Todo List

Class irq_desc

what about IRQ sharing?

Member udelay (unsigned long usecs)

consider l4_busy_wait_us() for short delays

Member __more_kcore (l4_size_t size, l4_uint32_t flags)

consider flags

File mmio.c

WHAT ABOUT THIS?

Member remap_page_range (unsigned long virt_addr, unsigned long phys_addr, unsigned long size, pgprot_t prot)

Hmm, what was the idea of that?!

Member pci_release_region (struct pci_dev *pdev, int bar)

implementation

Member create_proc_entry (const char *name, mode_t mode, struct proc_dir_entry *parent)

implementation

Member remove_proc_entry (const char *name, struct proc_dir_entry *parent)

implementation

Member __cpu_raise_softirq (unsigned cpu, int nr)

only the implementation of tasklets is done in Linux DDE

Member tasklet_vec [NR_CPUS]

Rethink tasklet_vec[1] for more than 1 softirq thread; so NR_CPUS will become NR_SOFTIRQ_THREADS later

Member softirq_tid [SOFTIRQ_THREADS]

Redesign for more than one thread.

Member dde_softirq_thread (int num)

priorities

Member dde_timer_thread (void)

priorities

Group mod_mm_addr

error handling

what about I/O pages?

implement remove_region()

introduce region names

Member probe_irq_on (unsigned long val)

implementation

Member probe_irq_off (unsigned long val)

implementation

Member free_irq (unsigned int irq, void *dev_id)

Stop IRQ-Thread

Release IRQ

Member request_irq (unsigned int irq, void(*handler)(int, void *, struct pt_regs *), unsigned long flags, const char *dev_name, void *dev_id)

reattachment

Member FASTCALL (free_pages(unsigned long addr, unsigned int order))

implementation

Member FASTCALL (__get_free_pages(unsigned int gfp_mask, unsigned int order))

Physical alignment is not yet ensured.

Member pci_set_master (struct pci_dev *dev)

Who panics if it fails?

Member pci_alloc_consistent (struct pci_dev *hwdev, size_t size, dma_addr_t *dma_handle)

Is this really a PCI issue?!

Member pci_free_consistent (struct pci_dev *hwdev, size_t size, void *vaddr, dma_addr_t dma_handle)

Is this really a PCI issue?!

Member l4dde_pci_init ()

consider pcibus no as parameter

Group mod_res

I/O memory as dataspaces?!

region handling

Member release_resource (struct resource *res)

implementation

Member tqueue_lock

Implement this if any useful driver needs it.

encapsulate tqueue_lock like tasklet_vec providing proper interface

Member l4dde_softirq_init ()

configuration with more (than 1) threads
