Subject: Re: [patch 4/5] Staging: vme: add Tundra TSI148 VME-PCI Bridge
driver
Greg, Martyn,
please have a look at our tsi148 driver, available at:
http://repo.or.cz/w/tsi148vmebridge.git
Whenever you encounter a reference to 'CES', ignore it,
it's a CERN thing for easing our lives porting drivers from
LynxOS.
I could post the driver to LKML for review if you want; I would
remove that CES crap before posting. I put this off because
I knew it would never get merged before there was some generic
vme glue supporting it. However now we're getting there so
it's probably a good time to get cracking with this task.
Martyn, a few comments about your driver, haven't had much
time to dig very deep.
- again, use mutexes instead of semaphores
- The DMA code looks rather messy; I mean stuff like this:
> +#if 0
> + /* XXX Still todo */
> + for (x = 0; x < 8; x++) { /* vme block size */
> + if ((32 << x) >= vmeDma->maxVmeBlockSize) {
> + break;
> + }
> + }
> + if (x == 8)
> + x = 7;
> + dctlreg |= (x << 12);
> +
> + for (x = 0; x < 8; x++) { /* pci block size */
> + if ((32 << x) >= vmeDma->maxPciBlockSize) {
> + break;
> + }
> + }
> + if (x == 8)
> + x = 7;
> + dctlreg |= (x << 4);
> +
> + if (vmeDma->vmeBackOffTimer) {
and the ifdefs 0..
- correct me if I'm wrong, but does the slave need to know the
window number he wants for his device? See:
> +int tsi148_slave_get(struct vme_slave_resource *image, int *enabled,
> + unsigned long long *vme_base, unsigned long long *size,
> + dma_addr_t *pci_base, vme_address_t *aspace, vme_cycle_t *cycle)
> +{

> + unsigned int vme_bound_low, vme_bound_high;
> + unsigned int pci_offset_low, pci_offset_high;
> + unsigned long long vme_bound, pci_offset;
> +
> +
> + i = image->number;
If that's the case, this is totally broken; in fact, even if you
kept a list somewhere up on the generic vme layer keeping track
of the already used windows (images?) to avoid any clashes,
in practice you'd very soon run out of windows: 8 modules, 8
mappings, 8 windows. And you're dead.
In a crate we have up to 20 modules, each of them with at least
one address space to be mapped. To make this work we do the
following:
* The tsi148 has 1GB of address space available for mapping,
which is further divided into 8 windows, with a unique address
modifier per window.
* Say you have 15 modules that need to map 1MB each, all of them
with the same address modifier (AM).
Then what the slave driver requests is *not* a window, is what we
call a 'vme mapping', which means "do whatever you want but give
me a kernel address that points at this VME address, mapping with
this size and AM".
Our tsi148 driver notices then that there's already a window for
that AM, so it just appends the mapping to the existing window.
So at the end of the day only one window is used for all those
mappings, which are nicely piled together.
Please clarify me how this is handled in your driver. The
bottom line is to ensure that
a) Many different modules can peacefully co-exist on a crate
b) Drivers should know nothing about what else is on your crate
E.
