2024-01-31pinctrl: renesas: pinctrl-rzg2l: Add the missing port pins P19 to P28Lad Prabhakar2-9/+208
Add the missing port pins P19 to P28 for RZ/Five SoC. These additional pins provide expanded capabilities and are exclusive to the RZ/Five SoC. Couple of port pins have different configuration and are not identical for the complete port so introduce struct rzg2l_variable_pin_cfg to handle such cases and introduce the PIN_CFG_VARIABLE macro. The actual pin config is then assigned in rzg2l_pinctrl_get_variable_pin_cfg(). Add an additional check in rzg2l_gpio_get_gpioint() to only allow GPIO pins which support interrupt facility. While at define RZG2L_GPIO_PORT_PACK() using RZG2L_GPIO_PORT_SPARSE_PACK(). Update the gpio-ranges property in the RZ/Five SoC DTSI, as it must match the driver.

2024-01-31pinctrl: renesas: rzg2l: Include pinmap in RZG2L_GPIO_PORT_PACK() macroLad Prabhakar1-27/+29
Currently we assume all the port pins are sequential ie always PX_0 to PX_n (n=1..7) exist, but on RZ/Five SoC we have additional pins P19_1 to P28_5 which have holes in them, for example only one pin on port19 is available and that is P19_1 and not P19_0. So to handle such cases include pinmap for each port which would indicate the pin availability on each port. As the pincount can be calculated based on pinmap drop this from RZG2L_GPIO_PORT_PACK() macro. Previously we had a max of 7 pins on each port but on RZ/Five Port-20 has 8 pins, so move the single pin configuration to BIT(63).

2024-01-31pinctrl: renesas: checker: Limit cfg reg enum checks to provided IDsGeert Uytterhoeven1-1/+3
If the number of provided enum IDs in a variable width config register description does not match the expected number, the checker uses the expected number for validating the individual enum IDs. However, this may cause out-of-bounds accesses on the array holding the enum IDs, leading to bogus enum_id conflict warnings. Worse, if the bug is an incorrect bit field description (e.g. accidentally using "12" instead of "-12" for a reserved field), thousands of warnings may be printed, overflowing the kernel log buffer. Fix this by limiting the enum ID check to the number of provided enum IDs.

2024-01-31pinctrl: renesas: rzg2l: Fix locking in rzg2l_dt_subnode_to_map()Claudiu Beznea1-10/+10
Commit d3aaa7203a17 ("pinctrl: renesas: rzg2l: Add pin configuration support for pinmux groups") introduced the possibility to parse pin configuration for pinmux groups. It did that by calling rzg2l_map_add_config() at the end of rzg2l_dt_subnode_to_map() and jumping to the remove_group label in case rzg2l_map_add_config() failed. But if that happens, the mutex will already be unlocked, thus this it will lead to double mutex unlock operation. To fix this move the rzg2l_map_add_config() call just after all the name argument is ready and before the mutex is locked. There is no harm in doing this, as this only parses the data from device tree that will be further processed by pinctrl core code.

2024-01-21bcachefs: Prep work for variable size btree node buffersKent Overstreet18-97/+87
bcachefs btree nodes are big - typically 256k - and btree roots are pinned in memory. As we're now up to 18 btrees, we now have significant memory overhead in mostly empty btree roots. And in the future we're going to start enforcing that certain btree node boundaries exist, to solve lock contention issues - analagous to XFS's AGIs. Thus, we need to start allocating smaller btree node buffers when we can. This patch changes code that refers to the filesystem constant c->opts.btree_node_size to refer to the btree node buffer size - btree_buf_bytes() - where appropriate.

The variable tmp is being assigned a value but it isn't being read afterwards. The assignment is redundant and so tmp can be removed.

drop_locks_do() should not be used in a fastpath without first trying the do in nonblocking mode - the unlock and relock will cause excessive transaction restarts and potentially livelocking with other threads that are contending for the same locks.

Factor out bch2_journal_bufs_to_text(), and use it in the journal_entry_full() tracepoint; when we can't get a journal reservation we need to know the outstanding journal entry sizes to know if the problem is due to excessive flushing. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2024-01-21bcachefs: Avoid flushing the journal in the discard pathKent Overstreet1-19/+41
When issuing discards, we may need to flush the journal if there's too many buckets that can't be discarded until a journal flush. But the heuristic was bad; we should be comparing the number of buckets that need to flushes against the number of free buckets, not the number of buckets we saw.

2024-01-21bcachefs: bch2_kthread_io_clock_wait() no longer sleeps until full amountKent Overstreet1-2/+2
Drop t he loop in bch2_kthread_io_clock_wait(): this allows the code that uses it to be woken up for other reasons, and fixes a bug where rebalance wouldn't wake up when a scan was requested. This raises the possibility of spurious wakeups, but callers should always be able to handle that reasonably well. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
