[V7,1/7] spi: Add stacked and parallel memories support in SPI core

Commit Message

Mahapatra, Amit Kumar April 6, 2023, 6:53 a.m. UTC

For supporting multiple CS the SPI device need to be aware of all the CS
values. So, the "chip_select" member in the spi_device structure is now an
array that holds all the CS values.

spi_device structure now has a "cs_index_mask" member. This acts as an
index to the chip_select array. If nth bit of spi->cs_index_mask is set
then the driver would assert spi->chip_select[n].

In parallel mode all the chip selects are asserted/de-asserted
simultaneously and each byte of data is stored in both devices, the even
bits in one, the odd bits in the other. The split is automatically handled
by the GQSPI controller. The GQSPI controller supports a maximum of two
flashes connected in parallel mode. A SPI_CONTROLLER_MULTI_CS flag bit is
added in the spi controntroller flags, through ctlr->flags the spi core
will make sure that the controller is capable of handling multiple chip
selects at once.

For supporting multiple CS via GPIO the cs_gpiod member of the spi_device
structure is now an array that holds the gpio descriptor for each
chipselect.

Multi CS support using GPIO is not tested due to unavailability of
necessary hardware setup.

Multi CS configuration with one native CS and one GPIO CS is not supported
as this configuration could not be tested due to unavailability of
necessary hardware setup.

I've tested this chain on a released laptop (HP EliteBook 840 G9)
which uses
SPI to interface to 2 amps, one amp uses a native CS and the other
uses a
GPIO CS, and I noticed that when using this chain, the second amp no
longer
works.

Thanks,
Stefan Binding

Thank you for sharing the logs.
As per our analysis the spi->cs_gpiod[0] is getting messed up while 
setting it in __spi_add_device( ).
Is it possible for you to do the following changes on top of this patch 
series & re-run your test.

After applying this patch series, in drivers/spi/spi.c file replace the 
following code snippet in __spi_add_device( ) function defination.

if (ctlr->cs_gpiods) {
        for (idx = 0; idx < SPI_CS_CNT_MAX; idx++)
                spi_set_csgpiod(spi, idx, ctlr->cs_gpiods[spi_get_chipselect(spi, idx)]);
}

with the below code snippet

if (ctlr->cs_gpiods) {
        for (idx = 0; idx < SPI_CS_CNT_MAX; idx++) {
                if (!(idx != 0 && !spi_get_chipselect(spi, idx)))
                        spi_set_csgpiod(spi, idx, ctlr->cs_gpiods[spi_get_chipselect(spi, idx)]);
        }
} 

then re-run your test.

Regards,
Amit

> >>>>> then the driver would assert spi->chip_select[n].

> >>>>> SPI_CONTROLLER_MULTI_CS flag bit is added in the spi
> >>>>> controntroller flags, through
> >>>>> ctlr->flags the spi
> >>>> core
> >>>>> will make sure that the controller is capable of handling multiple
> >>>> chip
> >>>>> selects at once.
> >>>>>
> >>>>> For supporting multiple CS via GPIO the cs_gpiod member of the

> >>>>> Multi CS configuration with one native CS and one GPIO CS is not

Thanks for the logs.

Could you please confirm that your test case was passing with 
https://github.com/torvalds/linux/commit/303feb3cc06ac0665d0ee9c1414941200e60e8a3 patch
but it is failing with the current patch series ?  

Regarding the failure 
The logs suggest that we are trying to access an invalid pointer while 
calling the gpiod_set_value_cansleep( ) API.
This could be possible if the cs_num is corrupted and we are trying to 
access an invalid spi->cs_gpiod[ ]. 
To confirm the same could you please do the following changes in the 
code and re-test.

After applying this patch series, in drivers/spi/spi.c file replace the 
following code snippet in __spi_add_device( ) function definition.
if (ctlr->cs_gpiods) {
        for (idx = 0; idx < SPI_CS_CNT_MAX; idx++)
                spi_set_csgpiod(spi, idx, ctlr->cs_gpiods[spi_get_chipselect(spi, idx)]); 
}

with the below code snippet

if (ctlr->cs_gpiods) {
        for (idx = 0; idx < SPI_CS_CNT_MAX; idx++) {
                if (!(idx != 0 && !spi_get_chipselect(spi, idx))) {
		printk("%s( ) [%d] cs[%d] = [%d]\n", __func__, __LINE__, idx, spi_get_chipselect(spi, idx));
		spi_set_csgpiod(spi, idx, ctlr->cs_gpiods[spi_get_chipselect(spi, idx)]);
	}
        }
}

And at the start of  spi_set_cs( ) function in drivers/spi/spi.c file add 
the following print statements.

printk("%s( ) [%d] spi->cs_index_mask == [%d]\n", __func__, __LINE__, spi->cs_index_mask);
printk("%s( ) [%d] cs_num == [%d]\n", __func__, __LINE__, cs_num);

Thanks,
Amit

I retested with the latest master kernel
https://github.com/torvalds/linux/commit/33afd4b76393627477e878b3b195d606e585d816

That particular commit id you posted does not work, due to a different 
issue which was fixed in a later commit.

Thanks a lot for the dmesg log.
Here the __ffs() is creating the issue. __ffs() behavior is undefined if 
no set bits exist in spi->cs_index_mask , as a result random value
(i.e, 64) is assigned to cs_num.
I think this could be fixed by replacing __ffs() with ffs() calls. 
To confirm the same could you please apply the attached patch on top of 
this patch series and re-test. If it works fine, then for sanity kindly 
rerun by removing the printk lines.

Thanks,
Amit

I tested the patch (with and without the prints) on a number of systems 
we have
which use multiple SPI Chip Select GPIOs, and it looks like with this 
patch, they
are all working now.
