and 16-bit bus accessors for reasons unknown, however the speculation is that this was some sort of attempt to support the 8-bit bus mode. As per the KS8851-16MLL documentation, all two registers accessed via the 8-bit accessors are internally 16-bit registers, so reading them using 16-bit accessors is fine. The KS_CCR read can be converted to 16-bit read outright, as it is already a concatenation of two 8-bit reads of that register. The KS_RXQCR accesses are 8-bit only, however writing the top 8 bits of the register is OK as well, since the driver caches the entire 16-bit register value anyway. Finally, the driver is not used by any hardware in the kernel right now. The only hardware available to me is one with 16-bit bus, so I have no way to test the 8-bit bus mode, however it is unlikely this ever really worked anyway. If the 8-bit bus mode is ever required, it can be easily added by adjusting the 16-bit accessors to do 2 consecutive accesses, which is how this should have been done from the beginning.
