This patch introduce changes to netcp modules and makefile to build
the driver as dynamic modules. This also convert existing cpsw_ale.c
as a module so that it can be re-used across netcp and ti_cpsw drivers.
This also fixes the issue seen when build using arm allmodconfig
I have made an allmodconfig with this patch and the build succeeds.
make allmodconfig
make uImage LOADADDR=0x80008000; make modules
After the build all of the following .ko files are seen
Note: need to verify this on a platform with TI CPSW.
drivers/net/ethernet/ti/cpsw_ale.ko
drivers/net/ethernet/ti/davinci_cpdma.ko
drivers/net/ethernet/ti/davinci_emac.ko

drivers/net/ethernet/ti/keystone_netcp.ko
drivers/net/ethernet/ti/ti_cpsw.ko
drivers/net/ethernet/ti/tlan.ko
This also has dependency on the following patches for netcp :-

To allow both ti cpsw and keystone netcp to re-use the driver, convert the cpsw ale to a module and configure it through Kconfig option CONFIG_TI_CPSW_ALE. Currently it is statically linked to both TI CPSW and NetCP and this causes issues when the above drivers are built as dynamic modules. This patch addresses this issue While at it, fix the Makefile and code to build both netcp_core and netcp_ethss as dynamic modules. This is needed to support arm allmodconfig. This also requires exporting of API calls provided by netcp_core so that both the above can be dynamic modules.

Probably the best way in the long run is to add a single exported function to cpsw-common.c I just added for the MAC address function. Then all the cpsw like drivers can register with that instead of having tons of custom exported functions. But before doing that, we should have a clear idea what all can be shared. Murali, maybe you can take a look at that? Regards, Tony ^ permalink raw reply [flat|nested] 13+ messages in thread

If understand correctly, what you have done is moved the common mac function and exported the function in cpsw-common.c and called it from cpsw.c. How is this any different from exporting all common functions from cpsw_ale.c as is done today? Not sure what you meant by a single exported function. Are you talking about defining a ale_ops struct of function ptrs and exporting that instead of individual functions? So cpsw_ale_common.c Move all of the common functions here and define them as static. Defined cpsw_ale_ops and export it. cpsw.c and netcp_ethss.c calls something like cpsw_ale_ops.foo(); Murali > > Then all the cpsw like drivers can register with that instead of > having tons of custom exported functions. > > But before doing that, we should have a clear idea what all can > be shared.

I was thinking struct cpsw_common with shared function pointers. Then in cpsw-common.c, export cpsw_register() and cpsw_free() that the cpsw like drivers can use to configure whatever combination of cpsw shared functions it can use. It could be naturally more than one struct, or maybe struct cpsw_ale, struct cpdma and struct netcp could be within the struct cpsw_common. I only attempted to set up a place for future cpsw code sharing with cpsw-common.c. I have not identified what all could be shared, looks like you have a much better idea about that :) By registering cpsw like drivers with cpsw-common allows exporting only a few selected functions instead of exporting tons of custom functions (currently 43 of them).
