We need to be able to get from an irq number to a struct msi_desc. The msi_desc array in msi.c had several short comings the big one was that it could not be used outside of msi.c. Using irq_data in struct irq_desc almost worked except on some architectures irq_data needs to be used for something else. So this patch adds a msi_desc pointer to irq_desc, adds the appropriate wrappers and changes all of the msi code to use them. The dynamic_irq_init/cleanup code was tweaked to ensure the new field is left in a well defined state. Signed-off-by: NEric W.

The function msi_lookup_irq was horrible. As a side effect of running it changed dev->irq, and then the callers would need to change it back. In addition it does a global scan through all of the irqs, which seems to be the sole justification of the msi_lock. To remove the neede for msi_lookup_irq I added first_msi_irq to struct pci_dev. Then depending on the context I replaced msi_lookup_irq with dev->first_msi_irq, dev->msi_enabled, or dev->msix_enabled. msi_enabled and msix_enabled were already present in pci_dev for other reasons.

This patch adds the following changes into generic PCI code especially for PCI legacy I/O port free drivers. - Added new pci_request_selected_regions() and pci_release_selected_regions() for PCI legacy I/O port free drivers in order to request/release only the selected regions. - Added helper routine pci_select_bars() which makes proper mask of BARs from the specified resource type. This would be very helpful for users of pci_enable_device_bars().

Some HID devices by Apple have both keyboard and mouse interfaces; the keyboard interface is handled by usbhid, but the mouse (really touchpad) interface must be handled by the separate 'appletouch' driver. Using HID_QUIRK_IGNORE will make hiddev ignore both interfaces, therefore a new quirk flag to ignore only the mouse interface is required.

Add new quirk HID_QUIRK_SKIP_OUTPUT_REPORTS to skip output reports when enumerating reports on a hid-input device. Add this quirk and HID_QUIRK_MULTI_INPUT to 0810:0001. PantherLord Twin USB Joystick, 0810:0001 has separate input reports for 2 distinct game controllers in the same interface, so it needs HID_QUIRK_MULTI_INPUT. However, the device also contains one output report per controller which is used to control the force feedback function, and we do not want those to appear as separate input devices as well. The simplest approach seems to be to add a quirk to skip output reports on 0810:0001, and allow the force feedback driver to handle those.

Many controllers have an upper limit on the number of blocks that can be transferred in one request. Allow the host drivers to specify this and make sure we avoid hitting this limit. Also change the max_sectors field to avoid confusion. This makes it map less directly to the block layer limits, but as they didn't apply directly on MMC cards anyway, this isn't a great loss.

Hardware does not say whether card was inserted or removed when reporting socket events. Moreover, during suspend, media can be removed or switched to some other card type without notification. Therefore, for each socket in the change set the following is performed: 1. If there's active device in the socket it's unregistered 2. Media detection is performed 3. If detection recognizes supportable media, new device is registered This patch also alters some macros and variable names to enhance clarity.

In order to support correct suspend and resume several changes were needed: 1. Switch from work_struct to tasklet for command handling. When device suspend is called workqueues are already frozen and can not be used. 2. Separate host initialization code from driver's probe and don't rely on interrupts for host initialization. This, in turn, addresses two problems: a) Resume needs to re-initialize the host, but can not assume that device interrupts were already re-armed. b) Previously, probe will return successfully before really knowing the state of the host, as host interrupts were not armed in time. Now it uses polling to determine the real host state before returning. 3. Separate termination code from driver's remove. Termination may be caused by resume, if media changed type or became unavailable during suspend. Signed-off-by: NAlex Dubov <oakad@yahoo.com> Signed-off-by: NPierre Ossman <drzeus@drzeus.cx>

由 Philip Langdale 提交于
Thanks to the generous donation of an SDHC card by John Gilmore, and the surprisingly enlightened decision by the SD Card Association to publish useful specs, I've been able to bash out support for SDHC. The changes are not too profound: i) Add a card flag indicating the card uses block level addressing and check it in the block driver. As we never took advantage of byte-level addressing, this simply involves skipping the block -> byte translation when sending commands. ii) The layout of the CSD is changed - a set of fields are discarded to make space for a larger C_SIZE. We did not reference any of the discarded fields except those related to the C_SIZE. iii) Read and write timeouts are fixed values and not calculated from CSD values. iv) Before invoking SEND_APP_OP_COND, we must invoke the new SEND_IF_COND to inform the card we support SDHC.

由 Darren Salt 提交于
Support for these devices was broken for 2.6.18-rc1 and later by commit 146ad66e, which added voltage level support. This restores the previous behaviour for these devices by ensuring that when the voltage is changed, only one write to set the voltage is performed. It may be that both writes are needed if the voltage is being changed between two non-zero values or that it's safe to ensure that only one write is done if the hardware only supports one voltage; I don't know whether either is the case nor can I test since I have only the one SD reader (1524:0550), and it supports just the one voltage.

This is based on a patch by Eric W. Biederman, who pointed out that pid namespaces are still fake, and we only have one ever active. So for the time being, we can modify any code which could access tsk->nsproxy->pid_ns during task exit to just use &init_pid_ns instead, and move the exit_task_namespaces call in do_exit() back above exit_notify(), so that an exiting nfs server has a valid tsk->sighand to work with. Long term, pulling pid_ns out of nsproxy might be the cleanest solution. Signed-off-by: NEric W.

Fix exit race by splitting the nsproxy putting into two pieces. First piece reduces the nsproxy refcount. If we dropped the last reference, then it puts the mnt_ns, and returns the nsproxy as a hint to the caller. Else it returns NULL. The second piece of exiting task namespaces sets tsk->nsproxy to NULL, and drops the references to other namespaces and frees the nsproxy only if an nsproxy was passed in. A little awkward and should probably be reworked, but hopefully it fixes the NFS oops. Signed-off-by: NSerge E.

The apple powerbook people are used to switch the pb_fnmode setting at runtime through writing to sysfs, altering the module parameter value. This was broken for them in 2.6.20-rc1 when generic HID layer was introduced, as the pb_fnmode flag was made per-hiddevice, instead of global variable. This patch moves the pb_fnmode module parameter from usbhid module to hid module, but apart from that retains backward compatibility with respect to changing the mode through sysfs.

If a GFP_KERNEL allocation is attempted in md while the mddev_lock is held, it is possible for a deadlock to eventuate. This happens if the array was marked 'clean', and the memalloc triggers a write-out to the md device. For the writeout to succeed, the array must be marked 'dirty', and that requires getting the mddev_lock. So, before attempting a GFP_KERNEL allocation while holding the lock, make sure the array is marked 'dirty' (unless it is currently read-only).

nfsd defines a type 'encode_dent_fn' which is much like 'filldir_t' except that the first pointer is 'struct readdir_cd *' rather than 'void *'. It then casts encode_dent_fn points to 'filldir_t' as needed. This hides any other type mismatches between the two such as the fact that the 'ino' arg recently changed from ino_t to u64. So: get rid of 'encode_dent_fn', get rid of the cast of the function type, change the first arg of various functions from 'struct readdir_cd *' to 'void *', and live with the fact that we have a little less type checking on the calling of these functions now. Less internal (to nfsd) checking offset by more external checking, which is more important. Thanks to Gabriel Paubert <paubert@iram.es> for discovering this and providing an initial patch.
